Stainless Steel Welding Machine Requirements

It can be quite a task choosing the right welding machine, especially when you’re dealing with stainless steel. Let’s dive in, as I share my experience and tips on how to navigate this.

To set things straight, welding stainless steel requires a machine that’s a bit different from those used for other metals. I remember my first attempt at welding stainless steel – I was a small shop welder who thought all machines were created equal. Boy, was I wrong! The experience was frustrating and I learned the hard way. From then on, I knew that selecting the right machine was vital to achieving excellent stainless steel welding results.

Here are some aspects you need to consider:

Brand

Now, this is crucial. In my experience, opting for a well-known brand is always a safer bet. I’m not saying smaller, lesser-known brands won’t do the job, but popular brands usually provide more reliable machines and better customer service.

When I started, I used a relatively unknown brand’s welding machine. Unfortunately, their customer support was lackluster when I ran into some minor issues. I switched to a more renowned brand, and voila, the quality of service and performance was considerably better. This isn’t a hard-and-fast rule, but I’ve observed it over time.

Welding Process

Understanding the welding process is integral when choosing your welding machine. MIG (Metal Inert Gas) welding machines and TIG (Tungsten Inert Gas) welding machines are the most commonly used stainless steel welding machines.

From my experience, if you’re dealing with thicker stainless steel or doing high volume welding, a MIG welding machine might be your best bet. You might want to go for a TIG welding machine for more detailed, finer work.

I remember my first project involved a lot of detailed work on stainless steel pipe. My trusty MIG machine didn’t offer the precision I needed. So, I switched to a TIG machine, and it worked like a charm. Choosing the right welding process can make a world of difference.

Duty Cycle

Duty cycle refers to how long a welding machine can operate at its maximum amperage within a 10-minute period before needing to cool down. If you’re doing short bursts of work, a machine with a lower duty cycle may suffice. But you’ll need a machine with a higher duty cycle for longer, more consistent work.

Back in the day, I was working on a large stainless steel pipe welding project. I chose a machine with a lower duty cycle, thinking it wouldn’t matter much. I ended up spending more time letting it cool down than actually welding. Lesson learned!

Amperage

The thickness of the stainless steel you’re welding will determine the amperage you need. I have worked with different thicknesses of stainless steel, and I can tell you, the right amperage is critical for a successful weld.

A low-amperage TIG machine might be suitable for dealing with thin sheets. However, you may require a MIG machine with a higher amperage for thicker materials. Don’t forget, too much heat can warp thin material, while too little won’t penetrate thicker ones. Balance is key!

Accessories

Lastly, let’s talk about accessories. Believe it or not, the right accessories can improve your welding experience tremendously. Good quality welding gloves and a helmet can keep you safe. The right welding rods can make a huge difference in the quality of your welds. And using a good quality tungsten for your TIG machine or the right wire for your MIG machine can significantly improve your stainless steel welding results.

Groove and Fillet Welding Positions

Regarding groove and fillet welds, the welding positions differentiate between flat, horizontal, vertical, and overhead positions. This helps us understand the appropriate technique, metal arc positioning, and the best welding rod type.

Pipe and Plate Welding Positions

The chart also distinguishes between pipe welding positions and plate welding positions. Pipe welding requires working around a fixed pipe in positions that may include vertical (uphill or downhill) and horizontal. In contrast, plate welding often takes place in a flat or horizontal welding position.

1G/1F/PA Position (Flat)

In my early days of welding, starting with the 1G position was a relief. The workpiece lays flat, and the weld runs along a horizontal axis, offering a comfortable position. But don’t be fooled; mastering the flat position requires keen attention to detail and the right balance of speed and angle.

The 1G or flat position is often the first step in any welder’s journey. The position lets the welder comfortably sit or stand while executing the weld on a horizontal plane. For newbies, it may take a few weeks to master, but patience is essential here.

Focus on consistency in your bead size and watch your travel speed. Going too fast or too slow can result in weak welds.

Regarding equipment, standard personal protective gear and a basic welding machine with suitable welding rods are enough to get started.

2G/PC Position (Horizontal)

The 2G position presents a bit more challenge. Here, the workpiece is vertical, but you weld on the top side of the joint, moving horizontally. It’s a tricky transition from 1G, but you’ll find your rhythm with practice.

The 2G position, where the joint is vertical, and the weld is performed horizontally, introduces a new level of complexity. On average, getting comfortable with this position might take a couple of months of practice.

It’s all about maintaining a steady hand and a consistent pace. Make sure to deposit enough metal at the start of the weld to prevent the formation of undercut.

As for equipment, besides the regular welding gear, some welders prefer to use a pipe stand for support when they start with 2G welding.

2F/PB Position (Horizontal)

The 2F position is a fillet weld where the workpiece is positioned horizontally. When I was apprenticing, this position was my nemesis. It’s easy to start fast and end up with inconsistent welds. But once you master this, the rest feel like a piece of cake!

The 2F position is a fillet weld with the workpiece positioned horizontally. This position can take several weeks to months to master, requiring a unique blend of control and consistency.

Ensure to maintain the correct work angle and hold a short arc length.

No additional equipment is required for this position, but a work clamp might help steady the workpiece.

3G Uphill/PF Position (Vertical)

Now, this is where things get more challenging. The 3G position requires vertical uphill welding, moving the welding rod upwards. The metal’s heat pulls the weld downward, which taught me an important lesson: working against gravity can be tough, but patience is key.

The 3G position is vertical uphill welding, which can take up to several months to master. This position is more challenging as it involves working against gravity.

The key is maintaining a short arc length and using a slight side-to-side or triangular weaving motion.

For this position, welders may want to invest in a welding lens with higher shade numbers since the weld pool tends to be brighter in vertical welding.

3G Downhill/PG Position (Vertical)

The 3G downhill position is the flip side, requiring a vertical downward movement. With gravity on your side, controlling the speed of the weld becomes the real challenge here. It’s an adrenaline rush, fighting to keep the speed in check!

Mastering this position might take as long as mastering uphill due to the challenge of controlling speed.

Maintain a slightly longer arc length and move quickly to prevent overheating and burn-through.

Equipment needs remain the same as with 3G Uphill.

4G/PE Position (Overhead)

Overhead welding or the 4G position can be a bit daunting initially. The workpiece is beneath you, and you weld from the underside. I found it intimidating back in the day, but once you overcome the fear and trust your skills, it becomes a routine affair.

