1. GENERAL
PATON PRO-160/200/250/270-400V/350-400V/500-400V/630-400V digital inverter rectifiers are
designed for direct-current manual metal arc (MMA) welding, tungsten-arc inert-gas (TIG) welding
and metal-arc inert-gas welding/metal active gas welding (MIG/MAG) (where inert gases and gas
mixtures serve as a source together with an external wire feeder). The advantages of using a fully
digital control method in this unit are that there are no disadvantages inherent in multifunctional
systems made based on analogue control systems, which by definition are always configured for a
specific mode, and all other modes, as additional ones, have control disadvantages. However, in a
fully digital system, the control board has absolutely all the assets of the source, within its full power,
and the mode of use does not make any difference. The
“ Professional ” series is designed for industrial
use; with additional adjustments, the inverter rectifier can be adjusted to the most optimal settings in
various situations. The units provide virtually continuous load duration at full true rated current of
160A, 200A, 250A, 270A, 350A, 500A, 630A, respectively, which is enough for working with any
elec
trodes from Ø1.6mm up to Ø8mm (for PRO -630-400V) and semi-automatic welding with solid
wire with a diameter from Ø0.6mm to Ø2.0mm (for PRO -630-400V). The source is initially set to
optimal values for most applications, and is quite simple, unless the extensive expertise of the welder
enables the use of fine-tuned settings. For dangerous operating conditions, a no-load voltage
reduction unit is integrated in the MMA mode, with the possibility of switching it on and off.
This PATON PRO model has a built-in under-voltage protection unit.
The device stores under its number in each welding mode up to 16 users
’ settings (programs).
The device saves in memory all the current settings at the moment of switching off and restores them
at the time of switching on.
Main advantages:
1. Wide range of welding parameters adjustment options:
a) in the MMA mode - 1 (main) + 7 (optional) + 3 (for pulse mode)
b) in the TIG mode - 1 (main) + 1 (optional) + 3 (for pulse mode)
c) in the MIG/MAG mode -
1 (main) + 3 (optional) + 3 (for pulse mode)
2. Very wide range of pulse mode settings for all types of welding;
3. In addition to protection against under-voltage, a stabilization system is installed for operation with
significant long-term drops in line-to-line voltage from 160V to 260V (for models PRO-
160/200/250) and from 320V to 440V (for models PRO-270-400V/ 350-400V/500-400V/630-400V).
4. The unit is adapted to a weak power supply. Due to its high efficiency, the source provides half the
power consumption compared to conventional sources;
5. Adaptive fan speed, i.e. it increases at the start of welding, increases, even more, when the unit is
heated, and slows down when it is cold; this saves the fan life and reduces the amount of dust in the
unit;
6. Convenient operation due to the large load duration (LD) at rated current, which allows welding
continuously with electrodes;
7. Increased reliability of the unit in dusty production conditions; microelectronics of the source is
housed in a separate compartment;
8. All heating elements of the source are equipped with a thermal electronic protection system;
9. All unit ’ s electronics are covered with two layers of high-quality varnish, which ensures the
reliability of the product throughout its entire service life;
10. Improved excitation and arc stability, which virtually eliminates electrode sticking.
11. Small dimensions and weight of the unit do not affect its technical qualities, which simplifies
welding in hard-to-reach places.
