This is bottom of the line EDM, I assure you. Because there is no pulse
controller, the sparking is at a low frequency controlled by the RC time
constant of the components used. I have used this to burn out taps, and
it works pretty well for that. It is not going to burn holes in 1" of steel

in a few hours, though. But, if you want to experiment with EDM, this does
actually work.
