I built a spot welder that is powered by a car battery. The battery is 12V and 100amps. But unfortunately, it is a little bit too powerful, because it burns through the nickel strips and also through the battery really quickly most of the time.
So I would like to know what is the easiest way to reduce the power/voltage of the battery just a little bit? Will a voltage divider work in that instance? I added the picture of the spot welder.
