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. :(
