Nice and clever work congratulations! At red heat iron reaches the Curie point and stops being magnetic so re-tuning is needed to allow higher current withdrawal to elevate the tube to higher white heat . That is add/ remove more capacitors to reach resonance and pump higher currents for white heat.

"Polyester capacitors" are 3 pieces in series. The withstand voltage is 1200v, but how much voltage do you use it at? What are the actual resonance conditions?
Only if you added capacitors in parallel with the heating coil to tune the resonance to that at which the inverter is set. Even then, get it wrong and you blow your welder to bits. Try it and see. Regards MoK
"DIY induction heater by welding machine - Fun with electronic" on UA-cam has series resonance. The resonance condition is not well understood. Which has better results: series resonance or parallel resonance?
It's an electric universe. Everything oscillates at a different frequency. The closer you are to the resonant frequency of the material, the less energy you need to excite it.
Could this be scaled down (the coil part) to heat rusted studs and nuts on a small engine block? It could make for a great removal tool without the need of open fire.
The capacitors and the work coil have very high resonant current flowing. This is needed to make the strong magnetic field. The two turns of wire around the welder's inductor is only feeding the resonant tank circuit. That is why it can use only a small gauge wire. But the circulating current through the work coil and the capacitors are way higher. Think at least 10 times higher. That is why there needs to be so many capacitors. You need to split that high current among many devices.
uhhh idk how to precisely calculate that but the transformer rule is: more turns more voltage, less turns more amperage... so try with two, if too hot add turns, if too cold try going down to one turn. no, you can't use a 4,5uF 400V capacitor, you have to split the current among a lot of capacitors, or it will melt cause of the high current, but the voltage in game is very low so if you find a 200V or 100V capacitor it will go great.
@@tech.5137 the voltage applied to it will depend on the voltage output of the transformer. The current flowing THROUGH the capacitor should be minimal, even with a series resistor applied on the cap as a bleeding resistor. The current that flows from the transformer to the coil is determined by the entie circuit's resistance, you should be able to get a small resistance using some big diameter wire. EDIT: you can make 4 or 5 turns instead of two to get a higher voltage and so being able to transport more current through the wires.
The conductor wire coming out of the internal toroidal coil is about to touch the weld + wire. It is better to insulate it. The wire connecting the resonant circuit coil and capacitor is too thin. Keep the connection between the coil and capacitor as short as possible.
Hi Recalibrate & Every One, i have no basic in electro, i try to make as explained but it's shortage. I'm using 2.5uf Capacitor instead 2.25 uf, any body can help to assist me ?
What do you mean by shortage? Do you get short circuit? 2.25 uF is not a big difference, but the overall capacitance you use must comply. That means better get overall capacitance of 5 uF and try a large working coil (many turns) and thick wire. For example 2mm thick wire, 20 turns, coil diameter 55mm (5.5cm). Don't try large metal at the beginning and don't insert the metal deep in the coil, slowly when it gets red the curren drops then move it very slowly deeper in the coil.
very interesting! how many consecutive hours can it heat? I want to use it for a hydrothermal reactor (~12H of non-stop heating). do you think it's possible? THANKS
Excellent diy intervention.The welding machine is also ready to use.
Really cunning use of available things for reducing the costs
Hello, if the welding machine is still a welding machine, it does not lose its functionality, you would have 2 in 1, greetings

interesting. didn’t realize the capacitance could change the frequency, had thought that was a property of the inductance only!
Yes since resonance frequency is equal to 1/2π√LC
Please tell me if I want to melt non ferrous metals do I need to do all that you said . Thanks
@@drbeanut RCL, baby.

😂 good work sir
Can you tell me how induction heater work ?
Sergio, why not the LC circuit in series?
What if i'll made the 2 turns on the transformator to the capacitor bank from flexible insulated copper wire?
Prepare for the big bang and no more welder. Try it and prove me right> regards MoK
Will it destroy the welding machine after long use??
Question: Would it work it you hooked the electrode and clamp to the ends of a coil?
Only if you added capacitors in parallel with the heating coil to tune the resonance to that at which the inverter is set. Even then, get it wrong and you blow your welder to bits. Try it and see. Regards MoK
Please make more videos on this topic and details to build it
wonder can it reach over 1000deg with more turn?
one more turn will create less amperage, so... no.

The resonance condition is not well understood.

Don't bother if you want to keep your welder operational. Regards MoK.
hello there, how many copper wire turns it will take if the welder is 220amps? thank you
Good 👍👍👍
Thanks for your comment, greetings

Yes, coils can be made in the way you need
Handheld devices have been sold for that purpose for many years.
You would have more than a small fire if you tried it. Don't bother it's a scam, and a dangerous one at that. Regards MoK.
thanks, great video!

Can the working coils be bigger than that size?
The conductor wire coming out of the internal toroidal coil is about to touch the weld + wire.
It is better to insulate it.
The wire connecting the resonant circuit coil and capacitor is too thin.
Keep the connection between the coil and capacitor as short as possible.
do you know what voltage the two turn give ?

About 1/4 hour then get ready for the big bang> regards MoK.
Hello, please tell me the brand and model of the inverter.
Can you use copper pipe for the coil?
if you can greetings
Still don't understand how to build the capacitor bank 😔
Can you make video how to build it?
three capacitors in series, repeat six times. The connect them all in parallel.
it looks like a small welder if we use a biger one maby the effect is faster and maby melts metals
In my trial it produces very less heat what changes I should do??
try do a more short and little coil, this will decrease the area covered by the coil aka there will be more watts per cm^2 of steel of heat
When we remove job current is increases what to do??
It would work with any stick welder for example DC 220V
