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.
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.
