OVERVIEW

High-Performance ER70S-6 Solid Wire for Industrial Applications

The ER70S-6 .023" Mild Steel MIG Wire is a premium general-purpose welding consumable designed for the Gas Metal Arc Welding (GMAW) process. Engineered to meet AWS A5.18 specifications, this solid wire is formulated with higher levels of manganese and silicon compared to standard ER70S-3 wires. These added deoxidizers significantly enhance the wire's ability to handle base metals with light to moderate mill scale, rust, or oil, ensuring sound, porosity-free welds in less-than-perfect surface conditions.

This 11lb (5kg) spool is precision layer-wound to ensure tangle-free feeding, which is critical for maintaining a stable arc and consistent weld bead profile. The wire features a high-quality copper coating that serves a dual purpose: it protects the steel from oxidation during storage and improves electrical conductivity at the contact tip, reducing tip wear and promoting smoother arc initiation. With a tensile strength exceeding 70,000 PSI, this wire is suitable for structural applications requiring robust mechanical properties.

The 0.023-inch diameter is specifically optimized for low-amperage welding on thin-gauge materials, making it an essential inventory item for fabrication shops dealing with sheet metal, HVAC ductwork, and light structural components. It operates exceptionally well in the short-circuit transfer mode, providing a controllable puddle that minimizes burn-through on delicate substrates. Compatible with both 100% CO2 for deeper penetration and Argon/CO2 blends (typically C25) for a smoother arc and reduced spatter, this wire offers flexibility for various industrial setups.

FAQ

For the best performance and least spatter, a mix of 75% Argon and 25% CO2 (C25) is recommended. You can also use 100% CO2, which provides deeper penetration but may result in slightly more spatter.

This is a solid steel wire (ER70S-6) and requires an external shielding gas to protect the weld pool. It is NOT flux-cored.

Solid MIG wire like ER70S-6 requires DCEP (Direct Current Electrode Positive), also known as Reverse Polarity.

This 11lb spool typically has an 8-inch diameter and a 2-inch center arbor hole. It fits most MIG welders rated from 140 amps up to 250 amps that accept 8-inch spools.

Yes, the ER70S-6 classification contains higher levels of silicon and manganese deoxidizers, making it better suited for welding steel with light rust or mill scale compared to ER70S-3 wire.

The '70' in ER70S-6 indicates a minimum tensile strength of 70,000 PSI, making it suitable for most mild steel structural applications.

Yes, for optimal feeding, you should use a liner designed for .023" wire. Using a liner meant for much larger wire (like .035" or .045") can cause the thin wire to buckle or feed inconsistently.

The copper coating helps prevent oxidation. If stored in a dry, low-humidity environment (preferably in its original plastic packaging with desiccant), the wire can last for years without rusting.
