EX70S6CF0000350M00 - Exocor ER70S-6 Copper-Free MIG Wire 0.035 44lb Spool

Premium Copper-Free Mild Steel MIG Wire

The Exocor ER70S-6 Copper-Free MIG Welding Wire (0.035") represents a significant advancement in consumable technology for mild steel fabrication. Unlike traditional copper-coated wires, this "CF" variant features a proprietary surface treatment that ensures excellent electrical conductivity and corrosion resistance without the use of a copper layer. This design eliminates the common issue of copper flaking, which can clog gun liners and contact tips, leading to erratic feeding and increased downtime. It is an exceptional choice for high-volume production environments and automated welding cells where consistency is paramount.

As an ER70S-6 classification wire, it is formulated with higher levels of manganese and silicon deoxidizers compared to S-3 wires. This chemical composition allows the wire to handle base metals with moderate amounts of rust, mill scale, and oil, producing sound welds with minimal porosity. The 0.035-inch diameter is the industry standard for a wide range of material thicknesses, offering a perfect balance between deposition rate and control on thinner sheet metals.

Packaged in a 44lb (20kg) spool, this product is designed for industrial users who require longer run times between spool changes. The wire produces a stable arc with low spatter, resulting in aesthetically pleasing weld beads that require less post-weld cleanup. Whether used with 100% CO2 for deep penetration or an Argon/CO2 mix for a smoother arc, Exocor's copper-free wire delivers reliable performance for critical structural and general fabrication tasks.
