Sounds like a candidate for a HSM project. I wonder how much current

Before I snagged a German blade welder on eBay, I had built a very bad
homebrew one. I found a transformer that had a lot of available "window"
still open, and wound a couple turns of battery cable through that, and made
up a clamp for the blade. It worked remarkably well for a total jury-rig
setup. I know if I had kept on working on it, it could have made decent
blade welds. The transformer in a Do-All welder is remarkably small, but
obviously purpose-built for the job.

Any chance you could slip a clamp-on ammeter on that puppy while
welding, and also voltage?
