OK Autrod 12.56
GMAW
A copper-coated, manganese-silicon-alloyed electrode for the GMAW of unalloyed steels, such as general structural steels with a minimum tensile strength of no more than 510 MPa, and for fine-grained, carbon-manganese steels with a minimum yield strength of 360 MPa. OK Autrod 12.56 can be welded with Ar/20CO2 or pure CO2 as the shielding gas. The mechanical properties quoted here are welded with Ar/20CO2 as the shielding gas.
