Hi Jon - I've an old commercial Watton Electronics "Arc-out" tap
buster that uses a vibrator coil (solenoid) to peck the electrode up and
down. It only outputs 12-15V DC and runs fine using plain old tap water,
as per the manual.

It more than paid for itself on the first commercial job removing a
broken stud out of a cylinder block for a local garage. Beauty of it is,
it's portable and can be set up almost anywhere. It's done quite a bit
of work once word got around <G>.
