Simple arduino code that reads the state of DIP switches and send 5-70 ms pulse to car relay for spot welding.
I do not recommend to use my pcb design or 3D files. they are complicated and designed to fit scraps i had laying around.
The code is very friendly for beginners with explanation on editable values.
I linked the products I used (or similar).
I haven't tested it yet, waiting for car relay to arrive.XT30Screw terminalDC Power socket and JackArduino NanoPCB Socket
