MF-System - PSI 6000

Content

The intelligent PSI 6000 inverters have been specifically designed for spot, projection and resistance seam welding. The extensive control functions guarantee high process reliability. The PSI family offers a variety of additional functions for welding high-strength metals, aluminum and three-member joints.

The 1,000 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
