ER70S-6, MIG Welding Wire, Mild Steel, .024 in Diameter x 2 - FORNEY INDUSTRIES

Part #: 42290

The FORNEY INDUSTRIES 42290 ER70S-6 MIG Welding Wire is engineered for professional technicians and mechanics tackling a wide range of mild steel welding tasks. This premium mild steel wire delivers consistent, high-quality welds, even when working with surfaces that are less than ideally clean. Its advanced formulation ensures reliable performance in diverse automotive and industrial applications.

Key Features

  • Superior Deoxidizing Properties: Contains high levels of manganese and silicon, providing excellent deoxidizing power for welding on mild steel, carbon steel, and even moderately rusty, dirty, or scaled surfaces.
  • Smooth Arc and Bead Appearance: Designed to produce a stable arc, minimizing spatter and creating a smooth, flat weld bead that often requires less post-weld grinding.
  • High Tensile Strength: Achieves a minimum tensile strength of 70,000 psi, ensuring strong, ductile, and dependable weld joints.
  • Enhanced Weld Pool Fluidity: The higher silicon content increases the fluidity of the weld pool, contributing to a smoother bead appearance and allowing for potentially faster travel speeds.
  • Versatile Shielding Gas Compatibility: Compatible with various shielding gases, including 75/25% Argon/CO2, 90/10% Argon, and 100% CO2, offering flexibility for different welding environments.
  • Precision and Control: The .024 inch diameter wire is ideal for precision welding, providing excellent control of the weld puddle, especially on thinner materials.

Applications

This ER70S-6 welding wire is an excellent choice for general fabrication and repair across various industries. It is particularly well-suited for automotive body repair, chassis work, and the fabrication of light-gauge materials. Professionals in construction, farm equipment maintenance, and general shop fabrication will find it highly effective for butt and fillet welding of carbon steel sheet and plate. It excels in single or multi-pass welding on mild and carbon steels.
