In a forward converter, you MUST NOT use an air gap in the transformer, it increases the leakeage inductance, an thus the flyback current (in the reseting system), decreasing the efficiency. The airgap is only used in the flyback converter, because the energy is stored in the transformer, in a forward converter, the energy is only stored in the secondary inductor. The schematic looks good, nice job :)

Air gap is used in the forward converter to reduce the remanent flux of the core allowing more usable flux density 😉

I really love this series about welding inverters, thanks

How cool is that !

Cool. Good luck. 👍

Great video Sir!!!

Thx Bro

Choke is not needed if you constantly weld on high currents, but under low current settings, starting an arc without a choke is rather hard

You can get CREE MOSFET modules.

Wow!

I love how the comment section is also crowd-and open-sourcing a better welder than some you can buy 😆 Gonna try to go even further Kasyan, home-build a MIG/TIG torch next? Or go for a cutter instead? Honestly you could just make anything and I'd be interested at this point.

Honest amps... I like that word

I bought Kzubr 400N is it any good? From the label it states that it pulls 35.7A with high spikes of 47.5A! It welds very well but is there a way to adjust the LCD screen to show only 200A since as it is it goes up to 400!

what if i want to install igbt 60n60? Is there a circuit component that has been changed

That thick "paper" insulator in the transformer is called "fish paper". And no, I have no idea why that's the name.

olá eu sou do Brasil, por gentileza você poderia me dizer onde eu compro IGBT originais?

what if the 24v is not operation?

👍👍

I am working on welding inverter project, Can I get a schematic of professional welding machine?

Rename the video to : Making a Welding machine better then factory one 💪👌

Hi kasyan

I need that PCB design file 🙄

Anyone have an idea of using something similar to charge my old car that needs around 200V? No need for isolation between primary and secondary. I thought about rectify the 3phases and use some kind of PWM to limit the current. Is that the way to go?

how the heck does you car need 200v to charge up? usually there is just a 12v vaterry

@@Frolleglse well if you need exactly 200v you can use a variac and a bridge rectifier with capacitor to output 200v stable, if you dont need exactly 200v you can just use mains witg a bridge rectifier, that will output 200v rms with peaks of 325v

Unfortunately a transformer will be so big and expensive. Must be some switched power supply or PWM of rectifyed mains. Cannot rectify mains directly and feed the battery since the current would be enormous in such setup.

'an' only goes before a vowel. So, you title should be" 'Make a Welding Machine not worse than the factory one'.

Before a vowel sound, even if the word starts with a consonant when written.

There are so many components. Often it may end up with repair.
