Resistive Spot Welder

Power Mosfets and a Bank of Maxwell Ultracaps Create a Powerfull Capacitive Discharge Resistive Spot Welder.

Version 1

I set out to build a Resistive Spot welder that could possibly even weld copper. not sure if it will or not as this capacitive discharge welder is back burnnnered at the moment. I wish i had got to test the jig.

this MOSFET switched capacitive discharge resistive spot welder project was intended for my use to allow assembly of quality lithium-ion packs from well-matched cells with reliable cell to cell welds.
