I tried all these ways mention on cutting cable, every way leaves a frayed end, and tape dont hold up, torch is ok-ish. Mig welder is the best, clamp the cable in the vise<snug, with some good cable showing, ground clamp on, .030 wire in the mig welder, heat on high-ish, cut/weld the bad cable off, quickly-ish> take the cable out of vise, take Ford wrench and peen over the red hot end of cable on the anvil part of the vise, now you have a very nice sealed cable end in a matter of minutes, your welcome. A stick welder will also work with 3/32 6011.
For those of you that have a cable cutter in the woods with you or at the shop, I strongly recommend safety glasses, I seen someone cut cable with no PPE, that was a bad day for him.
