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 par 3 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.
