Are 120V Welders Worth Buying?

Factors to be Considered while Buying the Best 120V TIG Welders

While buying a 120V TIG welder, you must keep the following factors in place to avoid any inconvenience after buying one for your welding needs.

What Voltage does the 120V Welder Offer?

It determines what types of material you are going to weld & the quality of weld joints.

Arc requires a reasonable amount of power to initiate. If you intend to melt thick & strong materials, you will need one that runs on a higher power.

On the other hand, if you want to perform a simple domestic welding operation that doesn’t require higher power, the one with a smaller voltage will do the job.

If you intend to work on a commercial project requiring higher power, you will need one that provides higher power.

Need to Be Carry or Not?

If you want to use a welder in domestic operations like in the garage that does not need to be carried around, you can go with the heavier one. On the other hand, if your welding projects are outdoor, then try to buy one lightweight, which is easier to move around.

Here, you are supposed to choose between higher power output and portability. The more portable, the less the output power and vice versa.

What Duty Cycle is Required?

Opt for one with higher duty cycles if you want to perform welding operations requiring long work hours. On the other hand, a smaller time welding operation can be done with one’s offering less duty cycle.

A smaller can do the job well if you give them time to cool down during the welding operation.30 per cent duty cycle welder is the one we recommend.

What Wire-Feed Speed does it come with?

The welder that allows changing wire-feed speed or the one that runs on a low wire feed is the best option for beginners. You need to be an experienced welder to work with fast wire-feed speed, which requires quick action. So, if you are a beginner, you won’t be able to achieve accuracy if you are using one with a fast wire-feed speed.

Safety Features?

The low-quality machines sometimes produce unstable arcs, resulting in spatter on metal. So, if you want to have cleaner welds, you shouldn’t opt for those with low prices.

Working with electricity and metals is sometimes dangerous. So, go with one that automatically cuts off when it begins to overheat.

Additionally, you should always wear protective welding gear like gloves, lenses or helmets.

Worth Reading:


Can we use a 120V welder for TIG weld?

You won’t be able to get proper results while tig welding with a 120V welder until you use a 20 or 25-amp breaker with it. Regular 15amp 120-volt won’t work with these small welders.

What thickness a 120v Tig Welder can weld?

It welds mild steel ranging from 24 gauge to 3/16 inch thick(0.8-4.8) in a single pass and other materials thickness ranging from 24 gauge to 3/8 inch in a single pass. By using an MVP(Multivoltage plug), you can use both 120/240V input power.

Summing it Up

If you have read this far, you just learned about the best 120 V TIG welders on the market, and these are the tig welders we tested in different welding scenarios.

The best one in our list that we found to be suited to most welding tasks and also not heavy on the wallet with lots of functions is PowerArc 140STi.A dual voltage 120/140 welder offering high power output weighs only 20lbs.

Our second most preferred 120 tig welder is AplhaTIG 203XI. Though it’s a bit expensive to buy specifically for welding tasks that require 120V, the functionality it’s equipped with is worth it.

However, if you want to buy something that comes from reputable sources, then Lincoln Electric LE31MP is your best bet, but other welders on the list offer similar functions at half the price.

Now, the chance for you to be an owner of a welder that suits your needs is in your hands, just like the welder will be. Happy Welding!
