Daniel: Every time someone sets up a DC coil I advise a serge coil to
prevent power arc Some people say My coil can,t work it is to small. I don't
tell the coil that and it gets the job done. I use 15T of #12 house wire 1"
dia air core coil streched out 6" long to stop turn to turn arc when it
fires. I place the surge coil next to the spark gap so no capacitance will
kill the small inductance. My main cap curent ie over 400 amps but this coil
disconects my power supply when it fires without a time delay before the
next cycle.     Robert  H
