1. AlphaTIG 203Xi

AHP AlphaTIG 200X Welder
  • Advanced Inverter Technology
  • Lightweight and Portable
  • Impressive Duty Cycle
  • Dual Voltage Capability

What I like about this unit is the simple interface. Again, when you’re starting out, it’s about building confidence. And not getting overwhelmed with too many options. You can change the pulse settings of frequency and amperage.

It can use both 120V and 240V, depending on your availability. I found it very effective at welding carbon steel, aluminum and stainless steel.

This welder has a 60% duty cycle at 200 amps or a 100% duty cycle at 150 amps. This means you can weld for extremely long periods for fairly serious thickness materials.

It has a 3-year warranty on the welder but only 6 months on the foot pedals and spool guns. I noticed the copper in the ground clamp was weak and needed to be replaced relatively early.


  • Amperage Range: 20 to 200 Amps
  • Input Voltage: 120/240V
  • Duty Cycle: 35% at 200 Amps
  • Weight: 40 Pounds


  • Very simple interface
  • Amazing customer support
  • Welds both AC (aluminum) and DC (steel)


  • Expensive unit to start with
  • The duty cycle can be short if you’re doing a lot of welding

2. ESAB Mini-Arc 161

ESAB Rebel 215ic Welder
  • Pre-flow/post-flow adjustment
  • Five-handle roll cage industrial design
  • Ready to Weld Out of the Box

ESAB Mini-Arc 161 will get you acquainted with TIG on a budget.

This is great for someone wanting to learn and practice TIG welding.

I also feel that you will outgrow this machine quite quickly if you wish to continue learning. Unless you want to specialize in one specific type of welding. Say, mild steel pipes as an example, you may want the AlphaTIG Welder.

This welder is extremely lightweight at only 18 pounds and comes with a shoulder strap so you can move it around very easily. It operates on multiple voltages for flexibility. It has an amperage range of 5 to 160, so you can weld up to 1/4 inch thick material.

It doesn’t come with a TIG torch, so you must purchase one separately.

This brilliant little machine is portable and affordable, but you will likely outgrow it quickly and need to upgrade as you learn more.

TIG Welder Machine Requirements

Let me start by recalling my first encounter with TIG welding – a mixture of excitement and overwhelming choices. Several years and countless welding projects later, I’m here to share my experience and guide you through your TIG welding machine purchase. But before we proceed, a brief introduction to TIG welding for beginners is in order.

Tungsten Inert Gas (TIG) welding, or Gas Tungsten Arc Welding (GTAW), involves using a non-consumable tungsten electrode, filler metal, and an inert shielding gas. It’s known for its precision and the superior quality of welds it produces.

Buying a TIG welder can be daunting, especially with the many choices available. Based on my experiences, I’ve identified some critical areas: brand, duty cycle, amperage, portability, accessories, the type of metal you’ll be welding, and metal thickness.

One lesson that my years of TIG welding have taught me is that the brand of the welding machine significantly influences its performance and durability. Brands like Eastwood have earned their stripes for delivering reliable and robust machines, with countless positive reviews to back them up.

Duty Cycle

If you’re anything like me when I first encountered the term ‘duty cycle,’ you might be scratching your head. Simply put, the duty cycle is the percentage of a 10-minute period that the welder can operate without overheating. For instance, a machine with a 20% duty cycle at 200 amps can weld for 2 minutes before needing 8 minutes to cool down.


The amperage range of your machine is vital. When I started welding aluminum – a metal that requires more heat – I realized the importance of a machine with higher amperage. Conversely, lower amperage works well for thinner, more delicate materials.

Amperage RangeSuitable Metal Thickness
10-20 AmpsUp to 0.020 inch
20-50 Amps0.020 – 1/16 inch
50-100 Amps1/16 – 1/8 inch
100-200+ Amps1/8 inch and above


Portability is a game-changer. Having used both portable and stationary units, I can’t emphasize enough the convenience of a compact, lightweight machine – especially if you’re frequently on the move or have limited workshop space.


Right accessories can significantly enhance your welding experience. When I began TIG welding, I didn’t have a foot pedal, which made controlling the heat during welding quite challenging. So, make sure to get a machine with essential accessories like a foot pedal for heat control and a high-quality tungsten electrode.

Metal Type

The metal type you’ll be welding also plays a significant role in choosing the right machine. From my experiences, TIG welding works exceptionally well with stainless steel, aluminum, and other non-ferrous metals. However, keep in mind that some machines are better equipped to handle specific metals.

Metal Thickness

The thickness of the material you plan on welding is another vital factor to consider. During my initial days of welding thin materials, I realized the value of a TIG welder with lower amperage that could deliver precise and clean welds.

Wrapping Up

While our focus has primarily been on the technical aspects of buying a TIG welder, I can’t stress enough the importance of safety. Always ensure you have the proper safety gear, including a welding helmet, gloves, and a jacket.

There you have it – a detailed TIG welding buying guide, filled with real-life experiences, tips, and examples. I hope this guide assists you in finding the perfect TIG welder to fit your needs. Remember, the best TIG welder isn’t necessarily the most expensive or with the most features, but the one that suits your specific welding tasks.
