S307308-033 - Hobart Quantum Arc 3 ER70S-3 .035 MIG Wire 33lb Reel

Premium ER70S-3 Solid Wire for Clean Steel Applications

The Hobart Quantum Arc 3 is a high-performance ER70S-3 solid MIG welding wire designed specifically for general fabrication where the base material is clean and free of heavy rust or mill scale. Unlike the more common ER70S-6, which contains higher levels of deoxidizers to combat contaminants, the ER70S-3 formulation in Quantum Arc 3 is balanced to provide a cleaner weld bead with significantly fewer silica islands. This characteristic makes it an exceptional choice for multi-pass welding applications where inter-pass cleaning must be minimized to maintain production efficiency.

Engineered for consistency, this wire features a high-quality copper coating that ensures excellent electrical conductivity and smooth feeding through liners and contact tips. This reliability is critical for robotic and semi-automatic welding environments where wire feed issues can lead to costly downtime. The wire produces a stable arc with low spatter levels whether used with 100% CO2 or Argon/CO2 shielding gas blends, offering versatility across different shop setups. The 33 lb steel reel packaging provides a robust mounting solution that resists damage in industrial environments.

Metallurgically, the Quantum Arc 3 provides a fast-freezing puddle, which is advantageous for high-speed welding on light gauge sheet metal, such as in automotive frame manufacturing. While it requires cleaner base metal preparation than S-6 wires, the payoff is a superior bead profile and reduced post-weld finishing. It is suitable for single and multiple pass applications and meets AWS A5.18 specifications.
