Operation Powering Up the Welder For most users, and 40Amp, 2 pole, 240V breaker will work for most applications. If you find that you are welding at the upper range of the rated output current or if you find that you are overloading (tripping) the breaker while welding, we suggest upsizing the breaker to a 50 Amp, 2 Pole, 240V breaker. Once the breaker size is confirmed, plug the welder into the appropriate matching receptacle and turn the rotary power switch to the on position.
