Once it was stated what it was the thrill was gone. :-)
My Dad has a Cyber Tig. Its a heavy machine. We had to adjust the
spark gap many years ago, but those electrodes are pretty beefy and last

It looks like some kind of RF noise generator. Actually the file path
name with "TIG" in it gives it away.

generated the hi-freq that makes non-contact arc start possible. If you
remember the earliest transmitters were a spark gap ... eg. wide-band
