How To Make An Induction Gun (Bolt Heater / Buster)

Link to wiring diagram & STL file for 3D printing the handle: drive.google.c...
Parts ordered from eBay.
Use the following lines to search for the components I used in the video:
"ZVS induction heater 1000w" - Induction heater with fan, 12-36VDC, 20A
"Switch power supply 24v" - Power supply, output 24VDC, 33A
"buck converter lm2596 adjustable" - Buck converter. Used to drop the voltage from 24v to 12v to drive the relay & LED
"12v 40A relay" - Basic automotive style 12v relay (recommend buying a 24v relay because it would eliminate the need for the buck converter. Note: if doing the aforementioned replace the
1kohm LED resistor with a 2.2kohm resistor)
"1/2watt metal film resistor" - (either 1kohm if using the 12v buck converter, OR 2.2kohm if running the LED directly from the 24v PSU)
"push on-off latching switch" - basic latching switch
"5mm LED mount bezel" - used to mount a 5mm led to the enclosure
"5mm led red" - The LED I used was rated for 3.2~3.8v and a max current of 20ma
"8GA wire" - Insulated 8gauge copper wire (I used about 3meters (or 10ft) total length)
"c14 socket" - look for a C14 socket with an integrated fuse holder.
"5mm fiberglass sleeving" - I bought sleeving with an internal diameter of 5mm. Buy about 2meters (6ft) worth (its cheap)
"Split Conduit" - Split cable sleeving to fit over the 8GA cables that go to the handle (20mm or bigger dia, 1.5m long)
"female spade terminal crimp yellow" - Used to connect the 8ga cable to the relay.
"3 core mains cable" - I used less than 0.5m (1.5ft) rated for 240vac, 10amps
"cable gland PG9" - quantity: 4
Optional:
"5mm copper tube" - 5mm dia, 500mm long (1.5ft) I used this to make the 2nd smaller coil in the video

    Verbal typo at 19:52. To clarify: THIS induction heater won't heat non-ferrous metals. It's just not powerful enough. For heating non-ferrous metals like alloy, brass.etc you need a more powerful induction heater and also the coil frequency plays a major role when heating non-ferrous metals. Sorry for any confusion! - SCHEMATIX -

    Nice build.. I am a noob on the matter and its more the concept that appeals to me... so pick up a cheap edition that cost around 3.5USD and been playing with it the last couple of days,. i.imgur.com/6lMr8mP.jpg Was planning to make some recording with thermal to show how the heat transfers and I atm I run it on an adjustable power bank that tops out around 80watt, but for proof of concept and small metal pieces its work brilliantly.. form a 3.5USD product it is able to make fx a 5mmAllen Key completely red glowing, solely from a USB(DC) powerbank.. DP my bad. Have you validated what kind of watt you are able to deliver with your setup and if it's loyal to spec' hence 1000w. would be very easy to put a basic watt-screen in your big casing and also give you a good indication when its in fact heating and when your holding it ideally on the mark' as that can vary greatly and here that amp current-info value is a good indication, for when its done heating and close to topvalue as it will then start to go down' and you don't have to hang butt naked in no mans land, if its heated or not or start looking for glowing identification' that can be difficult to see under some scenarios.

I found this video after watching a tool demonstration for this tool by a manufacturer who wants over $600(USD) for it. I figured thier profit margins are pretty high as well as the 3rd party who likely manufactured it for the seller to slap thier sticker on it and call it thiers. Anyway great job man!

    You can certainly induction heat non-ferrous metals like brass aswell. While not as effective as iron or steel because of no heating due to hysteresis losses and relatively low resistance in the material itself, it's definitely possibly, what really matters is if the work piece is conductive or not.

    not sure if were on teh same wavelength but i modified the ZVS itself with some 2n2222 drivers, slam the gates hard and keep them saturated. rather than the lousy 5w resistor they standardly use. problem with ZVS is they dont like suddenly changing component values. things like, perhaps, sticking large bolts into coils whilst running. that ALWAYS resulted in fets EXPLODING on me... no smoke. no heat. just shards of epoxy encapsulation suddenly sprayed across the room. putting stuff in the coil THEN powering up was fine. they only like steady constant loads. abrupt changes whilst running... BOOM.

    pro tip to make this just a tad bit better, move the capacitors closer to the coil at the handle bar, the current resonates between capacitor and coil, only a little gets added by the mosfets, the way you have it right now, all the current is circulating in the cableling to the handle aswell! if the capacitors are right next to it, it will work better and be more efficent. also edit, at these frequencies (likely around 100khz, the more caps the lower the frequency) 10sqmm wire isnt the same as 10x1sqmm (skin effect) use multiple thinner strands.

