Subject: 10amp Hump
I got my new 5KVA pig from T&R this week. EXCELLENT SERVICE!
Ordered it on Friday got it on Wednesday. Boy is it big 250 lbs and almost
as tall as my wife.
Only having a 110v variac i am driving 1/2 the pigs primary. The welder is in
series, with a couple of 1500w heater elements across the welders primary.
What is interesting is that i see a 10amp hump in current as i bring the voltage
up before the gaps fire, no load. The hump is reduced by the heaters and
when the gaps fire the current goes up as expected but seems excessive for
the results produced by the TC. Any suggestions?
