RE: welder power source

Original poster: "Owen Lawrence" <owen@xxxxxxxxxxxxx>

I thought Tesla coils got their high voltage from resonance, not number of
turns of wire in the coil.  The large number of turns in the secondary
balances out the tank with the small secondary capacitance (the toroid) so
its resonant frequency matches the high capacitance small inductance primary
tank circuit.  At every ring cycle you're adding a little more "pressure"
(i.e. voltage) in the secondary circuit until it overflows into a spark.

	Naive, but am I totally out to lunch?  I have often thought it would be
really neat to make a coil that sparks without any high voltage primary
boost to get it going.  Everything would have to be made really efficient
because the trip from low voltage input to high voltage output would be a
long one.

Bobby:    The output of a stick welder is only about 30 vo;ts. If you have a
secondary of 1500 turns with every thing ideal, which it is not, you could
not expect over 500 volts out. That would not be enough to make any visable
spark. Even a kicker coil tesla uses 115 volts to power the primary. 30
volts would not be a good source of power. Ignition coils are not an ideal
source, but they put out 36.000 volts which is much better than 30 volts.
      I think you should look for a better power source.
