4470S6035 - Canweld ER70S-6 0.035 Inch 44lb Mild Steel MIG Wire

High-Performance ER70S-6 Solid MIG Wire for Industrial Fabrication

The Canweld ER70S-6 0.035" MIG Wire (44lb Spool) is a premium mild steel solid wire designed to meet AWS A5.18 specifications. Engineered for the Gas Metal Arc Welding (GMAW) process, this consumable is characterized by its elevated levels of silicon and manganese. These chemical deoxidizers are critical for mitigating the effects of oxygen trapped in the weld pool, making this wire the preferred choice for welding on base metals that exhibit moderate amounts of rust, mill scale, or oil. The "S6" classification indicates a higher deoxidizer content compared to ER70S-3, providing superior cleaning action and reducing the risk of porosity in the final weldment.

In terms of weldability, this wire exhibits excellent wetting characteristics, resulting in a fluid weld pool that ties in smoothly at the toes of the weld. This high fluidity contributes to a flat bead profile and minimizes the need for extensive post-weld grinding or cleanup. The wire is copper-coated to ensure optimal electrical conductivity and to protect the steel from corrosion during storage. This coating also aids in smooth feeding through the liner and contact tip, reducing friction and preventing arc instability caused by feed fluctuations.

This 44lb (20kg) spool is designed for industrial wire feeders and is suitable for both single-pass and multi-pass applications. It operates effectively with 100% CO2 shielding gas for deeper penetration and economy, or with an Argon/CO2 blend (typically 75/25) for reduced spatter and a cleaner bead appearance. With a minimum tensile strength of 70,000 psi, it is ideal for structural steel, general fabrication, and heavy equipment repair where weld integrity is paramount. The consistent diameter control ensures reliable performance in automated and semi-automatic welding environments.
