The ESAB OK AristoRod 12.50 is the industry leader in non-copper coated solid MIG wires. This 1.2mm (0.045″) variant is designed for high-deposition welding on medium-to-heavy structural steel. Using ESAB’s Advanced Surface Characteristics (ASC), the wire is engineered to provide superior feedability and arc stability without the copper flaking that typically clogs liners and contact tips. 

Packaged in an 18kg spool, it is perfect for structural fabrication, transport equipment, and heavy machinery manufacturing where deep penetration and high duty cycles are required.
