Basically, from a 120V receptacle, you can weld 16-gauge steel sheets together with a single pass. This, by 120V MIG welder standards, isn’t all that powerful, but for most household repair jobs, this should suffice.

The 140A has two knobs that control voltage output and wire speed. Without synergic adjustability, users are free to select the pace and welding heat necessary for light-duty welding jobs.

If the need arises, you can take this machine to weld aluminum sheets together (spool gun not included).

This MIG welder is equipped with inverter technology to regulate voltage conversion. Essentially, this lets you take the 140A out into the wilderness and weld by plugging it into a portable generator.

Pros

  • Extremely portable
  • Excellent duty cycle efficiency
  • Works on aluminum
  • Easy-to-setup controls

Cons

  • Could weld thicker materials

All in all, the SUNGOLDPOWER 140A is our top pick for its versatility, portability, and user-friendliness. There are more powerful models out there, which you’ll see in a second, but the 140A deserves more recognition than it gets.

With more homeowners trying their hands in DIY home repair tasks, we’ve seen an influx of home-grade tools at the ready.

FAQs

Here, we’ll address some of the most frequently asked questions about 120V MIG welders.

What’s the difference between 110V, 115V, and 120V?

One of the most confusing things buyers will face is choosing between 110V, 115V, and 120V appliances. Despite their technically different input ratings, they’re the exact same thing. We won’t get too technical about their differences, but in a nutshell, the difference in voltage between the three is minute, and plugging a 120V welder into a 110V receptacle will not result in a significant loss of power.

Which MIG welder brand should I choose?

That’s entirely up to you. Back in the day, the dominating forces in the welding industry were Hobart, Everlast, Lincoln, Miller, and Forney, but today, you’ll find MIG welders from unknown companies with similar performances as name-brand models. The benefit of going with a widely-used manufacturer is their after-sales service; many Chinese-made MIG welders don’t offer such services, so finding replacement parts is close to impossible.

Do dual-voltage MIG welders automatically detect input voltage?

We can’t speak for every model on the market, but the two dual-voltage MIG welders listed above—the SUNGOLDPOWER 140A and Weldpro 155—have auto-sensing features to adjust its max power output based on its voltage input. However, accidentally plugging it into the “wrong” receptacle is impossible since they use different types of plugs. The 220V plug adapters come with both of these models.

Where can I use a 120V MIG welder?

Anywhere where a 120V receptacle is available or, if you need to weld in the open air, wherever a portable generator is accessible. 120V MIG welders are mainly used for light-duty welding jobs, and thus, may not be up to the challenge of most commercial-grade jobs. However, it depends on how thick the material you’re working with. Even auto parts fabricators can make use of a 120V MIG welder to recreate or patch up corroded parts.

Summary

In order to create this guide on the best 120V MIG welder, we personally tested over 40 different MIG welders from various brands and countries to see which of them are top-performers.

Based on our test results, we’re confident you’ll find value in each and every model we listed above. Our comments section is open to feedback, questions, and anything else on your mind.
