Very ggod device. The secret is that you need a big power supply. First I used a homemade ps from two transformers from microwave oven 40 v 25 A. Later I used a ps from a transformer 25 v and many many Amps from a cinema machine of 1970 s . I managed to get red a piece of iron of a 25 mm diameter in 90 sec. A good current is 20-32 V 15 A .Don' t use more than 20 A for alot of time to not burn the mosfets. The induction begins after 12 v.I used a fan from a microwave oven to keep the heatsink of the mosfet cool. In the big ps i used a 35 A bridgfe rectifier with big heatsink and afan from computer (12 v).Don' put items with diameter more than 3 cm and more tha 4-5 cm long to keep the amps less than 20.If you use a voltage regulator with triac on the primary of the transformer the voltage must be more than 150 v to not burn the bridge.It's better to use a variac to have always a full sine wave in every voltage you need.
