Please don't give me a bad rating for this. Its just a little extra info. you didn't mention that may help you find the problem. Depending on your specific model, there should be 1 or 2 breakers on the unit it self. If there is only 1, it will shut down the entire machine when tripped. If there are 2, the top one is for the whole unit and the lower one is for the wire feeder motor only. There is also a thermal overload that will shut down everything except the cooling fan. Secure the trigger closed and let the fan run for a while to see if it re-starts when cooled. If the depth of the weld was stable before the problem occurred, I would suspect a short in the motor and not the rectifier. That is not a sure bet though. If the transformer does not start when it cools, UNPLUG the welder and short the transformer to ground to be sure the capacitor is discharged. Then isolate the feed motor and transformer and use an OHM meter to test them individually to ground for a short. With a little luck, it will be the feed motor. Please let me know if this helped at all. I am new and still learning how to explain what I am thinking. Thanks for writing us.
