Welder Inverter Paton MultiPRO-270 (15-4) MIG/MAG MMA/TIG HF 400V – basic data

The digital multifunctional welder inverter PATON MultiPRO 270 15-4 400V is intended for semi-automatic welding with the MIG/MAG method, manual arc welding with the MMA method, and arc welding with the TIG HF method in a shield of gases and protective mixtures with direct current. The MultiPro series is equipped with a non-contact arc ignition module (oscillator) with a built-in gas supply valve.

The advantage of using a fully electronic control system in this device excludes the disadvantages which are characteristic of multifunction devices based on analogue control systems which, by definition, are always directed towards one specific method and all other methods have control disadvantages as an additional feature. In a completely electronic system, the control system has absolutely all the resources of the source, within the limits of its full power and regardless of which method is used. The “Multi-Professional” series device is designed for industrial use, the source can be separated from the welding wire feeding mechanism for convenience as well as safety.


Thanks to the possibility of additional adjustment, you can choose the most optimal welding machine setting according to the situation. The source provides a nominal current of 270А, which is sufficient for work with electrodes from Ф1.6 mm up to easily fusible Ф6 mm and semi-automatic welding with solid wire with a diameter of Ф0.6 mm to Ф1.2 mm. The source defaults to optimal values and is simple enough if you don’t go into the details of the settings, which already require more experience from the welder. For hazardous work conditions, a block for lowering the idle voltage in the MMA method is built in, with the possibility of turning it on and off.


A characteristic feature of PATON® semi-automatic machines of the “Multi-Professional” series is the high-quality, sealed, metallic wire feeder, as well as the existing KZ-2 “EURO” type connector, which has become a standard in the world, allowing the user to change the holder at will in the future. The device has a protection module against abnormal levels of supply voltage (overvoltage or voltage drops) as well as against surges. Due to the increased frequency of the voltage supplied to the transformer, the transformer can be several times smaller. Therefore, the weight and overall dimensions of the welder are several times smaller than those of ordinary devices with identical output parameters.


Functions and features of the Paton MultiPRO 270 (15-4) MIG/MAG MMA/TIG HF 400V welder inverter

All PATON MIG/MAG welding machines are adapted for welding with self-source wire. Such welding, as opposed to the traditional MIG/MAG welding process, is performed without the use of shielding gas – however, this 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 – 5 kg spools of wire will fit all wire feeders.



The MultiPro series welders have a built-in HF IONIZER, which enables contactless arc ignition in TIG welding. This extension is a function of the TIG handle control button. The handle button control cable connects directly to this module. When the control button on the torch is pressed, the control signal is sent to the welding machine controller, which develops the function of the previous t1 gas flow for cleaning the weld area before welding and with a delay gives the signal to switch the welding machine on – thus enabling TIG welding with contactless arc ignition.



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 stages. The inductance control enables to optimize the characteristics of the arc depending on 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 element to be welded with MIG/MAG, the higher the inductance should be (soft arc – less fusion), for thicker elements the opposite (hard arc – more fusion).
