S307615-028 - Hobart Quantum Arc 6 ER70S-6 .052 Solid MIG Wire 60lb Spool

Technical Overview: Hobart Quantum Arc 6 ER70S-6 Wire

The Hobart Quantum Arc 6 is a premium mild steel solid wire designed to meet the rigorous demands of industrial fabrication. Classified as an AWS ER70S-6, this wire is formulated with elevated levels of manganese and silicon. These chemical elements act as powerful deoxidizers, scavenging oxygen and impurities from the weld pool. This chemical composition makes Quantum Arc 6 particularly effective when welding on base metals that exhibit light rust, mill scale, or oil, ensuring sound welds with minimal porosity even in less-than-ideal surface conditions.

This specific SKU (S307615-028) features a wire diameter of .052 inches, a size often selected for heavy fabrication where higher deposition rates are required compared to standard .045 wires, yet it retains better puddle control than larger 1/16" wires. The product is supplied on a 60lb fiber spool, designed for high-volume users who require longer run times between spool changes. The wire is copper-coated, which enhances electrical conductivity at the contact tip and provides resistance to corrosion during storage.

Engineered for versatility, Quantum Arc 6 operates efficiently with both 100% CO2 and Argon/CO2 blends (typically 75/25). While CO2 provides deeper penetration, the Argon blend offers a smoother arc and reduced spatter. The wire's manufacturing process ensures tight tolerance on diameter and cast/helix, resulting in superior feedability. This makes it an excellent choice for robotic and automated welding cells where wire feeding issues can cause costly downtime. Mechanical properties typically yield tensile strengths exceeding 86,000 PSI, meeting or exceeding AWS A5.18 requirements.