This is a bit more challenging due to the need to deal with falling molten metal, which can take several months to get used to.

It’s all about getting comfortable with the overhead position. Keep your travel speed steady, and remember to clear away slag after each pass.

Regarding equipment, a welding helmet with an auto-darkening feature and a fire-resistant jacket is highly recommended for overhead welding.

4F/PD Position (Overhead)

The 4F position is an overhead fillet weld. I remember the day I first attempted it; weld spatter flying toward me was a real test of my resolve. But now, it’s just another day at the ‘office.’

Mastering this position can take a few months to a year, depending on how often you practice.

Start with a tight, consistent weave pattern and focus on control to prevent sagging or rollover of the weld metal.

Equipment requirements remain the same as with the 4G position.

5G Uphill Position (Vertical)

The 5G position was my first introduction to pipe welding. Here, the pipe is vertical, and the welder moves around it, welding uphill. It’s a game of skill, testing your hand-eye coordination and stamina.

This advanced welding position takes 4-8 months to excel at.

Good positioning of your body and staying steady are crucial. Consistently practice moving around the pipe while maintaining the right welding angle.

In addition to your standard welding kit, you’ll need pipe stands or pipe clamps to hold the pipe in a vertical position securely.

5G Downhill Position (Vertical)

Like 5G uphill, the 5G downhill position involves moving around a vertically fixed pipe, but this time you’re welding downwards. It’s a swift dance around the pipe, simultaneously controlling your speed and battling gravity.

Learn to control your speed. Gravity will tend to speed up your progress since you’re welding downhill. Also, ensure to control the puddle size for even welds.

Your basic welding kit and pipe clamps or stands will serve you well here.

6G Uphill/Downhill Position

The 6G position was my final hurdle in pipe welding. With the pipe fixed at a 45-degree angle, welding involves moving both around and along. It’s a true test of a welder’s skill, testing your ability to adapt and adjust to the different angles and positions.

It’s all about maintaining the right body positioning and movement while adapting to the changing angles. Keep practicing different transitions between welding positions. Along with your standard welding equipment, adjustable pipe stands will be beneficial to achieve and maintain the 45-degree angle.

6GR Test

The 6GR test is a step up from the 6G position. It has an additional ring restriction that simulates field conditions, making the task even more challenging. The day I passed my 6GR test was one of my proudest moments as a welder.

Practice with different pipe diameters and thicknesses to adapt to the varying field conditions you might encounter. Also, practicing under a mentor or experienced welder can provide valuable feedback.

The standard welding kit remains essential. In addition, you’ll need a practice setup that includes a ring for restriction to simulate the field conditions of the 6GR test.

This is an expert-level position skill that will take 6-12 months, plus additional time for test preparation.

Welding Tank Size Chart

Below is a table listing the most common welding tank sizes and their respective volumes. This can be used as a reliable tank chart for your projects.

The welding time in the table above is based on a standard consumption of 20 cf per hour.

Remember, these welding times are approximate and depend on your exact flow rate and the efficiency of your welding process. For instance, more experienced welders who can maintain a consistent bead with less stop/start action will typically use less gas compared to someone still perfecting their technique.

Types of Gas Bottles for Welding

Welding requires different types of gases, and knowing which to use can be just as important as understanding cylinder sizes. Let’s explore the most commonly used gases:

Argon

Argon is primarily used in TIG welding and MIG welding aluminum. I remember when I first tried out MIG welding and found that using pure Argon gave me a much smoother and cleaner weld than other gases.

CO2

CO2 is the cheapest welding gases and provides deep penetration, which is excellent for welding thick steel. However, it may result in a rougher weld than Argon or an Argon/CO2 blend.

Argon/CO2 Blend

This is a popular gas blend, especially for MIG welding steel. I’ve found that using a 75% Argon / 25% CO2 blend gives me excellent control over the weld and results in less spatter than pure CO2.

Popular Welding Tank Sizes

40 cf

The 40 cf size is quite popular, especially among hobbyists and DIY enthusiasts due to its portability. It’s great for your small projects around the house or garage.

80 cf

The 80 cf cylinder size is a middle-ground option. It offers more gas than a 40 cf tank while maintaining a reasonable size and weight. It’s ideal for medium-sized projects.

125 cf

The 125 cf cylinder is an excellent choice for professional welders or for those handling larger projects. I’ve used this size when I’ve had long, continuous welding jobs, which has served me well.

Welding Tank Material: Steel vs Aluminum

When it comes to the material of the welding tank, you have two main options: steel or aluminum. Steel tanks are often cheaper and more robust but are heavier and more prone to rust. On the other hand, aluminum tanks are lightweight and rust-resistant but more expensive.

Personally, I prefer aluminum tanks due to their longevity and ease of transport.

Steel Tanks

Steel tanks are incredibly durable, making them a popular choice in various industries, including welding. Because steel is robust and resistant to puncture, so it provides extra safety when dealing with pressurized gases. This strength also means that steel tanks are more likely to stand up to the rigors of a busy work environment or a crowded workshop.

One time, my steel tank had a minor mishap, falling over in my truck bed. It took the fall without a dent, a testament to its durability.

Steel tanks, however, have a couple of significant downsides. The first one is their weight. Because steel is much heavier than aluminum, steel gas cylinders can be more difficult to transport and maneuver. Depending on the cylinder’s size, this could lead to strain or injury.

The second downside is susceptibility to rust. Over time, exposure to moisture can cause a steel tank to rust. While this doesn’t necessarily compromise the tank’s ability to hold gas, it can make it look old and uncared for. More importantly, it could lead to a rough surface that might injure hands or snag on other materials.

Aluminum Tanks

Aluminum tanks, on the other hand, are known for being lighter than their steel counterparts. This weight difference can make a big difference when transporting and maneuvering the tank, particularly for DIY welders who might not have access to equipment like gas cylinder hand trucks.

I once replaced my steel tanks with aluminum ones and noticed how much easier it was to move around my shop. This ease of movement can be vital for those with back problems or other physical limitations.

Another significant advantage of aluminum is its rust resistance. Unlike steel, aluminum doesn’t rust when exposed to moisture, making it a more attractive option for those living in damp climates or those who want to maintain a clean, professional appearance in their workshops.

One potential downside of aluminum tanks is that they are generally more expensive than steel ones. However, when you consider the benefits – ease of transport, resistance to rust – it could be a worthwhile investment, especially if you plan on using your welding gas tanks for a long time.

