The most beginner-friendly welding process out there — continuous wire feed, shielding gas, and a forgiving arc. Here's what to run it with.
MIG Welding Buying Guide
MIG (GMAW) is where most welders start and where a lot of them stay. The continuous wire feed and shielding gas make for a smooth, forgiving arc that's easier to learn than TIG or stick, and it's fast enough for real fabrication work once you've got the hang of it. Good for auto body, general shop fabrication, and anything where speed matters as much as precision.
Curated Picks
120V wire-feed workhorse and the go-to first MIG for home shops and light auto-body work.
Dual-voltage (120V/240V) flexibility for stepping up to thicker material without outgrowing the machine.
Professional-grade auto-set MIG with spool-gun compatibility for aluminum work.

Common Questions
MIG uses shielding gas for clean, low-spatter welds indoors. Flux-core skips the gas bottle and uses a flux-filled wire instead, which holds up better outdoors or in a breeze but runs messier and spatters more.
120V machines comfortably handle up to about 1/4" mild steel for hobby work. A dual-voltage 240V-capable unit gives you headroom for thicker material later — worth it if your garage already has the circuit.
Only with a spool gun or push-pull gun, aluminum-rated wire, and 100% argon shielding gas. A standard steel MIG setup won't do it well.

The precision process — tungsten electrode, separate filler rod, foot-pedal control. Slowest to learn, cleanest results.
No gas bottle, no wire feed — just an electrode holder and a rod. The most portable, most weather-tolerant process there is.
An ionized gas jet that slices through any conductive metal — faster and cleaner than a grinder or torch.
The arc, spatter, and fumes don't discriminate by process. The right gear is what lets you weld for years instead of visiting urgent care.
