The highest amp draw is typically through stick, you can do it on wire I suppose but it might as well be a stick at that point, 400A through a wire would be a neat arc, not to mention hot. I know I ran some bigger millers with shielded metal and gas, with wire that was close to 1/8, those were cool, well not quite.
Most new machines will run both, if not all three ways, tig, mig, stick. Miller has had big clunker switch on the front of there bigger units for a years to switch between cc and cv, now its a little switch.
At first I thought he was talking about a motor-gen set, never really thought about a regular 3 phase transformer, he must have a decent service to be thinking about that. I cannot even run a little buzz box without making my lights go dim at home.
