Or, could tell me if, and by ho wmuch, a variac can safely be overdriven?
I think you can overdrive them up to twice the rated current if you only do
short runs with breaks to let it cool down.
I have jsut a 4.5amp
If you overdrove it to 8A at 120v that's 960w which is about 52 spark
inches. enough?
