The wire feed motor has started to run with a jerking pulsing,causing uneven wire feed.
With the motor disconnected and connected to a 12 volt battery it runs properly.
So I have proven the motor and gearbox to be good.
The motor appears to be switching off and on very fast, as if getting spikes from the ac power supply.
Anyone have any suggestions what to check on the PCB, before I replace the card, please ?
