One ruined screwdriver

@TheLightningStalker if I remember right, this screwdriver was defective from the box. The head was only rounded instead of shaped to turn a screw.

I Will be thank full to you if you answer a few of my questions

Q: What is the tank Cap value?

Q:How many amps iz the PSU out putting on the 12 v rail,15 or 25?

Q:do the MOSFET's get warm?

Q: how many turns are on the inductor u use?

Please answer my question i am having a really hard time figuring this out!! :(

@Salarbs I think that was a 2uF capacitor. I don't remember the current, I think it was around 10 amps. It was the 12v rail of a computer PSU. I just put as many turns as I could fit on a iron core toroid from a computer power supply.

The mosfets get quite hot here, but I found out it was because I somehow used two different gauge wire for the work coil. It runs a lot cooler when you do it right, and use longer wires leading to the coil. like in my other induction heater video.

@compwiz00 Using longer wires reduces the current. For best results, use as short wires as possible and put the capacitor the nearest possible to the induction coil.

My induction heater ZVS needs 20-30A at 12V, but has also a bit more power than yours.

Using longer wires results in less output power.

@Elektrobastler That's true. But more power also means more heat for the electronics. I was having issues keeping it cool with extremely short wire. I would try it again, but I've managed to light something on fire almost every time I play with it. I need better parts, I think. In this video, I'm pretty sure that power supply will only give 15 amps.

Yeah, this thing draws about 20 amps at 24v, from batteries when powering a TV flyback. The arcs melt steel hanger wire.

howi is the tank cap connected. is it parallel to he work coil or is it in series. i have a very big 10uf 450Vac mkp capacitor will be good. i mean the more capacitance you have is the better or it should be within a range of values

@compwiz00 can such a circuit be made to fully liquidise metals? like aluminum?

@Audi100C4Owner Dude just pace what ever u uwanna heat in the center tapped primary of the zvs instead of a flyback transformer
