DIY 600W induction heater

[tyreza79]

hi, very impressive,;

please can you point me to a useful circuit diagram vor en inverter that creats H frequencies ?

or point me to any site taht shows how to build one furnace !! i really need it at home to join things and build structures !!!!

thats for any help i have many capacitors, but i dont know how to make a frequency generator,

is it possible to converts the grid 220acv 60hz to a low voltage but high frequency out put ?

[dillinger9999]

but how do you make it?

[potroastmaster]

Does the ball bearing return to a shiny ball when it cools?

[RubieKitty]

I love aphex twin!

[ZEINSTAIN2011]

GOOD FOR MAKING NEW DIAMONDS!

[RamsesReturns]

I want one.

[randomvideowatcher]

The person must be in pain....he's melting one of his nuts.

[turgeo2004]

what is the best type of induction heater to get to melt (not just red hot) the following metals, copper, alum, gold, silver, and iron. (like in a crucible) so im wanting to melt the stuff in a graphite crucible and put the crucible with metals in it in induction heater.

[howtoguro]

For people who don't understand this think of this as putting your metal into a microwave it excites little particles inside and they bounce of each other, warming it like your food.

[jjppmm29]

yess indeed how do you make it....(missleading videos are the worst part of youtube)

[Teslavirus22]

HELLO

I AM INTERESTING TO MANUFACTURE IT.

PLEASE SENT ME THE SCHEMATIC AND ANY OTHER NEEDS INFORMATION ( SORRY FOR MY BAD ENGLISH)

teslavirus@centrum.sk

thank you...

[raininginhell]

What song is this. I like it!

[leandeganis]

isnt it enough hot to melt the metals?

[eloid777]

looking for plans to build one where can i get plans from ie free?

[ActiveStorage]

does the metal inside becomes magnetized too?

[uut0]

what would happen if i would put a superconducter in there?

[Arjoonmoal]

yeah yeah please share the schema pleas3e

[goatgodagain]

I've seen industrial induction heaters heat 1/4 x 1" bolts to orange hot in the time that it takes for the bolt to fall through the coil. Never could get them to tell me how many KW that sucker was! Beyond awesome.

[Usethebanana]

I love Aphex Twin

[jpmorgan187]

what did you heat up at the end?

[soymilk135799]

I make hot chocolate like this

[peteacher52]

My late father, a dentist, would have loved this device for melting the small quantities of gold alloy that made gold tooth restorations and fillings. Many is the time I watched him, in the 50's and 60's, with big gas bottles, lengthy hoses and the torch itself, as he melted the gold in the centrifuge. This induction coil would have saved time, trouble and been much cleaner! Your video has got me thinking! Cheers.

[hardstyle905]

@peteacher52 Yup. Science is simply amazing. Just for the sake of it it would be awesome to live forever.

[HorizonDelta]

Good video ! More Tesla video: "Tesla cold electricity" by HorizonDelta

[CsaptukEst]

Hello! Nice job! Is your schematic diagram a secret one, or could you please share that with me? (:

[ventHARAS]

nice musik lol

[frank0067]

i think its a cue to a puzzle we are supposed to figure out ourselves...

whats the prize ??

[43932]

Waw ! I'm not the only one who love AFX, forging and induction !! :-))

[conclavian2000]

I like the music. Who is it?

[peanuts2105]

@conclavian2000 Xtal by Aphex Twin

[themainproblem]

@conclavian2000 I thought the music was really cool as well. Who was that?

[marieomagpie]

should be able to melt aluminum and maybe some brass.

[TheNengChang]

Wouldn't his be dangerous since it sits out in the open without any safety guards?

[WpA09]

i think it is hot

[Fourteen88SoCal]

....what's the point, just looks dangerous....and don't get me wrong, i love fire and blowing things up just like every other guy but this just seems pointless to me

[deliquenme]

600Watts? Could you make a water heater with induction coil? And as I see there you need something much smaller because you will make steam with that not hot water :D. That is just a guess.

[TeravoltOrg]

@deliquenme

Water's not conductive enough.

[deliquenme]

@TeravoltOrg What if you heat a pipe that circulates water?

[TeravoltOrg]

@deliquenme

There's still no point in induction heating. Just heat the pipe resistively.

[deliquenme]

@TeravoltOrg Resistively with 600W of power? I don't think so...

[TeravoltOrg]

@deliquenme

A typical electric water heater runs at anywhere from 900 to 2500 watts.

[deliquenme]

@TeravoltOrg An instant water heater runs at 2500 Watts-6000 Watts, that was my point, instant hot water at the flip of a switch with low power.

