I have a chicago electric inverter 80 amp arc welder, and everytime i run about 3/4's of a rod it pops the breaker. It says its 120vac/60hz/20amp, and my breaker is supposed to be 120v 20amp, so why is it popping? I am thinking the amps, but i dont know much about the subject. If its the amps, is it possible to get some kind of adapter to let me use the dry outlet which is 220v/30amp? Trying to find the cheapest method.
