S307612-045 - Hobart Quantum Arc 6 ER70S-6 MIG Wire .045 45lb Reel

Premium ER70S-6 Solid MIG Wire for Industrial Fabrication

The Hobart Quantum Arc 6 is a high-performance mild steel solid wire designed to meet the rigorous demands of modern industrial manufacturing. Classified as an AWS ER70S-6, this wire is engineered with elevated levels of manganese and silicon deoxidizers. These chemical properties allow the wire to tolerate light to moderate amounts of surface contaminants, such as rust and mill scale, without compromising the structural integrity of the weld deposit. This makes it an exceptional choice for general fabrication environments where surface preparation may not always be perfect.

One of the defining characteristics of the Quantum Arc 6 is its superior feedability. The wire features a high-quality copper coating that ensures excellent electrical conductivity and protects against corrosion during storage. The precision winding on the 45 lb steel reel ensures a consistent cast and helix, which is critical for minimizing friction in the liner and contact tip. This consistency makes the Quantum Arc 6 particularly well-suited for robotic and automatic welding applications where downtime due to feeding issues must be minimized. The wire supports wire feed speeds ranging from moderately slow to very fast, providing flexibility across various production cycles.

Metallurgically, the wire produces a flat bead profile with excellent wetting action, ensuring smooth tie-ins at the toes of the weld. It is compatible with both 100% Carbon Dioxide (CO2) and Argon/CO2 blends (typically 75/25), allowing operators to tailor the shielding gas to the specific penetration and spatter requirements of the job. Whether used for single-pass welds on sheet metal or multi-pass welds on heavy plate, the Quantum Arc 6 delivers reliable mechanical properties and consistent X-ray quality welds.
