Welder MIG/MAG MMA/TIG Lift Paton StandardMIG-270 400V

Basic data of the Paton StandardMIG-270 400V welder

The PATON StandardMIG 270 400V Digital Inverter Welder is intended for semi-automatic MIG/MAG arc welding, gas shielded TIG arc welding and manual MMA arc welding with direct current (DC) with the possibility of using the PULSE function.


The “Standard” series is dedicated to domestic and semi-industrial use. PATON PSI 270 Standard ensures 55% duty cycle at full rated current of 270A without any loss of efficiency and quality of work. It is also worth mentioning that the welder achieves a 100% duty cycle at 180A. The robust design and simplicity of operation makes the machine easy to use – easy settings result in excellent weld quality. The use of the fully electronic control method in this series excludes the disadvantages which are characteristic of multifunctional systems. The welding source is set to optimal values, which allows you to start working with it right away, even if you are a beginner. For more advanced work, the device is equipped with additional functions. A characteristic feature of PATON™ Standard series semi-automatic machines is a high-quality wire feeder, which has been additionally sealed, as well as the existing KZ-2 “EURO” type integrated connector, which has become a standard all over the world, allowing the user to choose any MIG/MAG torch according to his/her preferences.

All PATON MIG/MAG welding machines are adapted for welding with self-shielded wire. Such welding, as opposed to the traditional MIG/MAG welding process, is performed without the use of shielding gas – however, it requires the use of a special welding wire. The wire produces its own shielding which helps to protect the welding arc. Self-shielded wire suitable for PATON welding machines can be purchased here – 5kg spools of wire will fit all wire feeders.



Paton MIG/MAG welders of the Standard and PRO series have the possibility of brazing thanks to the function of changing the inductance in three steps. The inductance control allows the arc characteristics to be optimised according to the thickness of the component to be welded. This function is necessary to change the speed of the current flow when changing the arc voltage. The thinner the component to be welded using MIG/MAG, the higher the inductance should be (soft arc – less fusion), for thicker components the opposite (hard arc – more fusion).



– PULSE in TIG welding – full control of heat entering the material – a great feature for welding stainless steel and acid-resistant steel,

– PULSE in MMA – easier transfer of material from electrode to weld pool, better quality of welded joint,

– Pulses in MIG/MAG welding – easier detachment of metal droplets from the end of electrode wire, possibility to adjust pulse current parameters. MIG welding with pulse is useful for welding stainless steel, acid-resistant steel and aluminium alloys. In addition, pulse welding provides better parameters for soldering CuSi3



Unlike the rest of the Standard Series, the PATON PSI 270 400V welder has a 55% duty cycle at its rated current of 270A. In addition, the wire feeder built into the welder allows a large 15kg spool of wire to be fitted – unlike the other STN series units which only handle spools of up to 5kg.

Compared to inverter welders from other manufacturers, this product was invented by the designers of the Pilot Plant of Welding Equipment of the Electric Welding Institute named after E. O. Paton, has the following advantages:

  • Wide range of adjustment options for welding parameters:
    – the MMA method – 1 (basic) + 10 (additional)
    – the TIG method – 1 (basic) + 4 (additional)
    – the MIG/MAG method – 2 (basic) + 4 (additional)
  • Pulsed welding function, which is programmable in all welding modes.
  • Protection system against voltage surges.
  • Despite the protection against voltage spikes, a stabilisation system has been installed for larger long-term voltage differences in the single-phase power supply from 160 V to 260 V. It is worth remembering that in the case of the minimum voltage of 160 V, welding with an electrode with a diameter of no more than Ф3 mm or semi-automatic wire welding with a diameter of no more than Ф 0.8 mm may be performed.
  • Adapted to the standard power grid. Thanks to its high efficiency, the source provides twice as much electricity demand as traditional sources.
  • The adaptive fan speed, which increases at the start of welding, increases even more when the welder is warmed up and decreases when it is cool, saves fan wear and reduces the amount of dust in the welder.
  • Convenience of operation due to the long load time at the nominal current, which allows welding practically without interruption with Ф5 mm electrodes (for PSI 250 Standard), e.g. АNО-/21/36 at 200 А current at 25 °С.
  • Increased reliability of the welder in dusty and wet production conditions. The microelectronic system has been moved to a separate chamber protected by a robust construction.
  • All electronic components of the welding machine are impregnated with two layers of high-quality lacquer, which ensures the reliability of the product during its lifetime.
  • The welding machine is equipped with an electronic thermal protection system which protects all heat-generating elements of the welding unit against overheating.
  • Improved stability of the electric arc glow.
  • Continuously adjustable welding parameters.
  • Reliability thanks to the use of the latest advanced IGBT technology.
