Therefore, as the thickness of the plate increases, the current needs to be increased. The way to increase the current is generally to adjust the voltage. (In the case of a certain resistance, the higher the voltage, the larger the current), or the current is constant. The power-on time can also increase the heat input to obtain a good welding effect;
Spot welding is generally divided into hard specifications and soft specifications. The hard specification is high current + short time, and the soft specification is small current + long time.
