OK AristoRod 12.57

The non‑copper coated OK AristoRod 12.57 is a manganese‑silicon solid MIG wire for welding unalloyed steels such as structural, pressure vessel and shipbuilding steels (≥500 MPa tensile strength) and fine‑grained carbon‑manganese steels (≤400 MPa yield strength). It can be used with Ar/20CO₂ or pure CO₂ shielding gases and is suitable for high‑current welding.
