Spot welding temperature is too high to deal with
It's pedal like. But the water pipe is also connected. However, the solder joint temperature is still very high. I also adjust the temperature control of the controller, but still the same as usual, welding contact points are black, welding surface also appeared a lot of holes, how should I deal with it?
It can be cooled by running water. A small pump and some pipes can solve the problem
