Welders are a key part of any automotive shop or business that involves welding. It’s also a handy tool to keep at home. MIG stands for “metal inert gas” and it’s preferred by people more than a TIG welder.

They are ideal for both at-home use and industrial use. MIG welding allows you to work at higher speeds and they’re generally very affordable.

MIG Welder Buyers Guide

So what exactly is it that makes a MIG welder a good one? Well, there are plenty of things to consider when trying to find your next machine for your shop or home. 

Who Are They For?

A MIG welder is ideal for those who are just starting to learn how to weld. They should be easy to use right out of the box. MIG welders have plenty of uses for them including: 

  • Welding shops
  • Fabrication & manufacturing
  • Hobbyists
  • Beginners
  • Automotive repair

MIG welders are not ideal for those looking to do artwork, find welding work, thick metalwork, or portable welding jobs. 

Spool Gun

If you are looking to weld aluminum, you’re going to need a spool gun. When you put aluminum in a wire feed spool, it tends to wad up and get tangled. A spool gun is a tool that attaches to the torch handle and sends the wire directly into the gun, only needing to travel a few inches rather than a few feet.

 If the welder you are eyeing doesn’t come with a spool gun, you should ensure that there is a mount where you can place it if you need one. 

Thermal Overload Protection

As you saw on the list above, there were a few MIG welders that came with thermal overload protection. This feature keeps your welder from overheating while you are working.

If anything inside the machine has been detected as overheating, it will automatically begin a cooling process and won’t turn back on until it goes down to normal temperature. If the welder doesn’t have this feature, a thermal overload will turn your welder into a stationary piece of furniture in your shop. 

Check Short-Circuiting Features

If you are welding and all of a sudden there is a short-circuit, the surge of power is going to cause splatter and will completely ruin your weld pool. You should look for a welder that comes equipped with a way to modify the electrical current when a short-circuit is about to happen. It will prevent splatter and any interference with the pool.
