The non-copper coated OK AristoRod 12.50 is a manganese-silicon alloyed solid wire for GMAW of unalloyed steels, such as general structural, pressure vessel, ship-building and for fine-grained carbon-manganese steels for the same purpose with a minimum yield strength of max 420MPa. The electrode can be welded with Ar/20CO2 or with pure CO2 as the shielding gas. The Aristo Rod wires are suitable for operating at high currents with maintained disturbance-free wire feeding giving a stable arc with a low amount of spatter.
