MF Inverter spot welders, suitable for both spot and projection welding, fully meet the demands of the toughest industrial mass-production applications. Their characteristics make them particularly suitable for welding very thin, difficult-to-weld metals such as copper, brass, aluminium alloys and zinc-coated steels, as well as for joining dissimilar metals.
Compared with conventional 50 Hz machines, the main advantages are: rapid millisecond current regulation, constant current control, high quality, balanced mains loading and precise control of the energy transferred by the weld nugget.
DIRECT CURRENT
- High-quality joints
- No loss of welding power as arm length increases
- The presence of magnetic materials between the arms does not affect welding
- Long electrode life
- Maximum efficiency
- Reduced welding time
MF medium frequency
- Welding process monitoring every 1 millisecond (1000 Hz) / 0.2 milliseconds (5000 Hz), compared with the conventional 20 milliseconds (50 Hz).
- Shorter welding times and lower welding current, with approximately 30% less mains power consumption
- Rapid rise to the preset welding current
- Less heat loss through the workpiece and electrodes
- Fewer indentations and less distortion
- WSI 100 control panel
In addition to conventional settings, the WSI 100 control panel allows the operator to control the welding process in various modes: direct current and preset limits.
Additional features of the WSI 100 controller include the ability to manage up to 64 welding programmes and a graphical display of current and welding time.
