Let's be clear that this is not the earth wire - as in, the yellow/green AC mains ground cable. It is the work return cable, which has a clamp onto the workpiece. And that is in fact not a transformer, it is an inductor ( choke ). For some unknown reason someone has cut off the single heavy winding from the inductor, where it exits from the plastic bobbin, before it goes into the insulating sleeving of the splice. That splice joins the solid wire of the inductor to the flexible cable of the work return lead, just before it goes through a strain relief clamp on the front panel. Above the cut wire there is a small piece of sleeving protruding from the plastic bobbin of the inductor. It may be possible to unwind some of the solid wire and rejoin it. However, the welder may still not work, there may be some other reason why this wire was cut.I noticed that the earth wire isn’t connected to the transformer. It’s been snipped- you can tell from the wire.
Were you thinking the thin 'green / yellow', as opposed to the work return?
I don't know why the inductor output wire was cut. A mistake, a grudge, safety, vandalism, a very strong rat...I do worry that it's been cut to condemn it, perhaps for safety reasons. Therefore I'm a bit hesitant to connect it back up.
The first photo in post #29 is the inductor, but the second photo shows multiple thinner wires - the primary of the main transformer. Somebody really wanted to kill this welder.
Well Jack has a new welder, a working Clarke 110E.
And guess what I have?
As above, the primary's not repairable after the brutal attack. Maybe done in a fit of pique after the wire feed stopped mid-job, as the PBC has damage.
The ceramic 4R7 resistor is pushed against the gate SCR, which has partially melted.
Franken-mig time, I reckon.[/QUOTE
