6910-0506V - Vanguard ER70S-6 Solid Mild Steel MIG Welding Wire - 0.023 in - 5kg Spool

Technical Overview of Vanguard ER70S-6 Solid MIG Wire

The Vanguard ER70S-6 0.023" (0.6mm) Solid MIG Welding Wire is a premium general-purpose filler metal designed for the Gas Metal Arc Welding (GMAW) of mild and low-alloy steels. Formulated to meet AWS A5.18 specifications, this wire features a chemical composition rich in manganese and silicon. These deoxidizers act as powerful cleaning agents during the welding process, scavenging oxygen and impurities from the weld pool. This makes the wire particularly effective when welding on base materials that exhibit light to moderate rust, mill scale, or oil, ensuring sound, porosity-free deposits.

This 5kg (11lb) spool is precision-engineered to provide consistent feedability, a critical factor in maintaining a stable arc and preventing burn-back or bird-nesting in the drive rolls. The wire surface is copper-coated, which serves dual purposes: it enhances electrical conductivity at the contact tip for efficient energy transfer and protects the wire from oxidation during storage. The 0.023-inch diameter is the industry standard for low-amperage applications, allowing for precise control over heat input.

Mechanical properties of the deposited weld metal typically exceed 70,000 PSI tensile strength, providing structural integrity suitable for a wide range of industrial codes. The wire is designed for use with Direct Current Electrode Positive (DCEP) polarity and operates effectively with both 100% CO2 shielding gas (for deeper penetration) and Argon/CO2 blends (for reduced spatter and better bead appearance). It is an essential consumable for fabrication environments requiring versatility and reliability.
