I have a 135, I built my rotisaree and my lifting frame with it and all kinds of other crap, I run a pretty small wire, a it's much easier to use on thin sheetmetal, when welding thickers stuff speed up the wire and slow down the torch, I'd not had any weld brake in my years of welding, and in my 48 foot long garage I don' need a 220v outlet evert 10 feet, thats the problem I'v having with my tig, I'm gonna just get a decent roll of 6/3 and put no-binds at both ends to it's not stuck at one end of the garage
