I bought a new miller welder and the Mig Gun Nozzle grounds out and arcs when it touches the work piece. I'm running solid wire with shielding gas and the polarity is set up correctly. Almost seems like an insulator is failing.
This happened before I had any slag build up, brand new nozzle.
If the nozzle is arcing it means the insulator between the nozzle and gas diffuser is probably shot. You will have to either replace the insulator or make sure you don't touch the work piece.
Arcing outside the weld zone is not good, can lead to inbrittlement and cracking.
Oh, and good job on buying a miller...i hate it when people buy crap gear and expect miracles(or ask me to perform them with their junk welder)
