S307612-074 - Hobart Quantum Arc 6 ER70S-6 .045" MIG Wire - 600lb Drum

Industrial Grade ER70S-6 Solid Wire for Automation

The Hobart Quantum Arc 6 is a high-performance mild steel solid wire designed specifically to meet the rigorous demands of robotic and high-speed automated welding applications. Classified as an AWS ER70S-6, this wire is formulated with higher levels of manganese and silicon deoxidizers compared to standard ER70S-3 wires. This chemical composition allows the Quantum Arc 6 to effectively handle base metals that may have light rust, oil, or mill scale, ensuring sound, porosity-free welds in industrial manufacturing environments.

One of the standout features of the Quantum Arc 6 is its superior feedability. In robotic cells, wire feeding issues can cause costly downtime and weld defects. Hobart has engineered this wire with precise diameter control, consistent cast, and helix, and a high-quality copper coating to ensure smooth transmission through liners and contact tips. This results in a stable arc, reduced contact tip wear, and fewer burn-backs, even at the high wire feed speeds typical of automotive and heavy equipment fabrication.

This product is supplied in a 600lb Robo Pak drum, a bulk packaging solution designed to maximize arc-on time by significantly reducing the frequency of spool changes. The drum format is ideal for high-volume production lines where efficiency is paramount. The wire operates effectively with both 100% CO2 and 75% Argon / 25% CO2 shielding gas blends, offering flexibility depending on the required penetration profile and spatter control. Whether used for single-pass or multi-pass applications, the Hobart Quantum Arc 6 delivers consistent mechanical properties and excellent bead appearance.

Key Industrial Applications

This wire is widely utilized in sectors requiring high throughput and structural integrity, including the manufacturing of automotive frames, railcars, agricultural implements, and pressure vessels. Its ability to bridge gaps and wet out smoothly makes it a versatile choice for general fabrication shops transitioning to automated solutions.
