The Weldforce range of modular MIG/MAG/MMA welding machines is specifically designed to provide welding power, arc control and durability in heavy industries such as shipbuilding, offshore fabrications, the rail industry and other large to medium sized fabrication shops as well as out on site. This range is for users who have a requirement using either efficient basic MIG welding or more advanced synergic MIG welding. A feature of this new range is the wire feed units, which are made of a double skinned PE-nylon material, making them light weight, yet very tough, durable and resistant to weld spatter and grinding sparks as well as having the capability to operate in ambient temperatures up to 120 degrees Celsius. Weldforce comes as either an air cooled or water cooled version, comprising three different power sources and four wire feed units enabling the operator to select the package most suited to his/her own requirements. The KPS3500, KPS4500 and KPS5500 power sources provide 350A at 80% duty cycle, 450A at 60% duty cycle and 550A at 60% duty cycle, respectively, and all having a 65V open circuit voltage (OCV) from a three-phase 50/60Hz 230 or 400V power supply. In addition, the Synergic versions KWF 200 and KWF 300 provide the operator with the facility of advanced Synergic MIG welding and memory functions to obtain the optimum welding properties. There are 46 Synergic MIG welding programs using a one knob control – 19 for mild steel, 21 for stainless steel, four for aluminium and two for other special materials as well as parameter memory functions and MMA welding.
