I have a Powercraft No gas turbofan cooled welder 25-130 amp. I have no wire feed. The machine stopped in the middle of welding. I can just about read a meter so I am having difficulties. I can hear the relay click when I press the trigger. I have voltage on the diode. In desperation, I have changed the relay, the diode, and the thyristor. The fuses are ok and I disconnected the motor and it tests ok. I can't see any breaks in the board. Can anyone suggest what I can do to get this thing working?
