OVERVIEW

High-Performance Deoxidizing MIG Wire for Industrial Applications

The Murex ER70S-6 .035" Solid Mild Steel MIG Wire is engineered for professional fabrication environments requiring robust mechanical properties and forgiveness on less-than-perfect base metals. As an S6 classification wire, it contains higher levels of silicon and manganese compared to standard ER70S-3 or ER70S-4 consumables. These added deoxidizers act as powerful scavenging agents, allowing the molten weld pool to float out impurities found in mill scale, light rust, and oil. This results in a cleaner, sounder weld deposit with reduced porosity defects, making it the preferred choice for general structural steel fabrication where surface preparation cannot always be perfect.

This 44lb spool is designed for high-volume industrial wire feeders, minimizing downtime associated with frequent spool changes. The wire features a precision copper coating that serves two critical functions: it enhances electrical conductivity at the contact tip for a stable arc, and it reduces friction within the liner and gun, ensuring smooth, consistent feeding even over long conduit runs. The controlled cast and helix of the wire further prevent tangling and birdnesting, which is essential for automated or semi-automated processes.

Ideally suited for single-pass welds on sheet metal as well as multiple-pass welds on thicker sections, this wire exhibits excellent wetting characteristics. The fluid puddle flows out smoothly to the toes of the weld, creating a flat bead profile that requires minimal post-weld grinding. It operates effectively with 100% CO2 for deep penetration or Argon/CO2 blends for reduced spatter and better arc control. Whether used in the manufacturing of agricultural machinery, automotive repair, or heavy construction equipment, this Murex wire delivers reliable, code-quality results.

FAQ

This ER70S-6 wire works well with 100% CO2 for deeper penetration and lower cost, or an Argon/CO2 mix (typically 75/25) for a smoother arc, less spatter, and better bead appearance.

Yes, the ER70S-6 classification indicates higher levels of silicon and manganese deoxidizers, making it excellent for welding on steel with moderate rust, mill scale, or oil compared to S3 or S4 wires.

This is a 44lb (20kg) spool, typically used on industrial wire feeders and larger MIG machines. It requires a standard 2-inch spindle hub adapter.

Yes, this solid wire can be used for all-position welding (flat, horizontal, vertical, overhead), provided you use the correct transfer mode (usually short-circuit for out-of-position work).

ER70S-6 contains higher levels of deoxidizers (manganese and silicon) than ER70S-3. This allows S6 to handle dirtier base metals better and provides a more fluid puddle with better wetting action.

The wire diameter is 0.035 inches (0.9 mm), which is a versatile size suitable for welding thin sheet metal up to medium-thickness plate.

Yes, it is copper-coated. This coating improves electrical conductivity at the contact tip and aids in smooth feeding through the liner.

As an ER70S-6 class wire, the minimum tensile strength is typically 70,000 psi (480 MPa), suitable for most mild steel structural applications.
