DIY induction heater testing

[KrankySourPants]

All that heat. I have an idea how hot that is, I used to weld at a tech school. That's kind of scary considering I didn't see anyone wearing gloves. Doesn't that hot metal or the process of induction heating emit UV rays? I know in welding the UV rays from striking an arc was part of the reason why we'd always wear a cape, bib, and helmet.

Free sun tan? :D

[marieomagpie]

@KrankySourPants I don't think there are any dangers of UV rays because there are no electrical arcs

Хм прикольно

i wouldn't put my finger down there :P

[natn0]

unless you have metal in your finger I wouldn't worry about it.

how do you coil the copper pipe?

1:38 reminds me of Sonic.... lol

[LizzyAston]

i really want to have one but i dont know how to build one....

[montysilo]

what song is that?

[ApLsToApLsOs]

How do you make one? Take a wire with a big battery and pass electricity through?

Power is taken from mains. It is converted to high frequency AC (around 50kHz) and it feeds tank circuit, parallel connected capacitor and workcoil. When this circuit is in resonance, there is huge circulating current. When workpiece is in workcoil, it induces eddy currents for workpiece. This current will heat up workpiece.

Can you email me a schematic?

[LeviMan2001]

so is this an osilator like the kind in a synth? or the kind like in ac electricity

[tonskulus]

This is vacuum tube oscillator type heater.

[MOJTABASHOMAL]

can this induction heater melt silver or gold?

[LeviMan2001]

i don't see why not

Induction works great with magnetic metals. Some work feebly on small amounts of non-magnetic metals, not sure how though, or the specifics.
