    Sounds like the wire feed control pcb is not pulling in the main contactor relay. is it a seperate wire feed unit with an interconnecting cable to the rectifier?

Phase three on cv or cc have current going to mig wire, wire is live without hitten gun trigger. mega arc is hooked up to a Hobart suitcase


May need to take gun apart and see if trigger is sticking or replace lead.

we use Miller at work. The feeder has a switch that makes the trigger turn off and on with quick pull of trigger so you don't have to hold it entire time.

check wiring to make sure it's wired right so your not bypassing the trigger switch.

hope it helps.

MY CLARKE WELD 235 TEN TURBO ARC WELDER HAS SUDENLY STARTED BLOWING FUSES WHEN IT ARCS UP ANY IDEA


More then likely you have a shorted component (positive or hot wire to ground). Verify that the gun/trigger assembly is in good shape and has no broken wires that are touching the ground or case (may have to disassemble). Thats the easiest thing to check, everything else is inside the unit and will take more sophisticated knowledge and equipment to diagnose.

Mig welder started to arc out on its own. You dont touch the trigger and when you put the wire to the grounded table it blinds the **** out of you. Could use some tips on repair. Thanx. Shane.


Try replacing the feed tip as this is an insulator that keeps the wire from touching the tip as it feeds out. These tips need replacing often as they also provide a friction free surface for the feed wire.

I have a craftman mig 110v mig welder arc problem


Check to make sure the contact is not touching the nozzle of the mig welder. This would definitely short it out!
