I purchased the mig in non wroking condition. The torch trigger did not affects the relay. However when I jump the relay I have a/c and d/c output throughout the temp range with good voltages. The PCB was sent to the UK and rebuilt. He said that the relay should of still worked when the trigger was pulled. The PCB had an issue with motor power and he fixed it. He wants me to check the coil and the thermal regulator. He sent me the following diagram. Can someone LMK how todo what he suggests?
His recommendation:
Hi Chris
Attached is a wiring diagram for your machine. If you check that the thermal trip circuit is OK and the contactor coil is not open circuit.
