Hi All.
I have joined this forum as I am doing more welding than I used to and have just got an old Norman Butters NBC200P to provide more grunt than my little Cebora. The NB welder has problems. The earth wire where it comes into the main unit was fried as was the earth wire inside the wire feed unit. The +ve welding cable was loose on the torch connection fitting on the wire feed unit and looks like it has slipped round and arced onto the frame of the wfu. I think the welding current has found its way through the machine supply earth to get back to the work piece or bench -ve. This has fried a few other wires too.
It all looks pretty simple but wondering if anyone has a wiring diagram and a user manual?
Cheers. Rob
