Sirs: Purchased an I mig 200 about 1 1/2 years ago and have been very pleased with performance until recently. I was stich welding some sheet metal with flux core (all my welding is outside and breezy) and at about the 30th weld the arc quit. I power cycled, no help. Let rest over night still no arc. Wire feeds ok, green lit on, checked connections inside for tight or arcing. No evidence of arcing inside machine. Fuse ok. Voltage and wire speed windows lit up ok. Have been using 16 volts and 220 wire speed forever. Unit always welds as needed. Lite enough to carry around my truck yard for repairs. Is problem owner fixable? Could use asap.
