Sweet! I guess that's the dual power one then. Never used a spoolgun. I had a suitcase for a while, absolutely bitchin but kinda overkill for anything I could weld, unless I decided to build a bridge on the property! Can't remeber exactly which model mine was now, but had to run it off a big welder like a bobcat or trailblazer.
edit: I remember, it's a miller s32p
