GENERAL INFORMATION
The digitally controlled invertor-rectifier welding units
PATON
®
PSI-160S / 200S / 250S /
250S-400V
are designed for direct-current gas-shielded welding according to such welding processes as a
manual arc welding process
(MMA)
, an argon arc welding process
(TIG),
and a semiautomatic arc
welding process
(MIG/MAG)
. The digital controller used in these welding units ensures significant
advantages for the welding unit as compared with multifunctional analog controllers, as the analog
controllers are designed for the specific operating modes of controlled equipment and are not optimal in
all operating modes. The digital controller of the MIG welding units allows all the capabilities of the
welding unit, up to its capabilities at full power, to be used in all the operating modes of the unit.
This welding unit is designed for household and semi-industrial use. It provides a good load duration at
full rated current of 200A and 250A, respectively, when powered by a powerful single-phase 220V,
which is enough for any electrodes 1,6 … 6 mm to free-melting electrodes 6 mm (for
PSI-250S
) and
semi-automatic welding with solid electrode wire 0.6 … 1.2 mm in diameter (for PSI-250S). The power
source is initially set to the optimum values and is simple enough for most applications if you do not go
deeply into setting that require great welder skills. It is possible to replace the polarity for welding flux
electrode wire. For dangerous work environment, there is built unit to reduce the open circuit voltage in
the
MMA
mode, with the ability to turn it off and on. The distinctive feature of the welding units is the
availability of a high-quality electrode wire feeding unit and a KZ-2-euro style connector, which allows
the operator to replace welding torches at his option.
The welding unit contains a module for protection against excess and low power supply voltage.
Due to the increased frequency of the input voltage of the rectifier transformer of the welding unit, the
weight and overall dimensions of the transformer are significantly reduced as compared with classic
welding units with similar characteristics.
