The MM are three-phase electromechanical generators for seam welding (MIG/MAG) with separate electronically controlled wire feeder.
WHAT SETS IT APART
These are extremely strong, reliable and easy to use welders. They are idea for light, medium and heavy metal work, depending on the model. All the magnetic coils are made from the best quality copper and cooled by forced ventilation. This gives excellent performance with a 60% work cycle. A temperature probe protects the internal components. The voltage change terminal block inside the machine permits changing the supply voltage. The progressive position change, 21 positions for the MM 282-322 and 28 positions for the MM 382-452, permits a wide range of setting parameters for welding. The wire feeder with 2-roller TM2 or 4-roller TM4 gives smooth and constant rod flow, thanks to the control board and the 50W and 100W motors installed. On request they may be fitted with digital volt/ammeter. On request, a CW5 gun-cooling unit may be installed. The connection extensions between the machine and wire feeder are available in standard lengths of 4, 10, 15 and 25 m. air or water. Special measurements are available on request.
