I don't get that much welding cable but i usually cut it into 12-18 inch lengths and run it through my electric stripping machine. The main problem is that the wire inside is a finely stranded wire and crushes easily. You have to set the cutter to a depth where it scores the insulation but doesn't really cut too deep. I pass it through a few times and that weakens the insulation enough that it peels off okay.

You've got the cutting wheel set a little too deep if the cable skitters off to the sides when you're passing it through. ( It's a fussy adjustment to get it just right.)

Jumper cables are kind of a booger to do because the insulation is so thick.

This is one of those tasks where a chopper / granulator would be the better tool for the job. You might just sell the welding cable at the yard as high grade insulated copper wire and save yourself all of the work. Figure one way ... you get ICW price. Stripping it probably wouldn't give you better than #2 copper price. There might not be a huge difference between the two where you are.



You just have to figure out whether or not the juice is worth the squeeze.
