One trip the hardware store later and I’m ready to hook utilities up to the induction heater.
Hooking up cooling water isn’t the only step… Power!
I also ordered a larger variac, a 5000VA 220V model to aid in testing and firmware optimization. I have a small 2000VA 120V variac but running it on such low voltage skewed a lot of the readings. The variac is nice because running full power while testing new features can a bit nerve-racking and wasteful.
