Price range: $37.45 through $89.45 inc. GST
Manganese-silicon alloyed MIG wire for mild steel, designed for high-current GMAW with excellent arc stability and minimal spatter. Suitable for CO₂ and mixed gases.
Description
ESAB OK AristoRod 12.50 Solid Wire
ESAB OK AristoRod 12.50 is a non-copper coated, manganese-silicon alloyed solid wire designed for GMAW (MIG) welding of unalloyed steels. It is ideal for structural applications, pressure vessels, shipbuilding, and fine-grained carbon-manganese steels with a minimum yield strength up to 420 MPa.
Engineered for consistent wire feeding, this wire performs exceptionally well under high current settings, delivering a stable arc and reduced spatter. It is suitable for use with pure CO₂ or mixed shielding gases (M20/M21), and performs reliably in mechanised or automated applications.
This wire is also available in ESAB’s unique Octagonal Marathon Pac for uninterrupted wire feeding in high-volume operations.
