he MIG·O·MAT-appliances plasmaJET 50 is especially designed for microplasma-arc welding. The MIG·O·MAT plasmaJET 50 has a maximum current of 50 A in case of a duty cycle of 100 %. The unit is equipped with an easy, well-arranged micro control device especially suitable for the requirements of a manual welding process. This control device allows the functions welding in 2-cycles and 4-cycles, plasma spot welding, infinitely variable pre-selection of the main and pilot-arc current as well as a pulse-mode operation with adjustable parameters. The control device is equipped with a digital display of the welding current and the pilot-arc current and is prepared for the utilization of a foot control pedal and plasma spot welding control device.
