"So what if you cobbled up a 2N-whatever pass device in the line?"

I thought about that, and the first article I found on capacitive discharge welding was an article on welding tabs on batteries.  It included an SCR with a foot switch to discharge the cap onto the welding tip through the SCR.  I'm thinking I only have one chance at this and I do get good welds from single strands of #24 stranded wire onto a bolt with approaching the bolt with the wire, much like striking an arc weld, but not removing it since it's just a one hit type thing.  I'm sure any device in line with the wire/resonator would just pull energy from the weld to the switch and that's pretty much what I found by messing with it.

My biggest problem now is mechanical, how do I attach the wire to something that when it gets welded, I can un-attach the wire without disturbing anything.  Right now, I'm working on using some tweezers, but until I get some reproducible methods, I'm not going to try it.
