Murex Welding Products has introduced air and water cooled welding packages featuring the Transmig 423S and 523S electronic microprocessor controlled heavy duty power sources. They are designed for fabrication and repair work in industries including, structural steelwork, turbine manufacture, offshore equipment, shipbuilding and hardfacing. MIG, MAG and Flux Cored Wire welding can be undertaken. The Transmig 423S and 523S are available for use with air-cooled MIG torches or as “W” versions, with in-built torch water-cooling units. Continuous voltage control from the wire feeder, full short circuit protection, interphase reactor and three levels of inductance provide optimum arc characteristics. In combination with either the Transmatic Lynx 4EHD wire feed unit, or when working as far as 70 metres away from the power source, with the Suitcase II wire feeder, welding performance up to 420A or even 520A at 60% duty according to model can be provided. With arc voltage being monitored at the torch, both can run with cable lengths up to 70m. Digital volt/amp metering is standard with a Last Reading Hold feature. To cover the full range of wire types and shielding gases that can be used, both power sources incorporate three inductance level settings. The Migpak 423S air cooled package consists of Transmig 423S, Transmatic Lynx 4EHD, MXA404 MIG Torch, 5m Interconnections, and a 3.5m work return lead. The water cooled package features a Water Adaptor kit, Water Hoses, and an MXW 454SC Torch. The Migpak 523S air and water cooled packaged have similar components.
