S307608-045 - Hobart Quantum Arc 6 ER70S-6 MIG Wire .035 45lb Spool

High-Performance ER70S-6 Solid MIG Wire

The Hobart Quantum Arc 6 is a premium mild steel solid wire formulated to meet the rigorous demands of industrial fabrication and automated welding environments. Classified as an AWS ER70S-6 electrode, this wire is engineered with higher levels of manganese and silicon deoxidizers compared to standard ER70S-3 wires. This enhanced chemical composition allows the Quantum Arc 6 to effectively manage weld pools on base metals that exhibit light rust, mill scale, or oil, ensuring sound, porosity-free welds even when surface preparation is not perfect.

Designed for versatility and consistency, this 0.035-inch diameter wire performs exceptionally well with both 100% CO2 and 75% Argon/25% CO2 shielding gas mixtures. The wire's copper-coated finish ensures excellent electrical conductivity and protects the wire from oxidation during storage. One of the standout features of the Quantum Arc 6 is its superior feedability. Hobart has optimized the wire's surface characteristics and cast/helix properties to minimize drag and friction in the liner, making it an ideal choice for robotic, automatic, and semi-automatic welding applications where wire feeding issues can cause costly downtime.

The 45lb spool size is perfectly suited for high-volume production shops, reducing the frequency of spool changes and maximizing arc-on time. Whether used for single-pass or multiple-pass applications, the Quantum Arc 6 delivers a flat to slightly convex bead profile with excellent wetting action. It is widely utilized in the manufacturing of automotive frames, farm implements, construction equipment, pressure vessels, and railcars. The wire supports a wide range of wire feed speeds, from moderately slow to very fast, without compromising arc stability or bead appearance.

By choosing Hobart Quantum Arc 6, fabricators gain a reliable consumable that balances forgiveness on contaminants with high-speed performance. Its ability to bridge gaps and handle varying fit-up conditions makes it a staple in general fabrication and structural steel work. The consistent quality control from Hobart ensures that every spool delivers the same arc characteristics, allowing weld procedures to remain stable over long production runs.
