I had a 3ph welder (that didn't work). It seems they use a very small DC current (2 amp fuse) in a 3rd winding to control 500 amps of AC. The circuit board that controlled the DC was bad.
So are the 20ga wires from a circuit board? Though I would try to find more info, parts are very expensive, or maybe out of production?
