OVERVIEW

Industrial Grade ER70S-6 Solid MIG Wire

The Hobart Quantum Arc 6 is a premium mild steel solid wire designed to meet the rigorous demands of industrial manufacturing and fabrication. Classified as an AWS ER70S-6 electrode, this wire is formulated with higher levels of manganese and silicon compared to standard S3 wires. These added deoxidizers act as powerful cleaning agents within the weld puddle, allowing the Quantum Arc 6 to perform exceptionally well on base metals that exhibit light rust, mill scale, or oil. This makes it a versatile choice for structural steel shops where surface preparation cannot always be perfect.

Engineered for consistency, this .045-inch diameter wire features a high-quality copper coating. The copper plating serves two critical functions: it enhances electrical conductivity for a stable arc transfer and protects the wire from corrosion during storage. The wire is precision-wound onto a 60-pound fiber spool, a packaging format that bridges the gap between standard hand-held spools and bulk drums. This larger capacity is specifically advantageous for high-volume workstations and robotic cells, significantly reducing the frequency of spool changeovers and maximizing arc-on time.

The Quantum Arc 6 is optimized for use with both 100% Carbon Dioxide (CO2) and Argon/CO2 blends (typically 75/25). When used with a mixed gas, operators can achieve a smooth spray transfer mode with minimal spatter, resulting in clean, aesthetically pleasing weld beads that require little post-weld cleanup. The wire's stiffness and cast are controlled to ensure trouble-free feeding through long conduit liners and MIG gun cables, a critical factor for maintaining weld quality in automated setups.

Technical Specifications

This wire delivers a minimum tensile strength of 70,000 psi, meeting the requirements for welding mild and low-alloy steels. It is suitable for single-pass and multi-pass applications in all positions (depending on the mode of transfer). The 60lb fiber spool is designed to be eco-friendly and easy to dispose of compared to traditional plastic or steel reels.

FAQ

It is classified as ER70S-6, which indicates a mild steel solid wire with high deoxidizers (manganese and silicon) and a minimum tensile strength of 70,000 psi.

This wire can be used with 100% CO2 for deeper penetration and lower cost, or a blend of 75% Argon / 25% CO2 for a smoother arc, less spatter, and better bead appearance.

Yes, the ER70S-6 classification means it contains higher levels of deoxidizers that allow it to handle light to moderate rust, mill scale, and oil on the base metal better than ER70S-3 wires.

This specific product comes on a 60 lb (approx. 27.2 kg) fiber spool, which is larger than standard 33 lb or 44 lb spools.

Yes, Hobart Quantum Arc 6 is known for its excellent feedability and consistent arc characteristics, making it highly suitable for robotic and automatic welding applications.

This wire has a diameter of 0.045 inches (1.2 mm), which is a common size for welding medium to heavy plate thicknesses.

Yes, it is a copper-coated wire. The coating improves electrical contact, reduces tip wear, and helps prevent the wire from rusting during storage.

This solid MIG wire requires Direct Current Electrode Positive (DCEP), also known as Reverse Polarity.
