It's best to start with a HV climbing arc set up on the pig to dial in your
initial currents.  You can just use a few glass soda bottles as insulators.
Use a few surplus coathangers cut up for the arc rods.  Set the arc base at
1/4 inch spacing and the top at 5 inch spacing.  This will simulate a nice
load to check out your reactor current ratings at different settings.

Another great way to operate a pig is use a small reactance in series with
the primary and then wind approx 30 turns of #16 AWG insulated wire around
the center core section.  Hook this up to a 24 VDC power supply capable of
delivering around 10 Amperes.  As you adjust the current from the power
supply you will have a very effective way of continuously adjusting the pigs
current output while it is operating.  Be sure the supply delivers DC and
not AC currents.

Be very very cautious with a pole xmfr.  One mistake with these units
usually is fatal.  Have a flashing red light wired into the circuit
somewhere so you always know when the HV is "on".  A smaller flasher button
fits into the bottom of the lamp socket to make it flash.

Best regards,