[ApostleRon]

why do you call this DIY? all this video shows is you heating stuff.

[hellsundeadarmy]

What if you tried to have sex with this?

[extra3Fan]

hahaha, great! :-D

[manikase27]

cool!

[BozznoQ]

That's so HOT!

[e39dreamBITCH]

aphex twin FTW

[Agentoxedo07]

Holy-Terrorist:>-^=^- Cool music !

[Arjoonmoal]

oh my god my caps exploded into my face using a ZVS driver luckily i was wearing spectacles. feel sorry for my spectacles that i paid so high

[DigiDavidex]

0:52... WOOOOW

[ronwire182]

whats the song name and can u please post the circuit diagram

[lapulapu12345]

GOOD for identifying GOLD BARS whether it is fake or genuine :D

[srm13560]

one hopefull question: can i use a stereo system to power this, since HF is in the range of audio?

[HVdischarge]

Could you please tell me where you got the capacitors from for this? or atleast what type of capacitor you are using? (and how many)

i am using the ZVS driver as an induction heater driver, works fine apart from the fact that after about 10 seconds my caps are on the verge of melting!

1 capacitor decided it hated life enough to blow and make loads of mess :-/.

Thanks,

Hv discharge

[tonskulus]

@HVdischarge

I think those caps were Wima FKP series, maybe 5 x 0.22µF..cant remember. Now I'm using plessey KP capacitors, 14x parallel connected 0.22µF/1000Volt.

[HVdischarge]

@tonskulus Ok, Thanks.... 14!!!

maybe thats the problem, i was using 6X 0.22uF, 400VAC caps.

Maybe i will try throwing a few more caps on there.... :-/

[conclavian2000]

Very interesting video! I had been considering refining gold at home and wondered how the hell I would get it hot enough to melt. What exactly would it take to melt gold this way?

[DaemonAnt]

What would the uses be for an induction heater?

[38828601manu]

does it liquify anything?

[tonskulus]

@38828601manu

No this one is not that powerful, check out my other induction heater videos..there is more power and almost any metal can be melted.

[38828601manu]

@tonskulus anyway it´s awsewome

[pastorrtom]

Lovely music!

[redsquirrelftw]

That's awesome. How do you convert 60hz to higher frequency, and how do you make it so it's not just a dead short that tripps the breaker? This looks like it could be fun and useful.

[tonskulus]

@redsquirrelftw

Its using inverter that converts DC to 70kHz AC. Its not even close to short circuit for this high freq.

[dmaas44]

Nice job! you should make an instructable for this... Good music too! :)

[lazzi1996]

that coin looked awesome

:D

[MrNachtlich]

should only label your videos DIY, if your actually showing someone how to do it themselves not you doing it yourself.

[Angelo8698]

Olá you could send me a drawing of the circuit project so that I can make a system to heat in high frequency.

My email

[jokukas]

Will it work for heating water really quickly?

i have one experiment that needs to get water boiling really fast

[tiger182281]

is there a tutorial somewhere on how to make one ?

[tiger182281]

would this work for forging? especially making swords?

[tbsys31061]

@tiger182281 yes, there are professional versions of this.

[tonskulus]

@tiger182281

Sure, may just require more power. 600W is not much.

[FLswamps]

I was just looking at these coils and noticing how exorbitantly expensive coal is getting. Of the 20-30 smiths I know, none use this; but I need to run some numbers on electricity costs before I shift my knifesmithing heat source from coal to electric. Man, would it be nice to lose all that coal dust and smoke from my forge!

[RODALCO2007]

Excellent video. what is the name of the music ?

[arsesto]

@RODALCO2007 Aphex Twin - Xtal

[RODALCO2007]

Many thanks

[ChilesGreen]

Does anyone have a link showing a schematic and list of components to build an induction heater like this? One of these would come in handy for soldering and brazing.

A word to the wise never put your ringed finger inside one of these;-)

[0815tobey]

Awesome! 0:55 looks like the sun is rising ;-)

Does this actually work with all metals???

[TheTruthPusher]

No Calle, but it does mean you can heat you home

for much less than what you've been swindled out of so far.

[Calle2k]

I guess this does not work for melting metals like you see in those homemade (metal melting) foundry setups..?

[tonskulus]

Well, this one has too low power but I can also make bigger ones for metal melting. Check out my other induction heater videos!

[kommodorez24]

so? how the fuck do you make it? show us some scheme or something.

nice done by the way

[GrandpaTD]

How did you make it and where did you get the parts?

