big control unit
A friend of mine found this big three phase welder at a machinery auction, he bought it and then resold it to me for the $100 he owed me. I think I came out very well on this deal!
As shown, It has a very large three phase variac rated for 200+ amp per leg and also has a very nice variable inductor at 200 amp per leg.
This unit will become my main power control unit for the 13khz coil and all future systems. I will set it up so that i can control voltage, current, AC, DC, one, two, or three pole pigs at a time and anything else that i can think of? The front mounted crank adjustments for the variac and a crank for the current inductor will be vary handy, plenty of face plate room for bells-n-whistles, "E"-stop and key switches.
I love it, can't wait for spring so i can finish building my new lab, I'm planning on building a 30' x 30' x 16' pole building atatched to my old grainery that will give warm and dry firing space for coils. The grainery will be the new lab (time to move the hv lab out of the house).
