I added shielding gas

A project log for Hacking a cheap MIG welder

I'm modifying an Awelco MIG ONE welder.

One of the main drawbacks of this welder was the inability to use shielding gas, which ment it could only be used with flux core wire. I have added support for shielding gas. Welding with gas is much nicer than flux core, because the weld puddle can be seen clearly and there is almost no smoke. It also makes it possible to weld aluminum, but I'v not tried that yet.
