The best flux core welders have sufficient amperage range to handle any job you will tackle, a high enough duty cycle that you don’t lose too much time, intuitive controls, and are dual voltage.

The Hobart Handler 140 is my top choice because it is both powerful and versatile for a wide range of tasks. It features simple controls and durable construction with a smooth arc. It is ideal for beginner welders looking for an affordable and reliable flux core welding machine.

Flux core welding machines are ideal for beginners because you don’t need to think about gas or leasing bottles. You can buy a pack of flux core wires and get started. They are generally cheaper than traditional MIG welders and are more portable.

Selecting from the hundreds of models of flux core welding machines can be difficult, so I have narrowed down your list to the top performers based on my personal experience. Some welding machines I own, some I have borrowed, and some I have used in friend’s workshops.

Things I Don’t Like

I find the duty cycle to be a bit limited for my needs. It’s unsuitable for heavy-duty welding tasks, and I need to be careful not to exceed the duty cycle. Additionally, I have to change the wire spool frequently, which can be a bit of a hassle.

I also don’t like the amperage control knob – rather than showing you the exact amperage you are selecting, it gives you a 1 to 10 scale. For someone who wants to dial in an exact power, this is frustrating.

Lincoln Handy Core Welding Machine

Verdict

The Lincoln Electric K2185-1 Handy MIG Welder is an excellent choice for hobbyists and DIY enthusiasts needing a portable, easy-to-use welding machine. It’s ideal for small welding projects, such as automotive repairs, and produces high-quality welds.

However, it’s unsuitable for heavy-duty welding tasks, and the limited duty cycle may be a deal-breaker for some experienced welders. You will likely outgrow its limited power very quickly and need to upgrade unless your jobs will remain small scale.

Flux Core Welder Buying Guide

Welding machines are complex and require in-depth knowledge before making a selection. But there are a few key specifications you can narrow your search down to make your shortlist easier to review.

When buying a new welder, I have a concrete view of the max amps, input voltage, duty cycle, and wire size based on the work I intend to do with it.

Amperage Range

When choosing a flux core welder, you will notice that the more powerful the welding machine is, the more it costs. Therefore, you should pick a model that has sufficient power and no more.

The max amps are one of the most important considerations and will dictate the thickness of steel you can weld. This table will give you a rough idea of how much amperage you need based on your thickest jobs:

Amperage RangeThickness of Mild Steel
30 – 90 AmpsUp to 1/8 inch
70 – 140 AmpsUp to 1/4 inch
125 – 200 AmpsUp to 1/2 inch
300+ AmpsOver 3/4 inch

The amperage range also affects the quality of the weld. If the amperage is too low, the weld may be weak and ineffective, while if the amperage is too high, the weld may be overheated and prone to defects.

You may also want to review the minimum amperage – if you intend on welding very thin material, reducing your amperage is also important.

Input Voltage

Flux core welding machines can have different input voltages, affecting their suitability for various applications. The most common input voltages for flux core welders are:

  • 120V – Flux core welders with a 120V input voltage are suitable for light-duty welding applications, such as household repairs, DIY projects, and small-scale welding projects. They are also ideal for use in areas with limited power supply.
  • 240V – Flux core welders with a 240V input voltage are suitable for heavy-duty welding applications, such as industrial welding, construction, and fabrication. They are more powerful than 120V welders and can handle thicker materials and longer welding runs.
  • Dual voltage – Some flux core welding machines have dual voltage capability, which means they can operate on both 120V and 240V power sources. Dual voltage welders are versatile and can be used in various applications, from light to heavy-duty welding.

It’s essential to choose a flux core welding machine with the appropriate input voltage for the type of welding you will be doing. If you are working on small-scale projects or DIY repairs, a 120V welder may be sufficient. However, if you will be welding thicker materials or working on industrial projects, a 240V or dual-voltage machine may be more appropriate.

PRO TIP: Don't buy a flux core welding machine that requires 240V if you don't have access to it in your workshop.

Wire Size

The most common flux core wire sizes for welding are 0.030 inch and 0.035 inch. However, other sizes are also available, including 0.025 inch and 0.045 inch.

The wire size of your flux core welder is an important consideration because it can affect the quality of the weld, the appearance of the finished product, and the overall welding experience.

When selecting a wire size for your flux core welder, consider the material being welded, the amperage range of your welder, and the specific requirements of your welding project.

Duty Cycle

Duty cycle indicates the amount of time a welder can operate without overheating. It is expressed as a percentage and refers to how long a welder can operate at a particular amperage before requiring a rest period.

For example, if a welder has a duty cycle of 60% at 200 amps, the welder can operate for 6 minutes out of a 10-minute cycle at 200 amps before requiring a rest period of 4 minutes to cool down.

A suitable duty cycle for a flux core welder depends on the specific welding application. Higher duty cycles are generally better for heavier-duty welding applications that require longer welding runs, while lower duty cycles may be sufficient for lighter-duty welding projects.

A typical duty cycle for a flux core welder is around 20% at maximum output. An important mistake to avoid is a low duty cycle at less than maximum amperage. For example, a 20% duty cycle at 90A on a 140A welding machine is a genuine concern, because the duty cycle at maximum amperage will be incredibly short.

Portability

Flux core welders are much more portable than MIG welding machines because you don’t need to transport a gas bottle. But, you shouldn’t ignore the weight and dimensions of your potential machine.

You may need to move your welder around your workshop or load it into your truck for dozens of reasons. Having a machine you can lift easily and transport with one person makes it significantly more useful.

It becomes a real pain when you need to upgrade to having a powerful welding machine in your workshop and a secondary smaller welder in your truck. The ability to do both with one machine is a real money saver.

Having said that, I also wouldn’t sacrifice power to save weight. Some of the smallest flux core welding machines have under 100 amps of power, which isn’t enough amperage for tasks I will likely encounter.

Conclusion

So many models are available on the market that it can be difficult to select the best flux core welder. Step one is to understand what you will be welding and how much amperage that requires. After this you can choose the best duty cycle, wire feed rate, and input voltage.

My recommendation is the Hobart Handler 140 MIG Welder. This is suitable for both beginners and experienced welders and is versatile enough and powerful enough to handle 90% of DIY welding jobs.
