US-based Magnatech has introduced the Pipemaster, used for multipass orbital pipe and boiler tube welding. The Pipemaster has an autoranging input of 220 to 480VAC and a 200amp output, and will operate weld Head models incorporating controls for torch rotation, wire feed, torch oscillation, and arc voltage control functions. The new Autoprogramming mode allows operation without programming training. An inexperienced user enters pipe OD, wall thickness, and material. A weld program will automatically be generated. The new weld program can be run, and if not perfect, can be modified in two ways. Using Edit mode, any parameter can be changed at any point during the weld. Using Scaling mode, certain parameters (such as rotation spread, or amperage) can be changed by a percentage for the entire program. The power source stores up to 100 weld programs.
