YESWELDER ER70S-6 .035 in Carbon Steel MIG Wire | 44 lb Spool

Overview

The YESWELDER ER70S-6 MIG wire is a copper-coated carbon steel solid wire designed for reliable single or multiple pass welding. With a diameter of .035 inch (0.9 mm) and a robust 44 lb spool, this wire is built to feed smoothly through common MIG welding setups, helping you tackle a wide range of jobs with consistency.

Key benefits at a glance

• Shielding gas compatibility that accommodates 100% CO2 or a mixture of 80% Ar and 20% CO2, allowing you to tailor the gas to your material and machine.
• High performance thanks to manganese and silicon deoxidizers, which support higher welding currents with 100% CO2 and contribute to a smoother bead with less post-weld cleanup.
• Versatility across many applications, from sheet metal to structural components, tanks, automotive repairs, and general shop projects—even when fit-up is imperfect or metal is rusty or oily.
• Durable, anti-fragile ABS spool design protects the wire during transportation and in the workflow, helping you reduce downtime from spool damage.
• Specifically sized for practical use: weight 44 lbs and diameter .035, making it suitable for mid to heavy gauge welding tasks.

What you can weld

• Sheet metal, structural components, and farm equipment frames where steady current and reliable deposition matter.
• Automotive body repairs, tanks, and light steel fabrication where a smooth bead is desirable and post-weld cleanup is a plus.
• General shop work on steel with challenging fit-up or surface contaminants, where a forgiving wire can help maintain process stability.

When selecting your shielding gas, ensure compatibility with your welding machine and desired finish. The ER70S-6 wire supports both 100% CO2 and mixed gas environments, giving you flexibility across different projects and environments. While results can vary based on process settings and joint configuration, this wire is designed to help you achieve dependable deposition, controlled penetration, and cleaner welds with fewer rework iterations.
