MF 70 - 90 - 130 - 160
PPN Inverter spot welders
Suitable for both spot and projection welding , BSW and
MF models fully meet the mass production toughest industrial applications.
Thanks to their features, they represent the ideal solution for resistance
spot welding of Aluminum and other material not easily weldable by
conventional resistance equipment. Equipped with microprocessor control,
concomitant safety side buttons and solenoid valve, upon request, they can
be supplied with special controls and configurations.
MF range of
medium-frequency inverter (1000 Hz) resistance welders is the ultimate
answer to increasing demand for quality in resistance welding
applications. Main advantages versus traditional equipment are: fast
millisecond current regulation, constant current control, high quality and
perfect control of the energy transferred to the weld nugget.

TECHNICAL ADVANTAGES |
DIRECT CURRENT
- High quality joints
- Large power for projection welding
- Large power for welding with increased arm lengths
- The presence of magnetic materials between the arms does not affect the
welding
- Long electrode life
- Highest efficiency
- Reduced welding time |
THREE PHASE MAINS SUPPLY
- Balanced power absorption on the three mains phases
- Low primary consumption
- Lower cost for electric power
- High power factor and output |
- Welding tasks previously solved by capacity
discharge welding (C) are now possible by MF range in a more economic way.
- Quick upsloping to the preset welding current |
Monitoring of the welding process every 1
millisecond (1000 Hz) versus traditional 20 millisecond (50 Hz). |
Less thermal loss through the workpiece and
electrodes. |
