OVERVIEW

Advanced Copper-Free Technology for Superior Welding Performance

The Exocor ER70S-6 Copper-Free MIG Welding Wire (0.030" diameter) represents a significant evolution in solid wire technology. Packaged in a substantial 44lb (20kg) spool, this wire is engineered for high-volume industrial fabrication where consistency and equipment longevity are paramount. The defining feature of this product is its specialized non-copper surface treatment. Traditional MIG wires rely on a thin layer of copper to prevent corrosion and aid electrical conductivity. However, that copper coating often flakes off during the feeding process, accumulating inside the liner and gun, leading to erratic feeding, arc instability, and frequent maintenance stops.

By utilizing a proprietary surface technology, Exocor has eliminated the need for copper coating while maintaining excellent conductivity and shelf-life. This Copper-Free (CF) design ensures that your wire feeders run cleaner for longer. Welders will experience a stable arc with significantly reduced spatter, which translates to less post-weld cleanup and grinding. Furthermore, the absence of copper reduces the specific welding fumes associated with copper vaporization, contributing to a healthier shop environment.

As an ER70S-6 class wire, it contains higher levels of manganese and silicon compared to S-3 wires. These deoxidizers act as cleaning agents within the molten weld pool, allowing this wire to perform exceptionally well on base metals that may have moderate amounts of rust, mill scale, or oil. It produces a flat, smooth bead with excellent wetting characteristics, making it a top choice for sheet metal applications where aesthetics matter. Whether you are welding structural plate or thin automotive sheet metal, this wire delivers the mechanical properties and operational efficiency required by professional fabricators.

Key Benefits:

  • Extended Consumable Life: No copper flaking means liners and tips last longer.
  • Cleaner Environment: Reduces metallic fume generation.
  • Versatile Performance: Handles dirty steel and clean sheet metal with equal ease.

FAQ

Copper-free wire eliminates the issue of copper flaking, which can clog wire liners and contact tips. This results in smoother feeding, a more stable arc, less equipment maintenance, and reduced welding fumes.

This wire can be used with 100% CO2 for deeper penetration and lower cost, or an Argon/CO2 mix (typically 75/25) for a smoother arc, less spatter, and better bead appearance.

Yes, the ER70S-6 classification indicates high levels of manganese and silicon deoxidizers, making it very capable of welding over moderate rust, mill scale, and oil without causing porosity.

This is a 44lb (20kg) spool. It typically requires an industrial wire feeder capable of holding large diameter spools (usually 12-inch diameter spools).

Yes, as a solid MIG wire, it can be used in all positions (flat, horizontal, vertical, and overhead), especially when using Short Circuit transfer mode with the .030" diameter.

No, Exocor uses a proprietary surface treatment that protects the wire from oxidation during storage, similar to how copper coating protects traditional wire.

This wire requires DCEP (Direct Current Electrode Positive), also known as Reverse Polarity.
