Im a newbe to this newsgroup, and have been wondering if it would be practical to use a DC stick welder as the power supply for a tig welder. I have a regulator, (from an old cheap, and dead, mig welder), and a Power-Mate AC/DC welder that goes from 20 to 140 amps on DC. Could I just get a tig torch, ($30 from Harbor Freight), and use the stick welder as the power supply? I realise that I would have no pulse, stitch, or HF start capability, but neither do any of the less than $1200 dollar tig units. If this set-up would be practical could it be used effectively on 16 gage sheet steel?
