Induction Heater Melting Stuff

Due to scepticism about my home made induction heater by some people. I thought I would add another video. This updated power supply uses a normal half bridge igbt inverter with a conventional induction heating setup. The heater melts a 50p coin and a crome vanadium steel allen-key socket. For those interested...The frequency lock is achieved using work coil current feedback to a free running oscillator which drived the two hgtg20n60a4d igbts through an ir2184 drive chip. The secret to melting steel at low power is to use less turns on the work coil. Molten steel has a much higher resistance than cold steel and requires less turns to couple energy to efficiently. The current used here was 13 amps at 240v (3.1kw). Peak igbt current was 50 amps at 120 khz. The capacitors are the only critical component- i used celem csp150/200 's 2 x 1.6uf

I am studying a project a centrifuge inductively, which I will use the induction eletromagnética for the fusion of metal.... You could help me on induction Heating Schematic eletric?

See Richie Burnett's site, he has a lot of useful info for you.

[marieomagpie]

it looks like you built this your self, do you have plans, i am interested

Very very nice! Did you use an LCLR circuit or a current transformer to bring the power into the tank circuit?

What's your effective work coil voltage when steel has room temperature and when it's near melting?

I am new to induction heating but would like to build one just like yours.

Where do I get the schematic diagram from to build one?

Operating one of these would scare the S*** out of me.

Can you say Iron Man?

@kimladha Can I get a set of plans for this project? I am having trouble understanding from your video. Much appreciated.

You should make a bug one and drop a car through it

wtf is this nerd...

[TheRandomnessofAandP]

that's pretty cool. sucks for me i have a phobia of hot metal XD all thanks to that one accident with a curling iron....damn 2nd degree burns...

gr8 set up man nice one!...now make a bigger one for a crusible and your rocking
