I made a perfect working spot welder with MOSFET switch. Easy to build and cheap.

I also ordered a batterybox from aliexpress for 45$ for my Li-ion cells. Want to build a 700Wh battery pack for my selfmade boat (size: 4m x 2m)

This is the battery box: https://www.youtube.com/watch?v=nqxY-899Rb8

I think it will not happen with this capacitor,if welding pure nickel :?

It works very good with 0.15mm pure nickel strips. I will upload a video in a few days showing how it works.
But if you need more power, a second cap is helpfull
