ATTENTION!
When connecting the welding unit to the power distribution
board (at a temperature of 25 ºC), take into account through-the-wall wiring
and the lengths of extension cables.

GENERAL INFORMATION
The digitally controlled invertor-rectifier welding units
PATON
®
PSI 315Р / 400Р - 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.
The MIG welding units pertain to the Professional Series equipment and are designed for industrial
use. The operation of the welding unit is possible separately from an electrode wire feeding unit. This
operational mode is reasonable in order to provide the ease of use of the unit and compliance of the
unit with safety requirements. The additional adjustment operations provided for the welding unit
make it possible to set the optimal values of the operating parameters of the unit in various operating
modes characterized by a high load factor at a rated current of up to 315 A or 400 A. The welding units
can be used for manual arc welding with standard electrodes 1.6 … 6 mm in diameter and free-melting
electrodes up to 6.0 mm in diameter and for semiautomatic arc welding with solid electrode wire 0.6
… 1.6 mm in diameter. The function of reduction of open-circuit voltage in the manual arc welding
process (MMA), with the possibility for this function to be switched on and off, allows the welding
unit to be operated in unsafe environment.
