Light bulbs are low cost high wattage and low resistance resistors. I looked
at it quickly and it seems the light bulb was serving as a current limit
resistor for when the electrode shorts out.

In the latest issue of one of the home shop Machine mags, they had a
feature with a home built EDM which for some reason used light bulbs
(controlling the freq. I guess)
anyone have more detailed plans for the electrical side of this
project or point me in the right direction?
I have a few broken exhaust studs that I'd like to remove myself
Thanks,
Mike
