KE type thyristor for welding machineDetailed product description：

The thyristors used in KE type welding machines have the characteristics of low on state voltage drop, high dynamic current rise rate, and strong ability to withstand frequent short circuits. The structure comes in bolt type (spiral type) and flat plate type, and the radiator is matched with a level. There are various types of air cooling, which can be used for various welding machines.
Thyristors used in welding machines are specialized thyristors designed for various types of welding machines, and can be widely used for automatic control in various resistance welding machines and arc welding machines.
