Neat! Would this be a modern turret control, or one from the 60s??

You mean impedance match as the arc forms? That sounds, well, quite
challenging! :)

After reading more this book indicates that while you probably could use
regular xfrm material - the response would suffer and the energy loss in
the core would be rather large.
So I probably wont' try it. :(
