Description
We are the official distributor and authorized service provider of the GYS brand in Poland.
GYS MULTIWELD 400T is an extremely powerful, three-phase (400V) inverter multiprocess welder designed for the most intensive MIG/MAG, MMA (shielded electrode) and TIG Lift welding. It is a top-performance machine, designed for professional industrial applications, heavy welding work and prolonged duty cycles in the toughest conditions.
The welder offers an impressive maximum welding current of 400 amperes (for MIG/MAG) and features an advanced, intuitive control panel with precise adjustment of all parameters. In MIG/MAG mode, it has extensive adjustment of welding voltage, wire feed speed and an advanced synergy function with numerous programs for different materials, gases and thicknesses. In MMA mode, it offers adjustable Hot Start, Arclace and Anti-Sticking, and advanced Pulse MMA with full adjustment. TIG Lift mode allows direct current (DC) welding with friction ignition. The MULTIWELD 400T can weld carbon steel, stainless steel and minium (MIG/MAG and TIG – requires a suitable TIG holder and shielding gas). It is equipped with a 4-roller wire feeder for reliable and stable feeding even with maximum loads and long handles.
The version “WITH” means that the kit includes the basic professional accessories necessary to start welding by various methods. The “T” designation in the name indicates a three-phase power supply.
