I called called to do a stainless tig job at a plant and all they had to power up my welder was a 11,000 watt Bobcat generator which probably means 9,500 or maybe 10,000 watts of power.
It would turn the machine on but as soon as I tried to weld tig stainless at 125 amps it shut right down.

They then decided to let me pull my truck inside where I was able to run the Dynasty 300 DX off my Pipe Pro which puts out 12,000 watts of power.

Earlier in the day I was welding up aluminum hand rail with my set up and it allowed me to run at 175 amps on AC.
