The nine-part build history of a 10 kW induction heater is very enlightening, but a little bit of overkill for putting one's toe in the water. I've been eyeing: http://www.banggood.com/Low-ZVS-12-48V-20A-1000W-High-Frequency-Induction-Heating-Machine-Module-p-1038472.html I've bought other stuff from these guys, and it always arrives on time and works. The A$48 price is about US$36, so I'd perhaps buy two, even though postage is free, for when I blow the first one up through clumsiness. Point 4 on the page appears to make clear that the 12v must be turned on before the high voltage power; there are no interlock relays in this basic unit, and it's BYO fan, too. The supplied work coil appears to have an ID of 40mm, and height of 50 mm, but point 5 prohibits a work cylinder of more than 1/3 of the ID (i.e. 13.3 mm), to avoid overload and burnout. It could just about suit your application, Gene. They do talk about bigger heatsinks for more grunt, but then water cooling of the coil would be needed too, I guess. Is it worth taking a pocket unit to that level? Only if there's not enough round tuits for a bigger unit. My major problem is not having an actual use for the thing yet. I know I'd never get around to experimenting with a ground-up DIY build. Erik ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
