S307615-045 - Hobart Quantum Arc 6 ER70S-6 MIG Wire .052" 45lb Steel Reel

Premium Mild Steel MIG Wire for Industrial Fabrication

The Hobart Quantum Arc 6 is a high-performance ER70S-6 solid welding wire designed to meet the rigorous demands of industrial manufacturing and structural steel fabrication. This specific spool features a 0.052-inch diameter wire packaged on a durable 45-pound steel reel, optimized for high-deposition applications where efficiency and weld quality are paramount. As a general-purpose mild steel wire, Quantum Arc 6 is formulated with elevated levels of manganese and silicon deoxidizers. These chemical additions provide exceptional cleaning action, allowing the wire to produce sound, porosity-free welds even when working with base metals that exhibit light rust, mill scale, or oil.

One of the standout characteristics of the Quantum Arc 6 is its excellent wetting action. The molten puddle flows smoothly, creating flat bead profiles with consistent tie-in at the toes of the weld. This reduces the need for post-weld grinding and cleanup, streamlining the production process. The wire is copper-coated, which not only enhances electrical conductivity for a stable arc but also protects the wire from corrosion during storage and improves contact tip life by reducing friction. It is engineered for versatility, performing reliably with both 100% Carbon Dioxide (CO2) and Argon/CO2 shielding gas mixtures.

This 0.052" variant is particularly well-suited for heavy-duty fabrication where higher amperage and deposition rates are required compared to standard 0.035" or 0.045" wires. The 45lb steel reel ensures a long run time between changeovers, maximizing arc-on time in automated or high-volume manual welding environments. Whether used for automotive components, heavy machinery, or general structural work, Hobart Quantum Arc 6 delivers the consistency and mechanical properties professional fabricators rely on.
