Hello All,
This is a spot-welder project that i plan on starting, now in the design phase. After a spot weld is done there would be some voltage returned to the ground plane so should it be connected to the common GND or via a 10k resistor. Its obvious that the MOSFET would need to be conneted to the GND without a doubt to complete the circuit but just curious to know if there is any advantage of adding a resistor from a N-MOSFET Source to GND. The voltage from drain-to-source is 8.1(MAX) from ultracapacitors in 3s2p configuration.
