S307612-070 - Hobart Quantum Arc 6 ER70S-6 MIG Wire .045 950lb Drum

High-Performance ER70S-6 Solid Wire for Industrial Automation

The Hobart Quantum Arc 6 is a premium mild steel solid wire formulated to meet the rigorous demands of high-speed, high-volume manufacturing environments. Classified as an AWS ER70S-6, this wire is engineered with elevated levels of manganese and silicon. These chemical deoxidizers serve a critical function during the welding process by scavenging oxygen and impurities from the weld pool. This chemical composition allows the Quantum Arc 6 to perform exceptionally well on base metals that exhibit light rust, mill scale, or oil, ensuring sound weld deposits with minimal porosity even in less-than-ideal surface conditions.

Designed specifically for robotic, automatic, and semi-automatic applications, this product features superior feedability characteristics. The wire surface and copper coating are optimized to reduce friction within liners and contact tips, ensuring consistent wire delivery at wire feed speeds ranging from moderately slow to very fast. This consistency is paramount in robotic cells where arc instability or burn-backs can cause significant production downtime. The 950 lb Robo-Pak (Rrp) configuration further enhances operational efficiency by drastically reducing the frequency of spool changes compared to standard 33lb or 44lb spools, maximizing arc-on time for continuous manufacturing workflows.

Quantum Arc 6 offers versatility in shielding gas selection, operating effectively with both 100% Carbon Dioxide (CO2) and Argon/CO2 blends (typically 75/25). It produces a fluid weld puddle with excellent wetting action, resulting in a flat bead profile and smooth tie-ins at the toes of the weld. This reduces the need for post-weld grinding or cleanup. Mechanical properties of the deposited weld metal meet or exceed AWS A5.18 requirements, providing reliable tensile and yield strength for structural applications. It is an ideal choice for industries requiring consistent, high-quality welds on carbon steel components.
