Mig Wire SupER 6 ER70S6 .035 20kg Spool

High-Performance Deoxidation for Industrial Fabrication

The Super 6 ER70S-6 .035" MIG Welding Wire is a premium mild steel solid wire formulated to meet the rigorous demands of industrial manufacturing and structural fabrication. Classified under AWS A5.18, this ER70S-6 electrode is characterized by its elevated levels of manganese and silicon. These chemical additions serve as powerful deoxidizers, scavenging oxygen from the weld pool and significantly reducing the risk of porosity. This makes the Super 6 wire particularly effective when welding base metals that exhibit light rust, mill scale, or oil, where standard S-3 wires might fail to produce a sound weld.

Engineered for consistency, this wire features a precision copper coating that enhances electrical conductivity at the contact tip, ensuring stable arc transfer and reduced tip wear. The 20kg (44lb) spool size is optimized for high-volume production environments, reducing downtime associated with frequent spool changes. The wire exhibits excellent feedability, minimizing bird-nesting and liner friction even over long conduit runs. Its mechanical properties meet or exceed the 70,000 psi tensile strength requirement, providing robust structural integrity for critical joints.

The weld puddle created by this wire is highly fluid, allowing for excellent wetting action at the toes of the weld. This results in a flat, smooth bead profile that requires minimal post-weld grinding. It is compatible with both 100% CO2 and Argon/CO2 shielding gas mixtures, offering versatility across different welding procedures and transfer modes, including short-circuit, globular, and spray transfer.

Technical Specifications and Metallurgy

The "S-6" designation indicates the highest level of silicon and manganese in the carbon steel wire class. This chemistry not only aids in deoxidation but also improves the fluidity of the puddle, making it easier for the operator to manipulate the arc and achieve proper fusion. This wire is suitable for single-pass and multi-pass applications on carbon steels, making it a staple for heavy equipment manufacturing, automotive frames, and general construction.