How Long Does a Welding Tank Gas Bottle Last

The length of time a welding gas bottle will last you depends on several factors. These include the type of welding process you’re using (MIG, TIG, etc.), the gas flow rate, the gas cylinder size, and the efficiency of your welding technique.

Each welding process requires a different flow rate, typically measured in cubic feet per hour (cfh). For example, MIG welding generally requires a flow rate between 15 and 25 cfh, while TIG welding might require 10-15 cfh. The higher the flow rate, the faster you use your gas.

The gas cylinder size you’re using will also play a crucial role. Larger cylinders hold more gas, so they’ll last longer. For instance, with a flow rate of 20 cfh, a 125 cf tank would give you approximately 6.25 hours of welding time. On the other hand, a smaller 40 cf tank would provide just 2 hours at the same flow rate.

However, these figures assume continuous welding, which we all know is not how welding always works. Your gas may last significantly longer with stops and starts, set-up times, and breaks. For example, a day of intermittent welding might see a 125 cf tank lasting several days, or even a week, depending on the specific welding conditions.

How Much Gas Do I Need as a DIY Welder?

As a DIY welder, the amount of gas you’ll need will largely depend on your specific welding projects. Factors to consider include the project size, the welding process you’re using, and how often you weld.

Small projects and infrequent welding sessions may only require a smaller gas cylinder, such as a 20 or 40 cf tank. These tanks are also more portable and easier to handle, making them an excellent choice for DIY welders with limited workspace.

On the other hand, if you’re undertaking larger projects or welding more frequently, a bigger tank, such as an 80 or 125 cf cylinder, is a better choice. Although these tanks are larger and heavier, they provide more gas, which means fewer trips to the refill station.

The type of welding you do also plays a role. MIG and TIG welding, for example, generally require different gas flow rates, which will affect how quickly you go through your gas. As a rule of thumb, a higher flow rate or extended welding time will require more gas.

Conclusion

Knowing your cylinder sizes and gases is crucial for efficiency, cost-effectiveness, and safety. By understanding the specifications and available sizes of welding gas cylinders, you can tailor your welding setup to fit your needs, whether for a DIY project or industrial welding jobs.

You will likely also need an oxy-acetylene tank for your cutting needs.

The tables below show the recommended welding helmet lens shade number based on the type of welding and your amperage range. Protecting your eyes is crucial: you should never start welding with insufficient lenses.

Each process generates different levels of radiation, requiring specific shade recommendations.

Stick Welding

Stick welding uses a consumable electrode, and the arc generates moderate to high light radiation levels, depending on the amperage used.

MIG Welding

MIG processes produces moderate levels of light radiation, requiring lens shades in the mid-range.

TIG Welding

TIG welding produces more light radiation than the other processes, and you will have to choose a darker lens than the other alternatives.

Flux Core Welding

FCAW generates moderate to high levels of light radiation, with higher amperage producing brighter arcs.

Plasma Cutting

This process uses a constricted, high-velocity ionized gas jet to cut through metal. PAC generates moderate to high light levels, depending on the amperage used.

Welding Lens Shade Specifications

Welding lens shade specifications are crucial in selecting the appropriate eye protection during welding processes. Lens shades, ranging from 4 to 14, offer varying visible light transmission levels, infrared, and ultraviolet protection. These specifications ensure your eyes are shielded from harmful radiation, tailored to the welding process and amperage used.

Welding lenses are made of specialized materials that absorb or reflect specific wavelengths of light. The shade number corresponds to the level of protection provided, with higher numbers offering greater filtration and darker lenses.

Higher amperage generally produces brighter arcs and requires darker lens shades.

ANSI Z49.1:2012 offers detailed advice on which welding lens to use under numerous circumstances.

How to Select the Correct Lens Shade

Select the correct welding process and amperage range based on your project and material thickness. This gives you a good starting point using the tables above.

You should select a lens that is too dark to see the weld zone, and incrementally go to a lighter shade until you can see the weld zone without going below the minimum. This is the safest option to avoid going too light from the start.

You will have personal preferences for lens shades due to differences in vision, sensitivity, and comfort. Test various shades within the recommended range to find the most suitable option.

Auto-darkening helmets automatically adjust the lens shade based on the detected arc brightness.

Despite the stereotype that we’re pretty grubby guys, welders pay a lot of attention to our clothes. We’re probably some of the only people who still starch our clothes in the 21^st century. Starching is the process of adding starch to clothing to repel dirt and wrinkles.

Welders starch their clothes because of the unique properties of fire-resistant welding clothes. Starching helps repel dirt and makes clothing more resistant to wear and tear. It also helps expensive welding clothes last longer.

Being a welder doesn’t require just thinking about machinery—you must also think about your clothes. Here is what you need to know about starching your clothes as a welder.

Why Do Welders Starch Their Clothes?

There are a few reasons why welders starch their clothes.

1. Starching Makes Clothing More Resistant to Dirt

People used to starch their clothes in the days before washing machines, when doing laundry was a much bigger chore than it is now, because starching makes clothing more resistant to dirt. The starch creates an extra layer of protection that acts as a barrier in front of the fabric. Welding is very dirty, with lots of soot, ash, and debris flying around. Starch makes it less likely for the dirt to stick and easier to clean up any mess that does happen.

2. Starching Clothing Makes It More Fire-Resistant

Another reason starching was popular back in the day is that in the times of candlelight, clothing catching on fire was a much bigger problem than it is now. Guess who has to worry about clothing catching on fire today? That’s right, welders.

Starching creates a stiff outer layer of protection that is naturally flame resistant. While it won’t make a regular shirt magically resistant to a whole blaze, it can prevent sparks and hot slag from burning through your shirt and burning your skin. Even if your welding uniform is already fire-resistant, starching can add an extra layer of protection.

3. Starching Makes Welding Clothing Last Longer

Welding clothing that will protect you from heat, fire, and debris can get expensive. Ideally, you want your clothing to last for a long time, so you don’t need to pay through the nose to replace your pants in just a few months. 

Starching your welding clothes helps them last longer because you make the clothing more resistant to burns, stains, and other damage that could shorten its lifespan. Starching ultimately saves you money.

Which Welding Clothes Need to Be Starched?

You need to starch if you have 100% denim or cotton welding clothes. Starching garments made out of natural fibers will create an extra protective layer. 

While you don’t need to starch fire-resistant clothing because it is already protected thanks to the manufacturer coating, you can use starch if it makes you feel better to have an extra layer of protection.

