Hi guys
Just a follow up on this welder.so it turned out to be a small circuit board that controls the wire feed motor.
The guy that repairs them use to send them away to have them repaired ,but that person has since retired.
So i had to get a new one !!$270 later it works fine.
Its a shame these people retire ,and seemingly don't pass there skills on to the younger ones,seems to happen in a lot of industries these days.
Its turf it buy a new one.
cheers rob
