Resistance welding

MF

RESISTANCE MEDIUM FREQUENCY THREE PHASE

SPOT/PROJECTION WELDERS

The MF range of medium-frequency inverter resistance welders is the ultimate answer to increasing demand for quality in resistance welding applications.
Constant current control, fast millisecond current regulation, high quality and perfect control of the energy transferred to the weld nugget are the main advantages versus traditional 50 Hz equipment.
MF models fully meet the toughest mass production industrial applications. Thanks to their features, they represent the ideal solution for resistance spot welding of thin thickness and of hardly weldable material, such as copper, brass, aluminium alloys, zinc plated and other coated steel.

MF – the latest inverter solution

MF represent a valid solution for anybody looking for all Medium Frequency benefits in spot and nut projection welder. MF models allow to monitor the whole welding process every 1 ms (1000 Hz).

The MF Inverter fully meets the mass production necessity. Thanks to their features, they are suitable for welding very thin thickness, metals hardly weldable such as copper, brass, aluminium alloys or zinc coated steels, etc., also whenever different metals have to be joined.

MF 1040 – MF 1041 – MF 100 – MF 160 – MF 200

MF Inverter spot welders can be standard supplied in different sizes. Thanks to this wide range of solution it is possible to find the right solution at any necessity no metter how complicate is the task required.

Other characteristics

All MF equipment can be converted into bench version types (BSW) or utilized in seam-welding applications too
Direct current welding
Large power for welding with increased arm lengths
Magnetic materials between the arms does not affect welding
Self-lubricated pneumatic components
Water cooled secondary circuit
Low tendency for welding spatters
Less imprint and deformation
Very long electrode life
