Capacitive Discharge Spot Welder
If the weld itself has a resistance of 2mOhm, then only ~22% of the energy stored in the capacitors is transferred to the weld. Another requirement is for the weld pulse to be short. Ideally, this will be on the order of 10ms to prevent heat from the weld conducting into the cell and increasing the size of the heat affected zone.
