Mini Spot Welder from Aliexpress

[hojnikb]

So there seem to be plenty of those kWeld clones on aliexpress including this https://www.aliexpress.com/item/1005001492794726.html?spm=a2g0s.9042311.0.0.53154c4dCZc8CF(link just for reference)

It seems to be pretty common knowledge that these have a high chance of blowing up mosfets due to poor design. Someone seem to found a fix

But it looks like there is already a new revision floating around and this is the one i got

Capacitor fix seems less obvious to me. Anyone played around with these newer ones and knows a fix ?
