Welding diodes (boxed and unpackaged) are mainly used in resistance welding machines where high currents are required. A feature of the operation of diodes in welding machines is short-term cycles of passing current pulses, leading to the heating of the semiconductor structure, and then its further cooling, associated with restrictions on the time of continuous operation of welding machines ("heating – cooling" mode).
