Hey to everybody!!
 
I've heard that a variac can be used to regulate amperage as well as voltage.
Can anybody explain to me how this is done?
I just purchased a model 1256 from Dave Wightman for $50.00 and am considering
another for 
amperage control on a large coil that I'll build someday.  The variac steps up
120v to 280v w/o load, and 240v to 500v w/o load.
I just got 78mA out of a 30mA NST for a very short time (didn't want to burn it
up)
With load the high end drops slightly.  The variacs are rated for 28 amps and
weigh about 80+pounds.
 
Thanks in advance,
 
Trent Mullins
