I've got a little 120V flux core mig, it does great on little jobs but puts out a lot of splatter.

I am torn on my choice for my next welder: a tig or a 220V gas mig... Probably will go for the Tig... They just make such nice, clean welds. They do put more heat down, but the heat is very concentrated, and you can control warpage easier... seems to me anyway.
