Hi there,
I own a simple chinese 150 MIG machine, wich worked great after today.
When i put the power on and trigger the switch on the torch, i hear a relay clicking and thats all.
When i measure between Ground and contact tip i measure 18v dc, when i press the wire button the voltage drops to 0v
What can it be?
I found a picture of the same pcb in another topic, it is this one
