Copper-coated solid wire designed for welding carbon and carbon-manganese steels with tensile strength up to 510 MPa. Suitable for single pass or multi-pass welding. Applications include tanks, boilers, steel structural works, earthworks and construction works. The higher silicon-manganese content improves high mechanic characteristics and gives better deposit. To be used under the shield of Ar+CO2 or CO2.