[tonskulus]

How do we generally make different thing?

Ok, I had these parts laying around. I have lots of electronic stuff.

[gixer912]

who do the parts holding the object inside the coils not get hot

[hughheckler]

if you ran water through a copper pipe inside of that induction heater coil, recirculated it back through a few times, how do you think it would heat water? or is there a risk with the electricity involved? I don't know a whole lot about these, but they seem quite interesting.

[codex653]

it only works with metal, that's why it's called an induction heater. it operates on the principle of inducing a current into a metal

[Envergure]

Best part was the penny oxydizing at 0:52

[laurdy]

i would have used tongs to drop the ball bearing at the end into a bucket of water

[Crouton351]

1:38

IT'S A DRAGONBALL

[gurnaim25]

hey how do you make one? because i like to have one of those.

[j822bosh]

Well these seem complex but if you break down the major circuits and concentrate on each circuit individually them hook them all up then its not so bad! Some believe this works only ferrous metals but I have seen it work on copper, aluminum, and graphite. Would work well in chemistry so one can heat a reacting metal inside a tube without open flames and probably get more complete conversion.

[tonskulus]

Yes, indeed it heats any metallic objects. As can be seen on this video, starting at 0:27, there is copper coin to be heated bright white. Check out my other induction heater videos.

[AlexRGravlin]

What happens if you put your finger in the middle? Seems like it wouldn't do much.

[tonskulus]

Nothing happens.

[AlexRGravlin]

Thought so. Seems like the electrons of metal would be more easily excitable.

[juliman12]

im thinkin bout makin one of the thingies could i just coil up some copper wire (tubeing) then hook it up 2 a car battery

[tonskulus]

Yes, sure!!!! Looks like u want to melt that copper wire.

[spinctah]

Dude, you shouldn't be allowed anywhere near wire or car batteries! lulz

[Alexselectronics]

That would just melt the copper wire and could destroy the battery. Induction heating requires high frequency alternating current from an inverter, not direct current from a battery.

[jmckittrick1]

Do you have a schematic for this heater?

[tonskulus]

There are many similar schematics available on internet. I dont have schema.

[xtalgrwr]

Do you think you could give us an instance? Your setup is nice in that it is only .6KW but for my need the frequency is too high. Nice.

[tonskulus]

Check out my other induction heater videos too.

[hellomate639]

Can you make a 1200 degree one that can run on a lightweight battery or high energy capacitor?

Reason is, if you can do that then you can make a lunar forge to turn the regolith into a construction material.

[438426x1]

i'll only be impressed if they get metal hot enough so it glows purple

[tonskulus]

Check out my other videos, melting metal is pretty bright. This video shows only my very first and low powered induction heater.

[Desmonddd2002]

I currently want to build one of these cool stuff.

Can I use a FBT? (The old ones that gives out AC)

They work in relatively higher frequencies rite?

[tonskulus]

FBT itself is not induction heater. But it can be used as a part of system as Lmatch coil or matching transformer. U just need to rewind it..So only part that can be used is the core itself.

[Desmonddd2002]

thx.

[laurdy]

the ball bearing at the end looked a bit like a cherry

[n00n0788]

I don't understand. What's an LCLR circuit? I thought induction heaters used LCR circuits. Do you have 2 Inductors?

[tonskulus]

Yes, two inductors. Impedance matching coil and work coil. Zmatch coil is between inverter output and tank circuit.

[Alexselectronics]

How do I calculate the value of the Zmatch inductor.

[tonskulus]

series cap and inductor values are chosen so that it is resonant above operating frequency. Usually 1...10µF and 10....200µH range.

Its also possible to make it resonant at third harmonic of the operating freq to allow full power from power supply to the tank circuit.

[dublt36909]

what was that last thing???

[tonskulus]

15mm diam. Steel ball (from ball bearing).

[citydriver]

how the hell is that possible the part isent touching the coil and why isent the coil redhot?

[matthewjohnmcgee]

The coil produces an electro magnetic field. The molocules in the metal act as a resistance medium for the electro magnetic energy. As a result the metal becomes extreamly hot.

[citydriver]

sounds like something out of science fiction

[matthewjohnmcgee]

It's a little complicated. But the coils are made of copper which is a excellent conductor. When high voltages flow through the coils, the electro magnetic field causes a thermal reaction on a molecular level, to were the molecules developed their own magnetic field. They repel each other. As a result the object becomes white hot very quickly. The reason the coils them selves dont become hot, is the energy flowing through them is transferred to the object through high em frequencies.

