Lincoln Outershield 71M .045 Flux-Core Wire 33lb Spool

Lincoln Electric ED030007 Outershield 71M .045" Wire

Take your welding projects to the next level with Lincoln Electric's Outershield 71M, a premium mild steel flux-cored wire designed for the serious welder. This .045-inch diameter wire comes on a standard 33 lb spool and is formulated for gas-shielded flux-cored arc welding (FCAW-G). It carries the AWS classification E71T-1C and E71T-1M, meaning it meets rigorous standards for tensile strength and impact toughness using either 100% CO2 or a 75/25 Argon/CO2 mix.

Welders appreciate the Outershield 71M for its "operator appeal." The arc is soft and stable, making it easy to control even for less experienced operators. The spatter generation is exceptionally low for a flux-cored wire, which keeps your nozzle cleaner for longer and protects your workpiece. One of the most practical features is the easy-break wire tip; you can often snap the wire by hand for a fresh restart without reaching for your side cutters every time. The slag coverage is complete but removes easily, often curling up on its own as the weld cools.

This wire is a workhorse for structural applications. Its fast-freezing slag supports the puddle well, allowing for high-speed travel in the flat position or controlled weaving in vertical-up applications. It offers deep penetration and excellent fusion, reducing the risk of cold lap. If you are fabricating trailers, repairing heavy machinery, or working on structural frames, the ED030007 Outershield 71M provides the mechanical integrity and ease of use required for professional results.

Performance Highlights:

• Smooth Arc: Stable transfer with minimal spatter.
• Easy Cleanup: Slag removes easily, often self-peeling.
• Dual Gas Use: Flexible gas options for shop versatility.
• Strong Welds: Meets AWS E71T-1/9 requirements for critical structures.