    I'm literally in the process of making my own. I got a 48v version and a big psu. And a 48v relay. Nice handle. I'll be stealing that. Mine heats up an m10 bolt I about 10 seconds. You I've got it so my psu is always on and then the relay applies the power to the circuit board when I press the button. The problem with leaving the circuit board constantly connected is in the few seconds it takes for the psu to fully turn on. The circuit kicks in, doesn't have enough power to start oscillating and pretty much makes a direct short and blows itself up. Just in case anyone is thinking of making their own.

    This is great, thank you! I had the misfortune to have a need to remove a nut from a 40 year old suspension strut in an enclosed fibreglass space. I had nothing that would work since it needed held in place by a 9/32" crescent spanner whilst a 9/16" ring spanner tried to unsieze the nut. Suffice to say the tiny chamfer started to round off first. My local garage lent me their induction heater, and after a few heating cycles and penetrating fluid, the nut came off with no struggle at all. The induction heater is an absolutely fantastic tool for anyone working on classic cars. I'll be building one shortly :-)

    A cigar lighter heats up due to the coil resistance when 12vdc is applied, and it's coil is specifically made to withstand repeated heating. Induction heaters have no physical contact to the target material, and only heat up slightly. As seen in the video (17:50), the bolt reached nearly 800 deg F and the coil only 150 F.

    This is a fantastic little tool. I could do with something similar when replacing the AFR sensor on the car. I would add protection to the Relay to prevent Back EMF from damaging the Buck Converter. Unfortunately this is not a good DIY project in Australia due to our laws about mains power and requiring a qualified electrical contractor to do any wiring. Unfortunately, no matter how talented someone is, this makes it prohibitive to do as DIY here. Thanks for the informative and well laid out presentation video. That insulation twisting trick works really well on finer gauge cable as well. I recommend it as not only does it twist the cable well, it avoids oils from the skin getting on the cables.

    Yes. Induction heaters work by inducing an electric current (eddy current) in the work piece. It should heat aluminium or copper faster than steel or stainless. Keep your gold and silver rings well away from it, especially if on your finger. SERIOUSLY that is DANGEROUS!. Also, the cables leading up to the trigger should be twisted and held tight together or you will lose a lot of energy from magnetic loop losses.

    You need to heat the nut not the bolt because heating expands the metal. I would need to try it, but i still think a torch is better for automobiles. There is situations it is critical you get the bolt out successfully without damaging the threads in the tapped hole. And if you melt the head of the bolt off, you're screwed. If there is something in the way that will burn, then remove it, or put heat shield between it and the heat.

    Tons of useful information here. Would you have any insight into what it would take to heat brass bar? Less turns on the coil? Higher frequency? edit: I know you mention in the end it won't heat brass, but induction heaters are used to anneal brass bullet casings, and used to heat copper pipe for creating clean solder joints. I would guess by the use of eddy currents?

    While you certainly can use induction to heat those metals. The induction gun I built in the video has little on brass/copper. I think it's just not powerful enough. The manufacturer claims the unit is rated for 1000w. However, I've only got it to draw around 300w. If I stuffed the coil to the point it's bursting with metal then perhaps I'd be closer to the claimed 1000w. So in summery, I think a more powerful induction heater would be required for metals like copper/brass.etc Perhaps a future video?

That tells me that it will only deliver ~1000w if you use a ~50v supply. It also suggests that at lower voltages you are unlikely to need a 20a capable supply - as your own measured 300w consumption confirms.

    The size of the coil is fairly critical to achieve maximum output. Heating up a bolt to a few hundred Celcius isn't very hard, so tuning the coil isn't strictly speaking necessary. However for melting metals.etc requires much more than just guesswork. FYI: For tuning a coil you'll also ideally need an Oscilloscope & signal generator.
