OK Autrod 12.51 is a copper-coated solid wire with higher levels of deoxidisers (manganese and silicon). The high content of deoxidisers allow welding over heavier amounts of dirt, rust, and mill scale while providing a more fluid puddle and smoother bead profile.
Copper coated Mn-Si-alloyed solid wire.
Suitable for GMAW of non-alloyed steels.
Can be used with Ar/CO2 mixed and pure CO2 shielding gas.
