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.
