ED022659 - Lincoln Outershield 71M .045" Gas-Shielded Flux-Core Wire 25lb

Industrial Grade Performance with Lincoln Outershield 71M

The Lincoln Electric Outershield® 71M is a premium gas-shielded flux-cored wire designed for the rigorous demands of heavy fabrication and structural steel welding. Identified by the internal SKU ED022659, this .045-inch diameter wire comes in a 25 lb spool and is engineered to deliver consistent, high-quality welds across a variety of applications. It is dual classified, meeting AWS specifications for both 100% CO2 and a 75% Argon / 25% CO2 shielding gas blend, providing shops with the flexibility to optimize their process based on available gas supplies and desired arc characteristics.

One of the defining technical advantages of the Outershield 71M is its manufacturing process. Unlike strip-based wires, this product utilizes a rod-based manufacturing technique that imparts industry-leading stiffness and column strength to the wire. This structural integrity translates directly to superior feedability, significantly reducing the risk of buckling or bird-nesting in the gun liner, even over long distances or through tortuous cable paths. The wire is formulated to meet stringent mechanical properties, including Charpy V-Notch impact toughness tested down to -40°C (-40°F), making it suitable for critical applications requiring ductility at low temperatures.

The chemical composition and flux formulation are balanced to produce a spray-like transfer mode that is smooth and stable. This results in a flat bead profile with excellent wash-in, minimizing the risk of cold lap or lack of fusion. The slag system is designed for easy removal, often peeling off by itself, which reduces post-weld cleaning time. With classifications including E71T-9C-J and E71T-9M-J, this wire is a robust solution for general fabrication, shipbuilding, and heavy equipment manufacturing where reliability and efficiency are paramount.
