I'm so happy to have stumbled upon this channel. It appears your interest in welding inverters is fairly recent. Can't wait for more! Theres so much practical detail in your videos, thank you so much!
Some how forward topology work better then halfbridge converter topology I had the same issues when I made my first smps welder but a voltage feedback can be added to allow the halfbridge converter topology to work properly 37% duty cycle 62 voltage and at 50% full duty cycle the voltage with go 100 volt so the welder dropout voltage with no be 15 voltage but 26volt
Just a gentle note on pronouncing the word "gauge" as "gage" as it is confusing to Americans, we use Gage in Industry to avoid problems. (English Spelling does not Match Spelling)
How do you get 4kW through a Schuko plug? (or rather even more than that, because the 4kW are the output power, not the input power of the welder). Do you have a 20A fuse on a 230V circuit?
From what I heard, there are different regulations, depending on the country in terms of how much power is allowed to be drawn from an AC wall plug. So, in USA, you can't find a 2kW water boiler. While in Germany, a 2.3kW device is not a problem, and my hair dryer draws 1.8kW. The limitation is given through the fuse for the circuit that you are using, and (even more important) your wiring! When pulling so much current, the voltage drop across the wires in your walls matters, because the power of dropped voltage•current•√2 = P is dissipated as heat across the resistance that is given by your wiring. If it's too much, something's gonna melt, short curcuit, there will be sparks, and maybe a fire. But if everything is alright, then you can draw as much as you are ready to pay for :P
@@oilybrakes Yes, I know that ;) . It's just that Schuko plugs are rated for 16A max (and not even designed to run that continuously), no matter how good the wiring before that is. Of course you can draw more, but that's what the fuse would be for to never allow that, because otherwise as you say melting, smoke and fire. So there has to something dodgy going on if you can get 4kW output on the welder. It shouldn't have that plug in the first place.

Really enjoyed your practical example of test jig design and rework of a low performance inverter…keep it up..well done..
The balast shunt is use on what? Can find one on a flea market

Have you produced the video for modifying this welder yet? I'm quite interested in that.
What about connecting a spring type heater coil instead
Really interesting project, dude! Fantastic! 😃
Can you give me the value of shunt resistor paralleled , and no of Schottky diode,

Привет Касьян.

( добавить артикль "а" )
А так, все отлично!
спасибо , изменил
I need one to buy
Muy bueno!
you voice so sweetttttttttt
