Paton ProMIG 350 (15-4) welder inverter with water cooling – basic information

The Paton ProMIG 350 15-4 welder inverter is designed for semi-automatic MIG/MAG welding with gas and protective mixtures, manual MMA arc welding and argon shielded TIG welding with direct current.


The design of the ProMIG 350 15-4 model (15kg spool – 4 roller feeder) provides some of the best protection against external influences on the market. This model’s rated current of 350A at a duty cycle of 70% is a result that allows intensive welding of materials without the risk of overheating. The power source can be separated from the welding wire feed mechanism for convenience as well as safety. A distinctive feature of the PATON™ Professional Series semi-automatic machines is the high-quality, sealed, metallic wire feeder, as well as the existing KZ-2 “EURO” type connector, which has become a standard worldwide, allowing the user to change the handle at will in the future.


In a fully electronic system, the control system has absolutely all the resources of the source, within the limits of its full capacity and whatever method is used. The ‘Professional’ series is designed for industrial use, for the most demanding users.


Functions and features of the Paton ProMIG 350 (15-4) 400V welder inverter

All PATON MIG/MAG welders are suitable for welding with self-consuming wire. Such welding, as opposed to the traditional MIG/MAG welding process, takes place without shielding gas – however, this requires a special welding wire. Such wire produces its own shielding, which helps to protect the welding arc. Self-shielded wire suitable for PATON welders can be purchased here – spools of 5 kg 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 stages. 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 workpiece to be welded using MIG/MAG, the higher the inductance should be (soft arc – less fusion), for thick workpieces the opposite (hard arc – more fusion).



– PULSE in TIG welding – full control of heat input into 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,

– PULSE in MIG/MAG welding – easier detachment of metal droplets from the end of the electrode wire, adjustable pulse current parameters. MIG welding with pulsation is useful for welding stainless steels, acid-resistant steels and aluminium alloys. In addition, pulse welding provides better performance when soldering CuSi3


Main advantages of the Paton ProMIG 350 15-4 400V welder inverter
