Re: Tesla coil help

The old 225 amp stick welders make good ballast for pole pigs.
To use a welder as an input ballast for a pole pig, you simply
hook the 240 volt input of the welder in series with the 2 outer
low voltage secondary bushings of the pole transformer. Leave
the center low voltage bushing of the transformer unconnected.
Also, short the output welding leads of the welder. You can use
the welding current selector of the welder to give some degree
of control over the input current to the pig and by shorting
the welding electrode leads, you can draw up to 50 to 60 amps
at 240 volts with the pole transformer, therefore yielding 14.4
kV at around 700 mA, assuming that you have a 14.4 kV pig.
