PSI-250S(5-2) DC MMA/TIG/MIG/MAG

The digitally-controlled one-body inverter-rectifier semi-automatic welding units MIG/MAG of the STANDARD series are 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 units are intended for residential and subcommercial use. The welding units are rated for operation with an optimal operating load factor at rated currents 150 A, 200 A, and 250 A, correspondingly, in operation from a 220 V single-phase power supply system or a 380 V three-phase power supply system. These currents are sufficient for welding with any electrodes in the range from electrodes 1.6 mm in diameter through low-melting electrodes 6.0 mm in diameter (for MIG/MAG- 250S), and for semi-automatic arc welding with solid welding wire 0.6 … 1.2 mm in diameter (for MIG/MAG-250S).

ALL CHARACTERISTICS:

CHARACTERISTIC FEATURES AND ADVANTAGES
  • The possibility to control welding parameters in a wide range:
    • In the ММА process: 1 basic parameter + 10 additional parameters
    • In the TIG process: 1 basic parameter + 4 additional parameters
    • In the MIG/MAG process : 2 basic parameters + 4 additional parameters
  • The availability of the adjustable pulse welding mode for all the welding processes.
  • The microelectronic elements of the unit are installed in a special compartment.

The parameters of the welding unit are preset as optimal for the most operation modes. The more complex adjustment is possible, if required, provided that the welder has corresponding knowledge and experience. The characteristic feature of the semi-automatic welding units of the STANDARD series is that every unit contains a high-power, reliable, and airtight welding wire feeding unit.
