S307212-073 - Hobart Quantum Arc ER80S-D2 .045 Solid MIG Wire 300lb Drum

High-Performance Low-Alloy MIG Wire for Automation

The Hobart Quantum Arc D2 .045" MIG Wire is a premium low-alloy solid wire formulated to meet the rigorous demands of high-strength steel fabrication. Classified as AWS ER80S-D2, this wire is alloyed with approximately 0.50% molybdenum and high levels of manganese. This specific chemical composition provides significant advantages over standard mild steel wires (such as ER70S-6), specifically in terms of tensile strength and ductility. The addition of molybdenum enhances the weld deposit's mechanical properties, making it capable of maintaining strength even at elevated service temperatures, while the manganese content serves as a powerful deoxidizer, helping to scavenge impurities and reduce porosity when welding on base metals with light rust or mill scale.

One of the standout features of the Quantum Arc series is its advanced surface engineering. In robotic and automated welding environments, wire feeding issues are a primary cause of downtime. Hobart has designed the Quantum Arc D2 with a proprietary surface finish that optimizes electrical conductivity and minimizes friction within the liner. This results in an extremely stable arc and consistent wire placement, which is critical for the repeatability required in robotic cells. The 300 lb Robotic Reel-less Pack (RRP) is specifically configured for high-volume manufacturing, reducing the frequency of changeovers and maximizing arc-on time.

This wire is an ideal choice for fabricating High-Strength Low-Alloy (HSLA) steels often found in heavy industrial sectors. It produces X-ray quality welds with excellent bead aesthetics and minimal spatter, reducing post-weld cleanup time. Whether used with 100% CO2 for deep penetration or an Argon/CO2 blend for a smoother spray transfer, the Hobart Quantum Arc D2 delivers reliable, high-performance results for critical structural components.