You can’t starch most synthetic fabrics, such as polyester, because the starch doesn’t stick to those fibers.

How to Starch Welding Clothes

Here is a step-by-step guide to starching your welding clothes.

1. Gather Your Supplies

You will need a spray bottle; starch, such as Sta-Flo; hangers with swivel heads, and a press. 

2. Set Up Your Starching Area

Hang your clothes on the hangers. Ensure you’re in an area where you can clean up easily, such as a tub or outside. 

Put the starch in the spray bottle. Prime the spray bottle with a few pumps so it’s ready to go.

3. Spray the Clothes with Your Starch

Take your spray bottle and spray your clothing with the starch, making sure to cover every bit. Turn the handle around so you get the front and back of your clothes.

Let your clothes dry overnight.

4. Press Your Starched Clothes

Pressing seals the starched layer. Once your clothes are dry, use your steam press to create the crease. You can use a hand iron, but it will take much longer.

What Other Protective Equipment Is Required When Welding?

Starching your welding clothes gives you an additional layer of protection; however, starching alone is not enough protection during welding. You need plenty of other protective equipment, such as:

• Safety glasses
• A welding helmet
• Sturdy boots
• Heavy-duty gloves
• Earplugs

My complete guide to the protective equipment you should have before starting out.

Final Thoughts

Many welders starch their clothes, not because they care about their appearance while welding but because it is practical. Starching helps welding clothes last longer because it makes them more resistant to dirt, sparks, and other job hazards. Starching is also relatively easy at home and a great way to upgrade cotton or denim clothing.

The generator must have sufficient power output (measured in watts) to match the welder’s input requirements. Choose an appropriately-sized generator with a steady output and consider possible voltage fluctuations, which can affect welding performance and consistency.

When you weld, you can’t always rely on having access to your workshop and a great power supply. Sometimes, you must go weld outside, whether an amateur or a professional. Or your workshop may have a strange setup and make regular wall outlets inaccessible. Regardless, some welders prefer to run their welding machines off of generators.

You need to know here before plugging your welder into a generator.

Can You Run a Welder Off a Generator?

Yes, you can run a welder off a generator, but it must have sufficient power output (measured in watts) to match the welder’s input requirements. Choose an appropriately-sized generator with a steady output and consider possible voltage fluctuations, which can affect welding performance and consistency.

Welders need power to operate. Most arc welding machines use an electrical power source to create the arc. Ideally, you would run a welder by plugging it into a wall socket, which is the most reliable way to deliver power.

However, there are situations when a wall source of power is unavailable.

• Maybe the power is out, and you urgently need to weld something.
• Maybe you are working on a welding project outdoors, far away from a power source.
• Maybe the wall socket in your workshop is just too far away.

In those situations, you can use a generator.

Which Welders Can Run Off a Generator?

You do need to watch out for a few things before plugging in your generator. Some welders don’t work well with generators and will get damaged. 

The best welders for running off a generator are transformer-powered welders. Transformer-powered welders have a built-in transformer that converts the power source into the right current for the welder, usually a low alternating current. 

However, many modern manufacturers are switching to inverter welders. Inverter welders use complicated electronics to power the welding machine. Inverter welders are smaller, sleeker, and more efficient because the bulky transformer was removed. Without the transformer, they rely on the input power tailored to the welder’s needs. That means the inverted welder is much more sensitive to fluctuations in power, which are more common with a generator.

You can still use some inverter welders with generators. However, make sure that you are choosing a model designed for use with a generator.

I personally use the DuoMax Generator and am very happy with its performance:

The Disadvantages of Using a Generator as a Power Source

The advantages of using a generator as a power source are immediately visible. Generators are portable and mobile, ensuring that you can work anywhere.

However, they also have a few disadvantages. You should be aware of them before plugging any machinery into the generator.

1. Generators Have Dirty Power

When we use the term dirty power referring to a generator, we’re not talking about the exhaust that a generator produces (although the pollution is another disadvantage we’ll get to later). We’re referring to the quality of the electrical output.

Sensitive electronics prefer to get their power via an electrical source that produces an AC current as close to a perfect sine wave as possible. Power from an electrical main manages to achieve this goal. 

However, generators deliver dirty power, or electrical waves that fluctuate. Generator electricity is not as stable as you would get from a wall socket, with periodic surges, peaks, and troughs. Although the average voltage as you run it may be the same, the spikes in power affect the quality of the electricity.

Generator specifications often give a THD or Total Harmonic Distortion, which describes how close the power wave is to a perfect sine wave. Generators with a THD rate of 6% or less produce ‘cleaner’ power and are better suited for welding machines.

2. Generators Could Damage Your Equipment

Because generators deliver this “dirty” power, your welder could experience a sudden surge in electricity when it’s plugged into a generator. Surges damage sensitive electronic parts such as capacitors, which are the parts that replace a transformer in an inverted generator. Once you damage these internal electronics, you have to get a new welder.

3. Generators Are Not Pleasant to Work Near

This might be less important than the prospect of damaging a welder that costs hundreds of dollars, but generators are not always the most pleasant items to work with. They make a lot of noise, smell bad, and generate a lot of pollution that works its way into your lungs. Welding is already a dirty job; you don’t want to add to it with generators if you don’t have to.

What Size Generator Do I Need?

Choosing the right size is important if you need to run your welder with a generator. The answer depends on the max output of your welder. The bigger the output, the bigger the generator you will need to power it.

If your welder only goes up to 130 amps, you only need a generator of about 7 kva. However, if it goes up to 250 amps, you should get a much bigger generator of 15+kva.

These are just guidelines, so look for generator size charts when shopping for one to power your welder.

Tips and Mistakes to Avoid

When you’re running your welder off a generator, here are some tips to keep in mind.

• Always ground your generator. Grounding completes the circuit and prevents you from getting shocked.
• Get a quality generator. Make sure it has low Total Harmonic Distortion, lessening the surge risk. Your generator is not the area where you want to save money.
• Regularly maintain your generator. Make sure that parts such as the power extension leads, fuel lines, and cables are in good condition with no bends or tears.

Final Thoughts

When using a welding machine, it’s almost always better to connect it to a main power supply. Sometimes, you have to use a generator. 

When connecting a welder to a generator, it’s better to use a bulky transformer than an inverter welder. If you have to use an inverter welder with a generator, make sure the generator has low Total Harmonic Distortion and is the right size to power your machine.

