PATON
®
PSI PRO 315 A 400 V DC MIG/MAG TIG/MMA
The distinctive feature of the welding units is the availability of a high-quality electrode wire feeding
unit and a KZ-2 euro type 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
other welding units with similar characteristics.
The basic advantages of the PATON
®
welding units are the following:
1.
The possibility to adjust welding parameters in wide ranges
a)
1 basic par 10 additional parameters for the manual arc welding process
(MMA)
b)
1 basic par 10 additional parameters for the argon arc welding process
(TIG)
c)
2 basic parameter + 8 additional parameters for the semiautomatic arc welding process
(MIG/MAG)
2.
The availability of the adjustable pulse welding mode for all the welding processes
3.
The welding unit is
protected against long-time fluctuations
of power supply voltage and
ensures welding arc stabilization when the input voltage of the unit changes in the range of
320 V through 440 V.
4.
The welding unit is rated for operation with a standard power supply system. Due to the higher
efficiency coefficient of the unit,
the power consumed by the unit is reduced by 50%
as
compared with other similar welding units.
5.
The rotation frequency of the driving motor of the ventilator of the welding unit can be
automatically varied depending on the temperature inside the unit
. This feature allows the
service life of the ventilator and driving motor to be increased and, additionally, dust content
inside the unit to be reduced.
6.
Comfortable use due to the long duty cycle at the rated current, which enables virtually
uninterrupted welding using electrodes Ф6 mm with the length of the welding wire 16 m (for PSI
315P) and 36 m (for PSI 400P)
7.
The enhanced reliability of the welding unit in operation in dusty environment
8.
The welding unit contains an electronic thermal protection system for protecting all the heat-
generating components of the welding unit against overheating.
9.
All the printed-circuit boards with electronic elements are
impregnated with two layers of high-
quality varnish
in order to provide the high reliability of the welding unit within its service life.
10.
Improved arc flash stability which in practice eliminates electrode adhesion.
11.
Easy replacement of fuses due to their location outside the device.
12.
When the source is separated from the wire feeder, it provides small dimensions and makes the
device mobile, which simplifies welding in hard-to-reach places.
