Cool.

Maybe you could also use it to make an 'ultimate EOL lamp fryer'

I need one of these. Instead of frying lamps they'd probably just go boom

Without ballasting on the primary, this will be able to dead short your supply when you short the secondary. Actually, without ballasting it will most likely trip your breakers just with its magnetization inrush alone

So you must ballast it. And when you do, the secondary current is limited according to the turns ratio. With a 30A heating element array as ballast on the primary, secondary will be limited to 1A..

You are going to use it to arc across the 7200V output. Without ballasting this is equivalent to a dead short