For a hobby welder using less than 240 amps and less than 50 ft in combined cable length, a 1 gauge welding lead is sufficient. If you exceed these constraints or are doing more advanced welding, read through this guide to find a welding cable size that suits your needs.

A welding lead or cable is an all-important part of your welding setup. It is the object that connects your welding machine to your electrode, making sure that you actually have the power you need to weld. Without your welding leads, you would try turning on your welder, and only dust would come out, not a spark.

Choosing the right size welding leads is important for your safety and the effectiveness of the machine you are working with. A few factors influence the size of welding leads you need, including amperage, duty cycle, and other things. When in doubt, consult a sizing chart.

Here is your guide to choosing the right welding leads for your set-up.

What Is a Welding Cable?

Before we talk about the size of the welding cable you need, we should probably establish what a welding cable is in the first place.

Welding cables and leads are the same things. They are important parts of your arc welding setup. Welding leads are copper wires that connect the arc welding machine with your electrodes. They deliver the electrical power from your machine to the electrode, starting the arc. 

Welding cables are specially designed to handle large quantities of electricity. Almost all of them contain copper, one of the best electrical conductors. However, different sizes of welding cables are designed for different electrical capacities. Get a too small cable that might burn or cause an incident when you try to surge a high amperage through it. That’s why choosing the right size welding cable is important.

Types of Welding Cables

There are a few types of welding cables you will encounter when you head to the shop to pick some out. You can distinguish them according to a few of the following factors.

1. Core Material

The core of a welding cable is a strand of hundreds of thin wires that are very flexible and conduct electricity. Most welding cables use a copper core because this metal is the best conductor of electricity. Some use aluminum because it is lighter and more affordable, but the diameter has to be larger to fit more strands of wire.

2. Insulation Material

Welding cables also differ in terms of the material used to insulate them. EPDM and neoprene are two types of synthetic rubbers that are popular insulators because they are very flexible. PVC is less flexible but tougher and less likely to tear even when exposed to rough environments.

3. Purpose

Finally, the welding cables you see in stores differ depending on their purposes. Most are designed to connect the arc welding machine with the electrodes. However, some welding cables are actually grounding cables designed to prevent electric shock. Make sure you get the right type of welding cable for your purpose.

AWG Welding Sizes

AWG or American Wire Guide describes the size of welding cables. You will often see welding cable sizes in terms of their AWG Guage, which has the following specifications:

Welding Cable Size Chart

This table shows the recommended welding cable size in AWG for different lengths (electrode and work cable combined) for different current draws:

What Size Welding Leads Do I Need for a Duty Cycle Welder?

Every single welding machine has a duty cycle. The duty cycle describes how long the welding machine can be operational in 10 minutes without overheating. The duty cycle changes with a few factors, including the amperage of the welding machine.

As a rule of thumb, the longer the duty cycle, the thicker welding leads you will need. If the duty cycle is longer, more power will be coursing through the welding cable. You need a welding cable that will stand up to that consistent amperage. 

For a higher duty cycle (this will depend on your machine and the type of welding you are doing), choose a thicker welding lead, such as 2/0 or 3/0 cable size.

What Size Welding Leads Do I Need for an Amperage Welder?

Every welding machine also has its own amperage. The amperage of the welder machine describes how much current flows through the circuit. Most welders can adjust amperages along a range. 

If you know that you will be working on projects along the higher end of the range of your welder’s amperage, you need to get bigger welding leads with a higher ampacity. The ampacity is the current that a cable can carry without causing damage. 

The biggest potential damage comes from the heat that electricity generates. If your cable has a low ampacity, the electrical current will burn through the cable. At best, you will need to stop work and replace your cables. At worst, you will cause a workshop fire.

Calculating ampacity on your own is difficult because you have to look at the size, circuit length, and other factors. That is why you should look at the cable size chart. These charts tell you which cable you should get based on the maximum amperage and duty cycle. They are very useful tools to have when you’re buying welding cables.

What Length Welding Leads Do I Need?

Your welding leads should be long enough to reach your workspace from the welding machine. I recommend selecting at least 15 feet of welding lead length to give yourself plenty of room to maneuver.

However, the length of the welding leads also impacts the current capacity.

When choosing your welding cables, look at the length of the welding setup, from your grounding cable to the electrode holder. Then, look at the chart to see the cable size you will need. Choose the length of the welding leads that will fit within the range recommended for your cable size.

For example, if you are operating at a 20% duty cycle and want to use a size eight cable, you must ensure the setup is below 50 feet. You will need a shorter welding lead than if you go a size up and choose a size four welding cable.

Final Thoughts

Choosing the right size welding cables is important because you don’t want your machine to work improperly or catch fire. Luckily, a standardized size chart using American wire gauge sizing tells you which size to get according to duty cycle, amperage, and length.

Welder caps help protect welders’ heads, necks, and ears from flying sparks. They have a soft peaked demand and ear flaps to protect the welder. Welder caps have become trendy, so you can buy one, but one of the best ways to ensure you have a quality cap is to make one yourself.

Here is everything you need to know about making a welder cap.

Why Do Welders Wear Caps?

Not all welders wear caps anymore, but many still do. Many welders wear welder caps to protect their faces and heads from flying sparks, slag, and other debris. When welders wear these caps, the brim is snug and low across the forehead and covers the top of the ears. Some welders even adjust the caps according to which position they’re welding in to allow the cap to protect them maximally.

There is a story about the history of welder caps. The story goes that a widow made the cap for her husband’s former colleagues out of gratitude because they raised money for her in her time of need. Whether this story is true or not, it shows how important welder caps are to welders.

Design Features of a Welder’s Cap

A welder’s cap is not the same as any other cap, such as a baseball cap. Here are some of the design features that set it apart from other headgear.

• A high crown. A properly fitting welding cap will have the crown protruding high above the head, which looks a little strange but is necessary for the rest of the cap to fit properly.
• A soft brim. The welding cap has a low, rounded brim or bill. The bill has to be soft to fit comfortably under welding helmets or face shields.
• Low band. The band pulled low helps protect the welder’s ears.
• 100% cotton material. Welding caps have to be made of cotton or other natural material. Natural materials are more breathable than synthetics, which is important in the often sweltering conditions in welding workshops. Plus, synthetic fibers are more prone to melting when exposed to heat—not an ideal combination when you are working around flames.

These design features are making the welder’s cap a popular style accessory now. However, the purpose of the design features is not to create a good-looking cap—these design features are in place just to protect the welders.

