[Ben tyson]

Hi , I'm new to the forum
Basically my issue is that my wire feed dial has stopped working but when the trigger is pulled it's at full feed speed . I am unable to adjust the wire speed via the dial ?
Had anyone had this issue
That may be able to help me please
Cheers
Ben

Welcome Ben. It is usually down to a shorted transistor on the pcb causing full voltage to be fed to the wire feed motor. Look at the transistor mounted to the heatsink on the pcb. It will be that one usually. It has cropped up in the SIP section before.
