Application Areas and Properties
It is a copper-coated gas-shielded (MIG/MAG) welding wire used for welding unalloyed, structural, and fine-grained steels in constructions, machinery, tanks, boilers, pipes, thin sheets, car bodies, steel furniture, panels, and metal goods, as well as in the automotive industry. The homogeneous and appropriately thick copper coating improves electrical conductivity and increases resistance to corrosion.
Depending on the base metal thickness, CO₂ (carbon dioxide) or mixed gases (Ar+CO₂) can be used as shielding gas. It can operate at temperatures up to 400 °C.
