EX70S6CF0000450M00 - Exocor ER70S-6 Copper Free MIG Wire .045" 44lb Spool

Advanced Metallurgy for Superior Feedability

The Exocor ER70S-6 Copper Free MIG Wire represents a significant advancement in welding consumable technology, specifically engineered to address the common limitations of traditional copper-coated wires. By utilizing a proprietary surface treatment instead of a copper coating, this .045-inch diameter wire eliminates the risk of copper flaking. In high-volume and robotic applications, copper flakes can accumulate in liners and contact tips, leading to erratic feeding, arc instability, and increased downtime for maintenance. This copper-free variant ensures consistent, uninterrupted feeding even through long conduit runs, making it a preferred choice for automated manufacturing environments.

Enhanced Environmental and Operator Safety

Beyond mechanical performance, the Exocor Copper Free wire offers tangible health and safety benefits. The absence of a copper coating significantly reduces the generation of copper-bearing fumes during the welding process. This contributes to a cleaner working environment and lowers the welder's exposure to metal fume hazards. Despite lacking the traditional copper layer, the wire is treated with a specialized inhibitor that provides excellent shelf-life and resistance to corrosion, ensuring the product remains ready for use even after storage.

Robust Performance on Structural Steel

Classified as an AWS ER70S-6, this wire is formulated with higher levels of Manganese and Silicon. These deoxidizers act as powerful cleaning agents within the weld pool, allowing the wire to perform exceptionally well on base metals that exhibit moderate amounts of rust, mill scale, or oil. The result is a sound, porosity-free weld with a smooth bead profile and excellent wetting characteristics. Whether used for general fabrication, structural steel erection, or heavy equipment repair, the Exocor ER70S-6 Copper Free wire delivers the mechanical properties and reliability required for critical industrial applications.
