What Is Welding Diode

What Is Welding Diode?

 

Welding diode is a high current low voltage semiconductor device.Its current range are from 7100A to 13500A.Voltage is 200V or 400V.Welding diodes also are known as “Welder Diodes”,”Welder Rectifier Diodes”.Welding diodes are the core rectifier components during resistance welder.
