The digitally controlled inverter-rectifier welding unit TIG-200S of the STANDARD series is designed for direct-current gas-shielded welding according to such welding processes as a manual arc welding process (MMA), argon-arc welding process (TIG), and semi-automatic arc welding process (MIG/MAG). The welding units of the Standard series are designed for exacting users requiring a compact welding unit and an optimal ratio between the portability and functional characteristics of a welding unit with a rated current of up to 200 A. The welding unit can be used for manual arc welding with electrodes 1.6 … 5.0 mm in diameter and for semi-automatic arc welding with solid welding wire 0.6 … 1.0 mm in diameter.
The welding unit contains a built-in module for contactless arc starting. The welding unit can be adjusted in order to set the optimal unit parameter values in various operation modes.
The welding unit contains a module for protecting electronic elements against power supply overvoltage and undervoltage.
