Technical Features
- ER70S-6 classification with 70,000 PSI tensile strength delivers high-strength welds suitable for structural and fabrication work on ferrous metals.
- Elevated manganese and silicon content enables effective welding on rusty or dirty steel surfaces, reducing the need for extensive pre-weld surface preparation.
- Smooth bead profile minimizes post-weld grinding time, improving workflow efficiency on auto body and fabrication projects.
- 0.03 in. wire diameter suited for thinner gauge mild steel applications including auto body panels and light fabrication work.
- DCEP (Direct Current Electrode Positive) polarity ensures stable arc performance and consistent penetration with compatible MIG welding equipment.
- Yellow color-coded label allows for quick product identification and differentiation from other wire classifications in a multi-wire shop environment.
Applications
- Auto body repair and panel fabrication
- General fabrication on ferrous (mild steel) metals
- Welding on surfaces with light rust or mill scale
Note: This wire is not recommended for use on aluminum engines. Shielding gas (CO2 or Argon/CO2 blend) is required and is not included. California residents: see Prop 65 warnings at P65Warnings.ca.gov. Wash hands after use.
