New to the forum - hello all. Can anybody give me a 'heads up' on a problem with my welder please?
Its a 1985 SIP Autoplus 120 - bought new by myself direct from SIP. Has been an excellent welder used
mainly for car restoration work but has also done a reasonable amount of fabrication work too.
Is the earlier '2 dial' model with infinitely variable power control and wire speed.
Problem I have is tempramental wire feed - sometimes it does, sometimes it doesn't. [ Gas supply always
works]. Have diagnosed problem to pcb area - using multimenter no voltage at the block connector that
joins pcb output to motor wire input. Nb the main relay is working correctly with both circuits visually operating.
Problem has started after i rolled welder a decent distance outside over monoblock [ so slightly uneven] so
consider this may br root cause.
With reference to my pictures, only obvious issue i can see is the small black plastic bracket on bottom left corner
of pcb - it looks like something used to be there but now isnt? [ However welder is currently working so
this is not source of my problem]
Any help appreciated
