1. GENERAL INFORMATION
The digitally controlled invertor-rectifier welding units
PATON
®
ADI 160S DC oraz ADI 200S
DC
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 TIG 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 TIG welding units pertain to the “
Standard”
Series equipment and are designed for
users requiring a compact welding unit and an optimal ratio between the portability and functional
characteristics of a welding unit with a rated current of up to 160 A or 200 A. The welding units can
be used for manual arc welding with electrodes 1.6 … 5.0 mm in diameter and for semiautomatic
arc welding with solid electrode wire 0.6 … 1.0 mm in diameter. Each of the welding units contains
a
module for contactless arc starting
. 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. 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 parameter + 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)
1 basic par 4 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 contains a module for
contactless arc starting.
4.
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.
5.
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.
6.
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.
7.
The welding unit is easy operated due to the optimal operating load factor in operation at the
rated current.
8.
The enhanced reliability of the welding unit in operation in dusty environment
