Sorry for posting that question... I was just cruising on a different thread and saw that you had already answered it.
Follow-up question: how is it self-tuning? Is it based on feedback from the coil? I'm assuming that it tries to insure
that you don't get current cancellation in the piece being heated...
Again, forgive my questions. I'm a theoretical genius in the use of induction fields in industrial metals processing
but this is the first time I've thought about the nuts-and-bolts aspects of how these go together.
