Sometimes we do Brazing Carbide Tips to cutter bodies and we do it with oxy/prophane. But quality is not good.
Does anybody know some Induction heater project aviable on internet?

That looks an impresive interesting project, From the experience I have had with Induction heaters is that if it is used in a production environment, it essential to cool the work coils by making them out of square copper tubing, with silver solder joints, also water cool the output switching devices by water cooled heatsink.

Yes that right! I can buy one commercial(used) here for $2500 and rated for 66kW. But that is like minivan :-) Actually I need only max 10kW to heat a tool.....
