Welding wire used for welding in the gas medium (MIG / MAG) of general structural steels, tubular steels and cast steels. Depending on the thickness of the parent metal, CO2 (carbon dioxide) or gas mixtures can be used as a protective gas. Typically, it is used for steel structures and shipbuilding, machine tools, tanks, boilers, metal products and the automotive industry. Depending on the thickness of the material to be welded and the equivalent of carbon, preheating is recommended. A thin and uniform copper coating increases the electrical conductivity and resistance of the wire to corrosion.
