I bought a Hobart Handler 140 a while back and just recently noticed that the owner's manual mentions settings for welding aluminum. My impression was that to MIG weld aluminum I needed a spool gun but Hobart doesn't sell one compatible with the 140. Can I simply change out the spool for aluminum and run with pure argon or are there other parts ...

For most jobs welding stainless steel, you'll want to use .030-inch diameter stainless steel welding wire. For thicker base pieces, step up to .035-inch to .045-inch welding wire. For MIG welding stainless steel, a shielding gas mixture that's 90 percent helium, 7.5 percent argon and 2.5 percent carbon dioxide is generally ideal.

The settings for Flux-Core wire and non-ferrous metals will be completely different. Metal Thickness & Amperage Settings: When welding mild steel, a good rule of thumb is to set the amperage level at 1 amp for every 0.001" of thickness. So if you are welding 12 gauge mild steel with a thickness of 0.100", you would set the machine at 100 amps.

MIG welders are different to ARC welders in the biggest sense because they use a fed wire instead of rods. The wire (steel) is fed from the roller or feeder through a torch and then protruded from a tip. Because most wires are just metal, the weld must still be protected to an inert gas is also fed throughout the torch to shield the weld from oxygen and moisture.
