S307608-073 - Hobart Quantum Arc 6 ER70S-6 .035" 300lb Robotic Pack

High-Performance ER70S-6 Wire for Automated Systems

The Hobart Quantum Arc 6 is a premium mild steel solid wire formulated to meet the rigorous demands of robotic and high-volume semi-automatic welding applications. Classified as an AWS ER70S-6, this wire is engineered with elevated levels of manganese and silicon. These chemical components act as powerful deoxidizers, enabling the wire to produce sound, porosity-free welds even when applied to base metals exhibiting light rust, mill scale, or oil. This tolerance for surface contaminants makes Quantum Arc 6 an essential consumable for industrial manufacturing environments where pre-weld cleaning may not always be perfectly consistent.

One of the defining characteristics of the Quantum Arc 6 series is its superior feedability. In robotic cells, wire feeding issues can lead to arc failures, contact tip burn-back, and significant production downtime. Hobart has optimized the cast and helix of this wire, along with its copper coating, to ensure smooth, low-drag transmission through liners and guns. The 300lb Robotic Reel Pack (RRP) configuration further enhances efficiency by drastically reducing the frequency of spool changes compared to standard 33lb or 44lb spools. This bulk packaging is designed to integrate seamlessly with wire payoff systems used in automotive, heavy equipment, and general fabrication sectors.

Metallurgically, the wire provides excellent mechanical properties, typically yielding tensile strengths in the range of 86,000 psi. It is versatile regarding shielding gas, performing exceptionally well with both 100% Carbon Dioxide (CO2) for deep penetration and 75% Argon / 25% CO2 mixtures for reduced spatter and better bead aesthetics. The resulting weld deposits are characterized by a flat bead profile and excellent wetting, reducing the need for post-weld grinding. For facility managers and welding engineers seeking a reliable, high-throughput consumable that balances cost-efficiency with technical performance, the Hobart Quantum Arc 6 is a proven solution.
