Welding Diodes

Welding diode is a high current low voltage semiconductor device used on medium frequency spot welding machine, MFDC spot welder, seam welder. It's current range are from 7100A to 13500A, voltage range is 200V or 400V.

Feature:

Designed for medium frequency welding equipment, spot welding device

High reliability in welding machine

Very low on-state voltage

Very low thermal resistance

Up to 2000HZ

Application

For all kinds of intermediate frequency, power frequency resistance welding machine. Such as automobile welding clamp, seam welding machine, mesh welding machine and so on.