How to Make a Welder’s Cap

If you want to be certain that your welder’s cap is the best quality, you can make your own. Here is a step-by-step guide to this process.

1. Gather and Prepare Your Materials

You will need an outer cloth, inner cloth for lining, interfacing, fabric shears, a fabric pen, a needle, thread, and your pattern. You can find welder’s cap patterns online. Your fabric should be cotton or another breathable natural material.

2. Cut Out Your Pieces

First, cut out the pieces of the pattern (make sure that you size the pattern to your head or the head of the person you are making the welder’s cap for). 

Then, using the pattern to trace the size and shape, cut out pieces from the fabric. These pieces will make up your welder’s cap. 

During this step, you should also mark up your fabric pieces according to the pattern. This will make it a lot easier to put the pattern together later.

3. Prepare Your Interfacing

Interfacing is adding a layer to your fabric to make it stiffer and sturdier. 

Place your pieces of cloth on a board. Lay a large sheet of interfacing over them. Press the interfacing into the fabric with an iron. Once the interfacing is set, you can cut out the edges to match the pieces.

You can also cut the interfacing to match the pieces and then iron it, but this way is faster.

4. Sew the Cap

Locate the pieces that make up the side of the cap. Sew the tops of the pieces together (outer layer to outer layer, inner lining to inner lining).

Connect your front and back pieces as well, sewing just one side and leaving the rest open.

Pin the pieces together to create the dome shape. Sew the fabric together. Make sure you only sew outer pieces to outer pieces and liner pieces to liner pieces. 

5. Make the Bill

Now, you can make the bill. Pin the two sides of the fabric together, then stitch into place. Turn the fabric inside out, then sew the edge again to get a crisp edge.

6. Make the Headband

Now it’s time to make the headband, or the piece that goes directly around your head. Join the pieces in a ring that fits around your head and sew the edges together.

Attach the band to the bill. Pin it in place and sew all around. You should now have a circle with an attached bill. Smooth the band flat.

7. Attach the Crown

Finally, it’s time to finish assembling your cap. Pin the outer shell of the fabric to the band and sew all around. Turn the cap inside out, then attach the lining—you will need plenty of pins at this step. 

Make sure there are no loose pieces floating around, and now you have a welder’s cap!

Can You Buy Welders’ Caps?

If you’re a busy welder working 60-hour weeks, you might not have time to sew an entire welder’s cap from scratch. In that case, you can buy welders’ caps. Just make sure that you are buying from a retailer that specializes in work gear, not just a fashionable cap.

Final Thoughts

Welders’ caps help protect your ears and head from sparks. Buy one or make your own today!

Vulcan welders are manufactured by Canary Electrical PVT Limited. Unlike some of the other more popular welding brands, Canary Electrical is not based in the United States. Instead, this company comes from India, which is still one of the world’s top manufacturing centers.

Here is what you need to know about Vulcan welders.

Who Makes Vulcan Welders?

It takes some digging to find out more information about Vulcan welders. The Vulcan welding brand belongs to the parent company Vulcan Ltd. Vulcan Ltd. is part of an even bigger company. So, Canary Electrical PVT Limited is the company that is behind Vulcan welders.

Canary Electrical is a manufacturer based in Morbi, which is a town in the state of Gujarat, India. This company is a large manufacturer and exporter of welding machines, including the Vulcan line.

The History of Vulcan Welders

Vulcan welders don’t have as long and storied a history as some other brands you may be familiar with, such as Hobart, Miller Electric, and Lincoln Electric. However, there are still several decades of experience behind these products.

The company that produces Vulcan welders, Canary Electrical, was founded in 1980. It specializes in manufacturing welding machines such as TIG welding machines, AC/DC ARC welding machines, and inverter-based welding machines. Canary Electrical is not limited to the Indian market. It is a prominent exporter of welding machines, mostly to other South Asian markets but also to the United States.

Finding information about the history of the Vulcan brand specifically is a bit more difficult. However, we can assume that the Vulcan brand started around the same time as Canary Electrical was founded. Canary Electrical has several decades of experience making the latest cutting-edge welding machines using innovative technology, and the company input much of its knowledge into its Vulcan brand.

What Makes Vulcan Welders Different?

There are a few things that make Vulcan welders different from similar models made by other companies.

• The price point. Vulcan welders are a lot more affordable than similar welding machines from other companies, although they still cost several hundred dollars. This makes them more accessible to hobbyists, but some professionals are suspicious of the low prices.
• Inverter technology. Inverter technology in welding is a new technology that converts AC voltage to usable voltage. Previous machines used transformers, which are bulky and expensive to produce. Since many Vulcan models use inverter technology, the cost of production goes down, and the machines are easier to maneuver.
• Functionality under difficult conditions. Canary Electrical says that it wanted to make machines that people could use in all conditions, including dusty, dirty conditions. Many welding workshops are not exactly the most pristine places in the world, so this functionality is definitely necessary. Thanks to technology such as auto-sensing, low heat distortion, and more, Vulcan welders are great even for outdoor use.

Are Vulcan Welders Any Good?

Reviews are a bit mixed about whether or not Vulcan welders are any good. The machines have certain advantages, including their durability, strength, and resilience to conditions such as wind and debris. They are also lightweight and relatively affordable, making them more versatile than similar welders. People particularly praise their TIG welders, which are often used in professional settings.

However, other people are skeptical due to the lack of information available online about the company. There also isn’t a lot of transparency about parts replacement and warranty information. Tradesmen who rely on welders to make a living are understandably reluctant to invest in a machine they won’t be able to get fixed if something happens.

The final verdict is that Vulcan welders are good, especially for hobbyists, because:

1. They are lightweight.
2. They are easy to use and maintain.
3. The short warranty and lack of parts replacement don’t matter as much for people who use welders sporadically.

Are Vulcan Welders Made in the USA?

No, Vulcan welders are made in India.

This doesn’t mean the manufacturing is not high-quality. However, there are a few reasons why you might want to buy from US-based manufacturing besides supporting American jobs. US manufacturers are more responsive to customer service and are more likely to have replacement parts available near you. Reviewers indicate that servicing and replacing Vulcan welders in the U.S. is a bit tough at the moment.

Final Thoughts

Vulcan welders are made in India by Canary Electric. They are solid welders, but many people still prefer local companies such as Hobart.

The post Who Makes Vulcan Welders? appeared first on Beginner Welding Guide.

Hobart welders come from the Hobart Brothers company. Besides welders, they also manufacture filler metals and electrodes.

