GENERAL PROVISIONS
Digital inverter semi-automatic machines PATON ProMIG-200/250/250-400V are designed for manual metal
arc welding (MMA), tungsten arc inert gas welding (TIG) and semiautomatic metal inert/active gas welding
(MIG/MAG) in the atmosphere of shielding gas with direct current. Advantageous completely digital control
implemented in the design of the machine provides freedom from limitations typical for multi-functional systems
based on analogous control system, which are always inherently geared towards a specific mode, while other modes
are additional and have drawbacks in terms of control. On the contrary, control board of a completely digital system
offers all capabilities of the source within the range of its full power, regardless of the mode of use. This Professional
series is designed for industrial use. The source can be separated from the wire-feeding machine both for
convenience and safety practices. What is more, additional adjustments allow setting the inverter rectifier to
optimum settings in different situations.
They provide virtually uninterruptible load duration at full fair rated current
of 200 A and 250 A respectively, which is sufficient for work with any electrodes from
Ф
1.6 mm in diameter up to
low-melting
Ф
6 mm electrodes, as well as for semiautomatic solid wire welding featuring wire from Ф0.6 mm to
Ф
1.2 mm in diameter. Initially, the source is set to settings, which are optimum for most applications, and is quite
easy to use if you do not go into additional details of settings, which require good welder's skills. For safety in
dangerous working conditions, the rectifier is equipped with an in-built unit for open-circuit voltage reduction in
MMA mode, which can be enabled or disabled. The distinctive feature of PATON semi-automatic machines is very
robust, high-quality and structurally sound wire feeding mechanism, as well as availability of KZ-2 slot of world
standard EURO type, which allows user changing torches at his/her own discretion.
This ProMIG model by PATON is equipped with a unit for overvoltage, as well as undervoltage,
protection.
Due to increased frequency of voltage supplied to the transformer, the transformer can be made several
tenfolds smaller. That is why weight and overall dimensions of this machine is several times smaller than
those of regular equipment with identical output parameters.
Main advantages:
1. Wide range of welding parameters adjustment:
a) in MMA mode
–
1 (main) + 10 (additional)
b) in TIG mode
–
1 (main) + 8 (additional)
b) in semiautomatic MIG/MAG mode
–
2 (main) + 4 (additional)
2. Adjustable pulsed welding mode for all welding types.
3. In addition to voltage surge protection, the machine is equipped with a stabilization system for
large
long-term
voltage variations in the 160 V to 260 V single-phase supply mains. However, it must be kept
in mind that minimum voltage of 160 V allows for welding with an electrode not more than
Ф
3 mm in
diameter or semiautomatic welding with wire up to
Ф
0.8 in diameter.
4. The machine fits standard domestic power mains. Due to high efficiency factor, the source provides
twice
lower power consumption
compared to regular sources.
5. Adaptive fan speed
–
i.e. increases when the machine heats up and slows down when it is cold, thus
prolonging service life of the fan and reducing amount of dust accumulated in the machine.
6. Convenient use due to high load duration (LD) at
rated current
, which enables virtually
uninterruptible
welding electrodes at rated current, at a temperature of 25 °С.
7. Increased machine reliability in dusty production environment, microelectronic circuitry of the source is
located in a separate compartment.
8. All heating elements of the source are provided with an
electronic heat protection system.
9. All electronic parts of the machine are impregnated with
two layers
of high-quality varnish, which ensures
product reliability during the entire service life.
10. Enhanced arcing stability.
