EX70S6CF0000350MD5 - Exocor ER70S-6 Copper-Free MIG Wire .035 Drum

High-Performance ER70S-6 Wire for Automated Welding

Maximize your production throughput with Exocor's .035" Copper-Free ER70S-6 MIG Wire, supplied in a bulk 550lb drum. This solid wire is specifically formulated to meet the rigorous demands of structural steel fabrication, automotive manufacturing, and general heavy-duty welding. The "Copper-Free" designation refers to the absence of a copper coating, replaced instead by an advanced surface technology that promotes superior electrical transfer and arc starting.

Why Choose Copper-Free?

In continuous welding operations, particularly those utilizing long conduit runs or robotic arms, copper-coated wires can shed fine copper flakes. Over time, this debris clogs liners and fuses to contact tips, leading to "burn-backs" and unstable arcs. Exocor's copper-free wire solves this problem at the source, providing a clean, low-friction feed that maintains arc stability shift after shift. This results in significantly reduced wear on torch consumables and less unplanned maintenance.

Weld Quality and Versatility

As an ER70S-6 class wire, it contains higher levels of silicon and manganese compared to S-3 wires. These deoxidizers act as scavenging agents, floating impurities to the surface and allowing for sound welds even on dirty or scaled steel. The resulting weld deposit offers high tensile strength and excellent ductility. The wire produces a flat, smooth bead profile with excellent tie-in, suitable for single or multi-pass applications.

Bulk Packaging for Efficiency

The 550lb drum format is essential for shops looking to streamline operations. By reducing the number of changeovers compared to standard 33lb or 44lb spools, operators can keep the arc lit longer. Note that a drum pay-off kit and appropriate conduit are required to dispense wire from this package effectively.
