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