Induction Heaters
OK - so its a 40kW 60 Hz device. Induction heaters use the heating effect of eddy currents, and frequencies up to about 3kHz are used, Clearly a 60Hz version can use regular supplies from transformers possibly. If you have four coils, (which does not connect symmetrically to a 3-Phase supply)...- RFTrax

Induction Heaters
Induction heater coils are usually water pipes(for cooling) in an assembly that electrically isolates the quite pure water from a more general cooler via a heat exchanger. Provided you take it apart carefully, maintain the insulated places, you can re-make the shapes. Re-fill withde-ionised...- RFTrax

why battery charger voltages are high
Your charger is smart enough to be able to handle the (slightly different) charge needs for the two different types of battery, though I don't know if it is adaptable enough to figure out cell-pack voltages and combinations. Choosing NiCd as an example. The fast-charge type use "sintered plate"...- RFTrax
