Spot welder
with Super Cap 500F as energy source with over 300A current


Choose transistors with a low Rds <10 m Ohm, e.g., IRF3205 (8mOhm )or similar
I use  4x  Irf1404 (4mOhm)

I built this circuit in real life.
Here's my improvement:
Connects three capacitors in series.
This increases efficiency. Connect a resistor in parallel to each capacitor.

8v power supply required to charge the caps
