S307610-085 - Hobart Quantum Arc 6 ER70S-6 Copper-Free MIG Wire .040 45lb Spool

High-Performance Copper-Free Mild Steel MIG Wire

The Hobart Quantum Arc 6 is a premium mild steel solid wire designed to meet the rigorous demands of industrial manufacturing and heavy fabrication. Classified as an AWS ER70S-6, this wire is formulated with high levels of manganese and silicon deoxidizers, making it exceptionally capable of handling base metals with light-to-moderate rust and mill scale. What sets the Quantum Arc 6 apart is its advanced copper-free surface technology. Unlike traditional copper-coated wires, this product eliminates the risk of copper flaking, which is a common cause of liner clogging and premature contact tip failure in high-volume welding environments.

With a diameter of 0.040 inches, this wire offers a unique balance between the deposition rates of .045 wire and the control of .035 wire, making it suitable for a wide range of material thicknesses. The absence of a copper coating does not compromise conductivity; rather, it enhances arc starting and stability while reducing the generation of particulate fumes associated with copper. This makes it an excellent choice for enclosed environments or facilities prioritizing air quality management. The wire is precision-wound on a 45lb fiber spool, ensuring tangle-free feeding and compatibility with standard industrial wire feeders.

Engineered for both semi-automatic and robotic applications, the Quantum Arc 6 delivers a smooth, stable arc with minimal spatter. This reduction in spatter translates to less post-weld cleanup and higher productivity. The wire's superior wetting characteristics ensure flat, consistent bead profiles with excellent tie-in, crucial for structural integrity in automotive frames, heavy machinery, and general construction. By choosing Hobart Quantum Arc 6, fabricators invest in reliability, reduced downtime, and superior weld quality.
