sip 130 autoplus wire feed problem

[campervan72]

Hi i,ve an old sip autoplus 130 and has been a good welder to me but recently after 10mins or so welding the wire feed is very errattic sometimes stopping altogether .if i leave it for a hour and turn it back on it will work fine again for short period.

am i correct in thinking i,ve a problem on the wire controller pcb board with a component overheating ?

any ideas on how to find which component at fault or is it possible to get a complete board ?

any thoughts
Rob

I had the same from new with my Autoplus 130 many years ago and it was replaced under warranty. It was a transistor on the feed control board, that's all I can remember about it.
