I have done it many times both single strand and doubled up, carbon steel and stainless, works like a charm
Seems aluminum mig wire is the same as tig rod too. I now wonder about a cost comparison between using mig wire or tig rod. And then I would wonder if the aggravation of having to straighten and twist multiple strands even makes the ideal worth pursuing.
Technique that I was given by my welding mentor (Shield Arc) is amps equal thickness in thousands (ignore the decimal point) ( I hope I quoted it correctly)
1/8 = .125 = 125 amps
1/16 = .062 = 62 amps
etc
I do not have HF so I am scratch Tig only and thus can not drop off amps/pedal as the piece heats up as you travel along; especially as you approach an edge.
Some day I will have a "real" Tig unit but my current one does just fine. It is me that needs to improve.
