ER70S-6 Solid MIG Welding Wire – .035” – 11 lb Spool

Key features

• AWS ER70S-6 Classification: Solid MIG welding wire formulated for mild and carbon steel applications
• .035 in (0.9 mm) Diameter: Ideal for welding thicker materials with higher deposition rates
• 11 lb Spool: Designed for extended welding jobs and professional shop use
• Copper-Coated Wire: Promotes consistent wire feeding and stable arc performance
• Shielding Gas Required: Compatible with CO₂ or Argon/CO₂ gas mixtures for GMAW processes
• Enhanced Deoxidizers: Increased silicon and manganese content helps reduce porosity on lightly scaled or dirty steel

Copper Bridge ER70S-6 Solid MIG Welding Wire is a copper-coated solid wire designed for mild steel MIG (GMAW) welding applications. The ER70S-6 classification provides enhanced silicon and manganese content to improve weld quality and reduce porosity when working with light mill scale or slightly contaminated steel. The .035 in (0.9 mm) diameter is commonly used for thicker materials and higher deposition rates. Supplied on an 11 lb spool, this wire is suitable for use with CO₂ or Argon/CO₂ shielding gas in fabrication, repair, and general shop welding environments.