If you’ve ever wondered about the history behind the name on your welding machine, or you’re researching different companies to decide which ones to buy, here is what you need to know about Hobart welders.

Who Makes Hobart Welders?

Hobart welders are manufactured by Hobart Brothers LLC, a prominent manufacturing company. In 1996, Hobart was actually acquired by Illinois Tool Works, so technically, Illinois Tool Works is the company that manufactures these welders. However, ITW chose to keep the Hobart name, in part because of the quality associated with it for decades.

The History of Hobart Welders

Hobart welders have a long, illustrious history that actually predates modern welding. 

Hobart Brothers, the company that manufactures Hobart welders to this day despite its merger with Illinois Tool Works, was founded in 1917. That is over a century of history behind your welder! 

Hobart started out as a family company run by C.C. Hobart, his wife, and three sons. It didn’t start out as a welding company. Instead, C.C. Hobart made many different metal objects, including generators, air compressors, and even furniture. In 1925, Hobart Brothers made its first welder, and the rest, as they say, was history.

By the mid-20^th century, Hobart Brothers was a welding powerhouse. The company powered much of the World War II weapons production effort and was even rewarded for its efforts. It had contracts with prominent companies such as American Airlines. 

The company even started its own training academy, the Hobart Institute of Welding Technology, in 1930. In the decades since, thousands of welders have been educated thanks to this non-profit academy. The efforts were crucial in the early days when few people were trained in welding. They are just as important today when welding is a ticket toward a secure trade for many young people.

One other impressive fact about Hobart Brothers is that the company remained family-owned and operated until 1996 when it was purchased by Illinois Tool Works. That family reputation is part of why the Hobart brand survived for so long.

What Makes Hobart Welders Different?

There are a few features that make Hobart welders distinct from other welding machines. They include:

• Better wire feed speed control. Hobart welders offer infinite control over the feed wire speed, which is very valuable when you are using a system that automatically feeds filler wire.
• Simpler controls. The simpler controls mean Hobart welders are more accessible for beginner welders.
• More affordability. Hobart welders are known as some of the best welders for hobbyists. That’s because they’re easy to use and won’t cost a pretty penny to bring to your workshop without compromising on quality.

Are Hobart Welders Any Good?

Hobart welders are some of the best welders you can find on the market today, especially if you are an amateur welder looking to scratch your DIY itch. 

Here are some of the reasons why Hobart welders are excellent.

1. They are very durable. Hobart welders come with sturdy parts that hold up to any wear and tear, which makes them last for a long time.
2. They are accessible for DIYers. Many welding machines are too complicated, large, or expensive for a DIY workshop. Hobart machines are perfect for amateur welders to use without compromising on quality.
3. They are more versatile. For example, Hobart MIG welders come with two plug-in options.
4. You can trust the company. Hobart machines come with a pretty long warranty, usually about three years, which makes me trust that the company will cover any damage.
5. Plenty of industries trust it. Hobart welders are popular in shipbuilding, the automotive industry, and many other industries. That means they’re good enough for my garage.

These are enough reasons to realize that Hobart welders are pretty good.

• Can Weld Up to 1/4" Mild Steel
• 20% Duty Cycle at 90 Amps
• 115V Supply Only
• Includes 10 ft MIG Gun and 10 ft Work Cable with Clamp

Are Hobart Welders Made in the USA?

Hobart Brothers is an American company that prides itself on making all of its welders in the United States. Most production happens in Troy, Ohio. Some Hobart welders are manufactured in Appleton, Wisconsin. Many people were worried that ITW would move production abroad, but it didn’t do so for the Hobart line.

Final Thoughts

Hobart welders are made by the Hobart Brothers company, a historical family-owned company. Now, Illinois Tool Works owns Hobart Brothers but kept the name, manufacturing practices such as manufacturing domestically, and quality people associated with Hobart.

Oxy acetylene tanks, including torches, are an important fuel source for welding machines. These tanks include oxygen and acetylene, a very hot fuel gas. The tanks contain two important gases that combine to create a hot fuel. Having enough oxy acetylene on hand ensures you can get the job done.

You should get the right size oxy acetylene tank to have enough fuel. Choosing the right tank can be overwhelming when you look at the range of sizes available. Think about the amount of gas you plan to use for your project and the space you have to store these volatile tanks.

Here is your complete guide to different sizes of oxy acetylene tanks.

What Size of Oxy Acetylene Tanks Are Available?

The sizing charts of oxy acetylene tanks differ from country to country. There are even different sizing conventions for the United States and Canada. 

There are ten different oxy acetylene tank sizes available in the United States. In order of increasing height, they are:

The shortest tank, according to the United States size chart, is the MC tank. This tank is 13.2 inches high and has a maximum capacity of 10 cubic feet of gas.

The largest tank is the 5 tank. This tank is 51 inches high and has a maximum capacity of 350 cubic feet of gas. Unless you are purchasing oxy acetylene tanks for a massive workshop or factory that relies on this gas to fuel welding torches, you will probably never need this much oxy acetylene. 

Just because a tank is the tallest or widest does not mean it has the biggest capacity. The tank with the biggest capacity is the WTL cylinder, which contains 390 cubic feet. Before buying a tank, you should carefully look at the dimensions and match them to the demands of your project. It’s not as simple as assuming that the tallest or widest will have the greatest gas capacity or necessarily be the best for you.

How Heavy Is an Oxy Acetylene Tank?

Besides the height and gas capacity, another important dimension to consider for the tank you are getting is the weight. 

How heavy an oxy acetylene tank is will depend on the size tank we are talking about. For example, the smallest tank will only weigh about 7 pounds. Meanwhile, the 5 tank weighs about 189 pounds.

The 5 tank is not the heaviest size of oxy acetylene tank you can get. The WK acetylene tank is shorter than the 5 tank but is the widest on the list. That makes it the heaviest, at a whopping 220 pounds. 

How Much Does a Tank of Oxy Acetylene Cost?

The cost of a tank of oxy acetylene will vary depending on the size you are getting. This makes sense because you will obviously pay more money to get more gas. 

Small tanks, such as the MC, only cost about $50. Most of the bigger tanks clock in at around $300. That is about six times the price of the small tanks, although you are getting much more gas per dollar.

An important question is how much a tank of oxy acetylene compares to other common fuel methods. A tank of oxy acetylene is less expensive than a similar amount of plasma fuel. Although a tank of oxy acetylene is more expensive than a tank of propane, it is also more efficient, so it will last longer.

