Inductive heater

[Vinny]

I also bought one a few years ago from China. Yes, the pump pumps water thru the coil. For a power supply I bought a 20A supply from some other Chinese vendor really cheap. I *still* haven't tried it out. Heat treating is exactly what I bought it for. Somewhere, probably here, I read about a company using an electromagnet to hold parts in the air as they passed thru the induction heater. When they were hot enough they were no longer held by the magnet and dropped into the oil bath below. I was thinking something similar on a much smaller scale.
