Magmaweld MG2 is unalloyed wire electrode for GMA (MIG/MAG) welding of general structural steels, pipes and cast steels by using CO2 or mixed shielding gases can be used depending on thickness of the base metal. Generally used in steel construction, shipbuilding, machine, tank, boiler production, automotive industry. Preheating is required, depending on the plate thickness and carbon equivalent of the base metal. A thin and homogeneous copper coating increases electrical conductivity and protects the wire from rusting.
