What kind is that , inverter or transformer ?

@@funwithelectronic4140 It's old so it could be transformer might not work for it :\

Transformer not work . But you can find old inverter and make this .

Yes . I do as soon as possible.

I'm waiting too

Assim que tiver ficaria agradecido também.

It's been almost a year where is the diagram block

the welder is just a power supply. You still need the rest of the switch and caps to create the right frequency. or just buy it made ond use the welders as a power supply.

No. The strongest field is in the middle.

@@funwithelectronic4140 ARE YOU POSITIVE????? There is mathematical proof, also numerical and computer simulation (based on the BIOT-SAVART LAW) that strongly suggest it is nearer the inner edge, more specifically, being at a locus of points forming the "circle of MAXIMA" around the exact inner center of the coil. In fact, the weakest flux density is at the very end of the 'centers' of the coil (two points), where the flux here is exactly half that at the middle center axis.

I see that where you place a piece of sheet metal over the coil, it heated far more along the outer coil area. I think this isn't just from a hot coil, but from the much stronger magnetic field at the edges of the inside of the coil. To test this very simply, insert a fireproof sheet between the coil and sheet (or just hold it slightly above the coil). You should see that the max. induction heating is due to the field being much more intense at the INSIDE perimeter of the coil.

Abang paham cara buatnya ya..tolong bntu sya bang 🙏

Yes . It can

You can use any chopper. 4 kw

@@funwithelectronic4140 thanks for the reply

لا أظن ، لأن ماكينة اللحام معمولة فقط للعمل لبضع ثواني

4kw

Hi . It is black hot glue. Usually Used by hot glue gun.

Yes . By 12v simple water pump

how many smd resistor code did you throw away?

Hi . I don't measure the inductor . Inductor is 7 turns. two turns wire belongs to transformer. Transformer is 20:2 .

Connecting the TV flyback transformer is possible, but it will probably burn out when trying to obtain an arc due to the high power of inverter welder. El posible conectar ed TV flyback transformador pero probablemente se quemará al intentar obtener un arco debido a la alta potencia de la soldadora.

Misteeeeerio, kkkkk

wha? whats so critical about seeing some pipe get bent? if you cant figure out how to wind a bit of pipe through a toroid (and anyway, its better to used a gapped ferrite core, not a toroid) then maybe you shouldnt be contemplating projects that require dealing with copper pipe...

description clearly states its for frequency change...

Hi . Which part do you want information about

Hi. Driver chopper doesn't have enough power . Wires connect to transformer output. Thanks for comment.

Hi . The freq is 60khz , yes sin wave

Hi . Thanks for watching and comment. I will if I find an old induction stove.

I have a old induction stove, the problem is that I have read that the coils are at potential....

That resistance set the frequency of switching. the frequency must set to resonance frequency of tank RC.

Use a material that attracts magnets such as iron. Copper is non magnetic and takes a longer time and needs more power and higher frequency mainly because of the thermal conductivity of copper is so great.

Yes . It can

how many smd resistor code did you throw away?

There is no problem if capacitors and coil cooled.

2500 c

Hi .no load Frequency 60khz and current 35A .

Hi . For freq adjust. See comments please.

@@funwithelectronic4140 pls schéma

one resistor . freq adjust.

@@funwithelectronic4140 what is the voltage code for the resistor you unplugged?

Hi . The pwm ic is uc3846 in this machine. Pin 9 of ic is Rt for frequency adjustments. You must throw away this resistor and put the variable resistor .

@@funwithelectronic4140 that you connect to that output from negative positive ct or rd ?

I'll upload another video with full details in a month.

​@@funwithelectronic4140уже год прошëл,а где же видео?

Hi . Pin 9 of ic(uc3846) . For freq change to resonans

@Mahmoud Raddad duty cicle it's fixed to 50%, about the frequency, give a look at the datasheets and use some math

60khz

i will made it soon.....thx brother...great idea

Hi . 20 turned in primary

how many smd resistor code did you throw away?

I dont know your language. Please ENG

I want to heat it upto 700degree and want to add automatically timer switch to stop it

Please reply

hi Please come funwithelectronics22@gmail.com

Yes . Up to 300 gr copper .

how many smd resistor code did you throw away?

Hi . Black and red cable connected to oscilloscope . For reaching max amplitude (by variable resistance tuning)

The black cable from chopper (300 vp-p)

And the white cable is secondary of transformer. Transformer is 20 : 2

choper out ussualy have 4 pin out, 2 red pin out and 2 black pin out, every two cable red or black is conected together? or you just put in one black and one red pinout? because if you jumper 2 black chooper output it will make double 475K red ceramic capasitor from mosfet or igbt

very clear explanation, i thinking before red and black clips is feedack current sensing...in fact it's connected to oscyloscope 😁

Hi . Please comment your phone number here , for sending schematic.
