1. GENERAL
PATON ProMIG-160/200/250/270-400V/350-400V/500/630 digital semi-automatic inverter units are
intended for direct current metal-arc inert-gas welding/metal active gas welding (MIG/MAG), as well as for
tungsten-arc inert-gas (TIG) welding and manual metal arc (MMA) welding. 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. The source can be separated from the wire feeder both for ease of operation
and for safety, and through additional adjustments, the inverter rectifier can be adjusted to the most optimal
settings in various applications. The units provide virtually continuous load duration at full true rated currents of
200, 250, 270, 350, 500 and 630 amperes, respectively, which is enough to work with any electrodes from Ø1.6mm
up to the most refractory ones, of Ø8mm (for ProMIG
-630) and semi-automatic welding with solid wire with a
diameter from Ø0.6mm to Ø2.0mm (for ProMIG -630). 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 additional 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. A distinctive feature of PATON semi-automatic units is a very
powerful, high-quality and air-tight wire feeder made of metal. Also, the availability of the EURO-type KZ-2
connector, which has become a global standard, allowing the user to subsequently change the torches as seems fit.
In models with the "-15-2" prefix, a 2-roller feeder is installed, and with the "-15-4" prefix, a top-quality
4-roller feeder with a drive to all rollers is installed.
All PATON ProMIG models have an integrated under-voltage protection unit.
By increasing the frequency of the applied voltage to the transformer, it became possible to reduce it tenfold. That
is why the unit has several times less weight and overall dimensions with the same output parameters, in
comparison with the conventional equipment.
The unit saves all current settings at the time 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) + 7 (optional) + 3 (for pulse mode)
c) in the MIG/MAG mode
– 2 (main) + 6 (optional) + 3 (for pulse mode)
2. An adjustable pulse mode is available in 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 ProMIG-200/250 models) and from 320V to 440V (for
ProMIG-270/350/500/630 models).
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 when the unit heats up 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 almost
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 impregnated 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. High mobility due to modular design, as well as small dimensions and weight of the unit without loss of technical
qualities, simplifies welding in hard-to-reach places.
