MF Series Middle Frequency Direct Current Invert Technical System can be used for Spot welding machine,projection welding machine,butt welding machine,and so.

The Spot Welding Machine with this Middle Frequency Direct Current Invert Technical System is mainly used for welding the aluminium or copper material with very good welding quality and welding result.

Main Features:

1. Light weight transformer for using in industrial Robots and hanging welding gun.

2. Very low inductive loss large DC welding current.

3. Attain target current quicker

4. More accurate current control, more responsive

Current control.

5. Symmetric mains loading with high power factor.

6. Better for welding galvanized sheet, non-ferrous

Metals and different materials.

7. High quality in welding, compactness and lightness as well as power saving.
