Ok I went to weld up my custom trailer hitch today and much to my surprise my Millermatic 175 MIG unit wouldn't operate..How can this be? it has less than 10 hours of use on it. ???
It has power, the fan turns, when I close the trigger argon flows out the torch. What I dont have is any wire feed or and Voltge at the torch, i.e. it wont even make and arc of any size, even with both knobs on MAX

I took the cover off and the thermal circuit breaker has voltage on both sides. I verified 230V is geting to the circuit board.. The board had a green LED that glows and a red one that blinks "on" when I squeeze the trigger..

Any IDEAS.. I'm calling th repair shop tomorrow?
