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

Voltage up to 400V

Greegoo launched a new generation of welding diode. The new housingless welding diode is designed for medium frequency resistance welding and high current rectifier applications. The devices meet the market requirements for higher forward current, low conduction losses and higher power cycling capability. With this new design, the diodes focus on the best-in-class performance to lifetime ratio supporting a decrease of maintenance cycles. The main applications for the new diode generation are spot-welding in the automotive industry, low voltage electrolysis and surge protection.

The new welding diode generation offers the highest power cycling capability in the market. Compared to conventional devices the lower on-state voltage of the power diodes allows 10 to 15 percent higher currents. With this, the customer has the choice between a longer lifetime and an increased current for his application. With all the new features, the new power diode generation is ideal for extending the performance of existing designs with full mechanical compatibility.

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. Used by various industries, including resistance welding machine manufacturers, welding robotic service providers, and automobile manufacturers.