How Much Oxy Acetylene Will You Use?

How much oxy acetylene you will use can help you determine how much you need to buy. You want enough oxy acetylene on hand to fuel your entire project; otherwise, you’ll be met with an empty tank mid-weld.

The answer to how much oxy acetylene you will use depends on a few factors, including:

1. The thickness of the metal
2. The intensity of the flame
3. The type of welding (heavy metals or emittive fluxes)

The flow is measured in liters per hour, or L/hr. The lowest is about 70 L/hr, while heavy-duty projects can have a flow of over 800 L/hr. Here is a table that can help you determine how much oxy acetylene you will use and which filters to use for your helmet.

Due to the many factors affecting oxy acetylene flow, it’s difficult to say how much oxy acetylene you will use. When in doubt, go to a supply store and explain what you are working on to the workers. They can give you personalized advice on what type and size of tank to get.

Another Factor Affecting Which Size Tank to Get – Storage Capacity

Obviously, when shopping for an oxy acetylene tank, you need to think about how much you are using for your project. Another factor is your storage capacity. Oxy acetylene is a very volatile gas. You must follow special procedures to store your tanks, including storing them upright with their valved caps screwed on tightly. Don’t get a tank so big you don’t have anywhere to store it in your workshop.

What Is Oxy Acetylene Used For?

Although oxy acetylene is a volatile fuel, its many uses make it a popular choice. Here are some of the many uses:

• Welding thin metals
• Torch welding
• Melting sturdy metals such as steel

Oxy acetylene works with different welding tools, including torches. It gives you more control over the heat, making it ideal for thinner metals. It produces a hotter flame than other gases, making it ideal for melting steel if you don’t have access to welding equipment more powerful than a torch.

Final Thoughts

If you have a welding torch, oxy acetylene is an important fuel source to have on hand. In the United States, this fuel comes in tanks of ten different sizes that differ in height, weight, and gas capacity.

When most people think about welding, they think about powerful machines welding massive metal sheets. However, welding is also a useful tool for welding thin, delicate pieces of metal. There are a few reasons why you may want to weld thin metal. Maybe you’re working in a factory that uses thin sheet metal or trying to make welding art at home. 

Welding thin metal comes with its own unique challenges. You can get around them by adjusting the welding angle, shielding gas, and other aspects of the welding job.

Whatever the reason you are tackling this challenge, here are the ways to successfully weld thin metal.

Why Is Welding Thin Metal Different?

If welding is a versatile, universal technique, you may wonder why you need a separate guide just to weld thin metals. These are metals just like any other. 

However, there are a few reasons why welding thin metals differs from welding thicker substances.

Thin metal is more sensitive to heat.

Welding works by melting the metal you are working with just enough to create material for a seam. With thin metals, it’s a lot easier to melt the metal all the way through if you’re not careful and don’t have enough control over the heat of your welding machine. That is called burn-through.

Many welders compensate for this by lowering the heat, but the joints will not be supple enough if you don’t use enough heat. Striking a balance between just enough heat and not enough is a delicate task, especially for beginners.

That is why welding thinner metals such as aluminum is much harder than welding thicker materials.

Choose the Best Welding Process for Thin Metals

There are several welding methods out there, including: 

• MIG welding
• TIG welding
• Stick welding

Of these methods, the best one for welding thin metals is MIG welding. This is the most common type of welding that people in manufacturing use for welding sheet metals, which are thin pieces of metal. You can also pulse when using MIG welding, lessening your burn-through risk.

Although TIG welding was designed for very thick pieces of metal, it is also a good choice for welding thin metals. TIG welding is more precise and gives you more control over the heat application. However, it is much harder to use for amateurs.

When working with very thin metals, skip stick welding. This method gives you the least control over the heat application and will most likely result in burn-throughs, splattering, and excessive slag formation.

Step-by-Step Guide to MIG Weld Thin Metals

MIG welding is the most common technique welders use for thin metals. Here are the steps you need to take for this process.

1. Choose the Right Shielding Gas

MIG welding works in tandem with the shielding gas, which prevents the weld from oxidizing. The shielding gas also affects the weld bead’s appearance. For thin metals, you want a weld bead that won’t produce a lot of spatter when it appears.

Use shielding gases that have high argon concentrations.

2. Choose the Right Filler Metal

The filler metal is the metal that melts into the weld and fills the gap between the two pieces. MIG welding automates feeding the filler, which makes your life as a welder easier. The material doesn’t matter as much as the form of the filler metal.

Ensure you use very thin wires when working with reedy, thin sheet metal.

3. Adjust Your Torch Angle

Changing the torch angle when MIG welding goes a long way to preventing burn-throughs. Make sure you adjust the angle to shorten the distance between the tip and the metal, no matter the welding position you work in. This will make the arc more stable, giving you more control over the weld and lessening the chance of burn-through.

4. Try Pulsing

Besides your regular MIG welding technique, you can also try pulsing when welding thin metals. When you pulse metals, you heat a small portion of the plates you are trying to join, then let the weld pool completely before filling in the joint. Although pulsing requires practice to master, it gives you more control over the energy output.

Although TIG welding was designed for thicker materials, you can use it to weld thin metals thanks to the extra control you get over the energy output. Here are the steps to follow.

1. Adjust to the Correct Amperage Settings

The first thing you need to do when TIG welding thin metals is to adjust the amperage settings. Lower the power setting and switch out the anodes to smaller ones. This lessens the energy output. You don’t need as much energy to melt thin metals anyway, and this way, you prevent burn-through. TIG welding lets you control the heat as you weld with a foot pedal, so take advantage of that.

2. Pick the Right Filler Metal (and Add It Properly)

TIG welding uses tungsten anodes to create the arc. For thin metals, experts recommend 0.020 and 0.040 thoriated anodes. Thoriated tungsten is alloyed with the metal thorium, which gives the anode more current distribution.

3. Use an Even, Fast Distribution

When TIG welding thin metals, avoid concentrating the heat in one place for too long. Stitch welding is the best technique, which uses a skip technique to apply a series of welds along a seam. This prevents you from applying too much heat in one place.

Final Thoughts

Welding thin metal is sometimes harder than welding massive chunks because the likelihood of burning through and damaging the base metal is much higher. For this welding challenge, use a welding method that gives you a lot of control, such as MIG or TIG welding, make sure you have the right electrodes and shielding gas, and adjust your technique.
