MGT200 is the newest multipurpose power source, with built-in wire feeder, for MIG/MAG welding (of steel, stainless steel and aluminium), TIG welding with HF or LIFT ARC start, and MMA welding The inverter technology and the special design features have contributed to the reduction in weight and size, as well as in absorbed power, without penalizing their reliability and performance. The welding process, controlled by the microprocessor thousands of times per second, ensures stable and almost spatter-free welding, exceptional dynamics (even at low amperage), and perfect arc start. The fully digital control board, equipped with a wide LCD display, facilitates the selection of the type of welding process. The simple and accurate setting, as well as the continuous detection of the welding parameters, assures process quality and reproducibility. In MIG/MAG SYNCH welding operation, the parameters are simply set by selecting the wire type and diameter, and the gas to be used. In order to suit the different users’ needs, all parameters can be set and modified manually, as well. TIG welding operation allows adjustment of slope-up, slope-down, pre-gas and post-gas between 0 and 10 seconds. The PULSED TIG option, offering adjustable pulse frequency between 1 and 250 Hz, as well as adjustable base and peak current, allows welding on very thin plates as the limited heat produced reduces the risk of deformation of the welded metal. MMA welding operation allows adjustment of both Hot Start, to facilitate arc start when welding with coated electrodes, and Arc Force, to prevent these from sticking when welding. The power sources are equipped with appropriate safety devices to ensure their performance. A temperature sensor and the mains voltage control (fluctuations between -20% and +15% of the nominal value) protect the internal components. Versions available are the air-cooling-on-trolley and the water-cooled version (with built-in torch cooling unit).
