Resistance welding machines Controller

Description

The intelligent SEJ-MFDC DIT series inverters have been specifically designed for spot, projection and resistance seam welding. The extensive control functions guarantee high process reliability. The SEJ-MFDC DIT family offers a variety of additional functions for welding high-strength metals, aluminum and three-member joints.

The 1,**0 Hz medium frequency/DC technology has proved its particular economic efficiency in many applications in contrast to other processes:

Higher welding quality via more dynamic current control than for the AC system

Weldability of many materials increased by more intensive energy supply

Spatter reduced by decreased welding current and/or current time

Electrode life lengthened thanks to lower thermal and mechanical load on the electrode caps

Smaller and lighter transformers for integration in the electrode holders
