In the middle of building a 60ftx4ft 100psf ramp at work and blew the breaker right at the perfect time lol so glad it blew at the end of the weld if it blew in the middle i would of had to cut the whole weld out and redo it. We run miller 354mpa with a xra feeder 047 5356 wire on 30amp 3phase circuits. Attached ImagesHigh Octane Welding
