MF 1040 - MF 1041 - MF 5020 - Vertical Stroke Spot/Projection Welder - DC - Medium Frequency Inverter

RWMA Member
  • Overview

    The most enhanced inverter technology for medium frequency spot-welding available for everyone. These equipment – fitted with new inverters with WSI 100 and FILIUS COMPACT controls – represent a valid solution for anybody looking for all Medium Frequency benefits in both spot-welding applications and nut projection welding too. MF 1040 and 1041 models allow to monitor the whole welding process every 1 ms (1000 Hz). The far faster MF 5020’s, whose inverter operates at 5000 Hz,are able to even control the process every 0.2 ms.


    The MF Inverter spot welders suitable for both spot and projection welding, fully meet the mass production toughest industrial applications. Thanks to their features, they are particularly suitable for welding very thin thickness, metals hardly weldable such as copper, brass, aluminum alloys or zinc coated steels, etc., also whenever different metals are to be joined.


    Main advantages versus traditional 50 Hz equipment are: fast millisecond current regulation, constant current control, high quality, symmetrical mains load and perfect control of the energy transferred to the weld nugget.

  • Features

    Direct Current

    • High quality joints
    • No welding power losses 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


    MF Medium-Frequency

    • Monitoring of the welding process every 1 millisecond (1000 Hz)  / 0.2 milliseconds (5000 Hz) versus traditional 20 millisecond (50 Hz).
    • Shorter welding times and lower welding current, by saving approx 30% mains consumption
    • Quick upsloping to the preset welding current
    • Less thermal loss through the workpiece and electrodes
    • Less imprint and deformation


    WSI 100 Control Panel

    WSI 100 control panel, in addition to the traditional adjustments, allows the operator to control the welding process in different modes: direct current and imposed limits.


    Other properties of WSI 100 control are the ability to manage up to 64 welding programs and graphically view the current and welding time.
