"A 110-Volt, single phase machine (140+ Amp) with 75/25 mix of Argon/CO2 gas and 0.023" to 0.030" wire should do most of what you mentioned, welding 3/8" and thinner carbon steel."
Sorry, but you are not welding 3/8" with a 140 amp machine with any confidence, most everything else on this thread is pretty standard info.
my bad, should have been 3/16".
Any thoughts on the multi-process machines? I have not used one, I just thought $599 for that tewco was a good price? I don't see the TIG function on these as being very useful?
Dual-shield or inner-shield is a legit welding process. I think the wire is different than that used for flux core welding.
It welds really hot and you can put down alot of wire pretty fast.