[vodasdesign]

Hello,

Very interesting experiment.Congratulations.Wha­t do I need to build this kind of heater ?

 Thank you very much.

Florin Voda

[tonskulus]

You need variable freq oscillator and halfbridge power stage to drive LCLR tank circuit..

[necrogoat]

Thank you for your answer.Now where can I find these parts? All the best.

Florin Voda

[ratheads]

MMmmm... roasted nuts.

[HYPERmax9000]

It is a good idea to induction heat it?

[RODALCO2007]

Awesome experiment, awesome music.

Thanks !

[AFX86]

APHEX TWIN FOR THE WIN!

[nickp1987]

Random thought, but it seems like something like this would be ideal for someone who forges knives and doesn't want to deal with the hassle of a charcoal forge.

[tonskulus]

yes, indeed. Knive factories/industrial are using induction heaters btw..

[venomousbird]

I just watched a video, and had the exact same idea. Now to work out a silent means of hammering!

[johnbunsenburner]

hhm, i think you build your self an electric heater, and induction heater works totally different! Doesn't matter, what can oyu melt?

[johnbunsenburner]

what else did you use to build the heter, just list the things will you.

[johnbunsenburner]

well wh are you using nichrome? Is it especially good or did you choose randomly?

[johnbunsenburner]

what you have in water boilers is nichrome...?

[rainmanp7]

wow dam nice :)

[LizzyAston]

What are the components needed to build the circuit?

[Licurgoknox]

good song

[johnbunsenburner]

And how can i get the 240v from my power supply "high frequency" Or is it already, i am guessing high frequency is fairly relative.

[tonskulus]

Sorry i dont understand.. You have somekind of psu giving 240Volts output? Induction heaters has frequencies in range of 5...500kHz. Lower frequencies are used for deeper heating effect and big workpieces and higher frequencies for small workpieces and surface heating.

[johnbunsenburner]

really i want to melt aluminium wiht the heater, i have 240volts coming from "the wall" but have no clue about the frequency, wattage or the amps...

[tonskulus]

Ok. Maybe you should buy commerical induction heater, check out eBay.

[johnbunsenburner]

arent they really expensive?

[sjfperformance]

Can 120V work? Can it boil/heat water?

[tonskulus]

Its not about voltage but power. But ok, at least 12Volts is required. Yes, it is possible to heat water indirectly (water is inside of metallic bowl). You never heard about induction cooktops? Its the same thing.

[ChrisKarr]

Is induction heating done using only DC? Or is AC used, as well?

[tonskulus]

Induction heating is done using highfrequency AC.

[anon32016]

It's very high frequency AC. The phenomenons used are eddy-currents and magnetic hysterisis. Wiki them for a better explaination.

[peterban1234]

Try to heat a small CO2 cartridge.

[ford65falcon]

How simple is this to make. can u send me some kind of instructions to construct such an induction heater?

[deathadder32]

wow that would be perfect for forging knives...

[Deadzo]

Yup. Then just start up a small charcoal fire in your forge & let it burn down, temper the knife in the coals (if you used induction to harden). Or heat, quench, let it sit in the coals till they burn out.

Only thing I cant see using induction for is tempering; takes a few hours, just do above.

[zephroth]

or he could melt a salt to temper with the induction heater XD. but then again thats a long process XD

[tTatmosT]

yea and no need to burn so much coal to make one lol

[kydoes]

That sphere (Mouse ball im assuming) looked awsome

[Gunstar1986]

awesome video!!!

btw whats the song?

[cornflakes002]

Gunstar1986

Aphex Twin - Xtal

[66gfr33]

our indutions header in the company has 250kw

[frizspin175]

does the coil have to be cooled?

[tonskulus]

Cooling is recommended for 100-600W powerlevels and absolutely required if >1kW. Otherwise workcoil will melt sooner or later.

[HLSDK]

smells like some aphex twin up in here

[Ztuibyman]

Cool, i mean hot... I wish i had one of those things..

[jster1963]

Hi,

I'm a novice and want to make an induction heater like yours. How can I get the plans and components? Any help would be appreciated.

Thanks....jster

[98209276]

do you have the plans it looks like a sstc sign wave driver lol

[tonskulus]

Yes, i have plans. How can i make these without plans anyway?:) It is mostly like those basic sstc's - signal generator+gatedriver+halfbridg­e power stage using small 100Amp IGBT brick.

[mavamaarten]

that's HOT =D

[tonskulus]

It is hot, but still too slow for heating some heavier stuff. Im working on with new setup. 4 x more power.
