1. GENERAL INFORMATION
The digitally controlled rectifier welding units
PATON
®
VDI 160P, VDI 200P,
and
VDI 250P-230V
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)
(with the welding unit operating together with an
external electrode wire feeding unit). 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 MMA 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 MMA welding units pertain to the
Professional
Series equipment and are designed for
industrial use. 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 160 A, 200 A, or 250 A. The welding
units can be used for manual arc welding with standard electrodes 1.6 … 5 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 … 1.2 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.
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 4 additional parameters for the argon arc welding process (TIG)
c)
1 basic parameter + 5 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
160 V through 260 V. It should be noted that welding at a minimum voltage of 160 V is
allowed only by using an electrode not more than 3 mm in diameter for the manual arc
welding process, or electrode wire not more than 0.8 mm in diameter for the semiautomatic
arc welding process.
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
percent
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.
Convenience of work due to high efficiency of the device at the rated current, which allows
for quality welding with electrodes Ф4mm (VDI 160 PRO), Ф5mm (VDI 200 PRO) and
Ф6mm (VDI 250 PRO), eg ANO-21, ANO-36.
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. Improved arc stability
