Resistance Spot Welding Controller with Constant Current feedback- Model WFB 777


  • Secondary Current Feedback for Constant Weld Current Output.
  • Eliminates Variation in weld output because of transformer losses.
  • Current feedback with the help of easy to mount toroidal current sensing coil.
  • Selection of constant current / constant voltage by user.
  • User selectable spot / seam mode.
  • Error detection for transformer over heat / thyristor over heat / pressure, water flow etc.
