The TIG 315 AC / DC welding machine combines all the functionalities of TIG and MMA welding

It allows the welder to weld a wide range of metals such as steel, stainless steel, aluminum, magnesium, aluminum alloys, titanium and copper. It is equipped with a 32-bit microprocessor, which allows it a full range of settings to achieve the best possible welding results.

The TIG 315 AC / DC welding machine supports DC and AC welding. We weld all steels, stainless steels, special metals and their alloys with direct welding, and aluminum, magnesium and their alloys with alternating current.

Due to its properties and adjustability, the TIG 315 AC / DC welding machine is suitable for every welder and for every professional or home workshop.
