Hi

I wouldn't bother repairing it but I don't own it, and I was using it when
it broke down.

This mig has no model number on it but it was a pretty common one with a bad
reputation from what I have read. It has the the 4 position heat switch
labelled : 1 - 2 - OFF - 3 - 4 .

Any info, schematic or even just the wiring references would be greatly
appreciated.

Thank you
