How to Choose a MIG Welder

How to Choose a MIG Welder

Lincoln MIG welderAfter reading about the merits of the major welding brands and the general features to review when selecting a welder in this guide, you'll probably need to know a little more about the particular welder you want to buy. If you're looking into purchasing a MIG welder, there are certain features that are specific to a MIG welder for consideration.

Who Should Buy a MIG Welder?

Most welding operations have a MIG welder on hand for many of their projects, while many beginners find it easy to use right from the start. MIG welders have a wide range of applications. Here are some common uses for a MIG welder:

  • Hobby and Beginning Welders
  • Automotive Repair and Manufacturing
  • Welding Shops
  • Industrial Fabrication and Manufacturing
  • Anyone looking for a simple and effective way to join metal

MIG is not ideal for several applications:

  • Portable Welding Jobs (unless you have the right power supply set up)
  • Artwork 
  • Fine Welding Work 
  • Joining Thick Metals

What's Unique to a MIG Welder

ESAB MIG welderWires that are solid or flux-cored: MIG welders have a consumable electrode like stick welders, but there electrodes are metal wires. These wires may be solid metal and require a shielding gas. Others have a flux core that melts with the metal, rises to the top of the weld in order to provide a protective barrier, and is then chipped away when the weld is done. Some flux-cored wires use a shielding gas as well, which makes the flux easier to chip away.

Since MIG welders use relatively thin wires that are fed through the torch, MIG welders are naturally unable to weld thick metals that require a significant amount of filler metal.

Wire feed spool: The wires used for MIG welding are fed through the MIG torch through a wire feed spool on the side of the welding machine. The welder needs to only press the trigger on the torch in order to engage the wire, which automatically feeds itself into the weld pool. Having the correct wire speed for the job will make a significant difference in the quality of the final weld.

Features to Look for in a MIG Welder

A Spool Gun for Welding Aluminum: If you intend to weld aluminum, the one feature that most welders can't live without is a spool gun. Aluminum tends to get tangled when fed through the standard wire feed spool. The ideal solution is a spool gun that attaches to the torch handle and feeds the aluminum filler wire directly into the gun, traveling a few inches. If your welder doesn't come with a spool gun, make sure it at least has a mount where you can place it should you need one.

How Your Welder Handles Short-Circuiting: When a short-circuit occurs while welding, a surge of power may cause spatter and ruin the weld pool. Different welders have various ways to modify the electrical current when short-circuits are about to happen and prevent spatter and interference with the weld pool.

Thermal Overload Protection: Many top welders include thermal overload protection that will prevent your welder from overheating while you work. However, compare customer reviews to discover if your particular welder has had any glitches in the past, as a thermal overload is every bit as bad as it sounds. A thermal overload will turn your welder into an expensive end table.
