ESAB 1251096710 Solid MIG Wire

The ESAB 1251096710 OK Autrod 12.51 Solid MIG Wire is a copper-coated ER70S-6 welding wire, designed for MIG (GMAW) welding of carbon steel. With higher levels of deoxidizers (manganese and silicon), this wire provides excellent tolerance to rust, dirt, and mill scale, ensuring clean, strong welds with minimal defects. It is ideal for structural fabrication, automotive manufacturing, and general metalworking applications, delivering a smooth, fluid weld puddle and consistent bead profile.

This 0.035″ (0.9mm) wire is compatible with 100% CO₂ and 75% Ar/25% CO₂ shielding gases, offering versatile welding options. With a tensile strength of up to 81 ksi, this wire produces high-strength, ductile welds suitable for heavy-duty applications. The 18 kg (39.7 lb) spool ensures extended welding time, reducing downtime and increasing productivity.

Features:

• ER70S-6 Copper-Coated Wire: Improves electrical conductivity, corrosion resistance, and arc stability.
• Higher Deoxidizer Content: Enhances weld quality, allowing welding over rust, dirt, and mill scale.
• Smooth, Fluid Weld Pool: Provides excellent bead appearance with minimal spatter.
• High Strength & Ductility: Delivers tensile strength of up to 81 ksi, ensuring strong, durable welds.
• Versatile Shielding Gas Compatibility: Works with 100% CO₂ and 75% Ar/25% CO₂ shielding gases.
