OVERVIEW

Technical Precision: ER70S-6 Solid Wire

The Super 6 ER70S-6 .030" (0.8mm) MIG Wire represents the industry standard for welding carbon and mild steels. Conforming to AWS A5.18 ER70S-6 specifications, this solid wire is engineered to provide high tensile strength and excellent impact toughness. The 0.030-inch diameter is a universal size, perfect for welding thin-gauge sheet metal in automotive applications (using short-circuit transfer) up to heavier structural plates (using spray transfer or globular transfer modes).

Metallurgical Advantages

The "S6" classification indicates a higher silicon and manganese content than S3 or S2 wires. This chemical balance provides superior deoxidizing capabilities, mitigating porosity caused by contaminants on the base material. The result is a sound, X-ray quality weld deposit with high ductility. The copper coating aids in smooth wire feeding and optimal current transfer, essential for automated or semi-automatic GMAW processes.

Operational Parameters

This wire is designed for use with DCEP (Direct Current Electrode Positive) polarity. It operates effectively with a variety of shielding gases:

  • 100% CO2: Provides deep penetration and broad fusion profiles, ideal for thicker sections but with slightly higher spatter.
  • 75% Argon / 25% CO2 (C25): Offers a stable arc, reduced spatter, and a visually appealing bead, preferred for general fabrication and sheet metal work.

The 20kg spool fits standard industrial wire feeders requiring a 2-inch spindle (adapter may be required depending on the hub design). It is suitable for all-position welding, making it a go-to solution for pipe welding, structural frames, and heavy equipment repair.

FAQ

You can use 100% CO2 for deeper penetration and lower cost, or a mix of 75% Argon / 25% CO2 (C25) for a smoother arc and less spatter.

Yes, the ER70S-6 classification means it has high levels of manganese and silicon deoxidizers, making it excellent for welding through light to moderate rust and mill scale.

This is a 20kg (approximately 44lb) spool. It is a standard industrial size typically used on larger MIG machines and wire feeders.

The wire diameter is 0.030 inches (0.8mm).

No, this is a solid wire that requires an external shielding gas bottle. It is not flux-cored.

This wire runs on DCEP (Direct Current Electrode Positive), also known as Reverse Polarity.

No, this is a mild steel wire. You need aluminum wire and pure argon gas for welding aluminum.

Yes, it features a high-quality copper coating to prevent rust on the wire and improve electrical contact.
