ED030009 - Lincoln Outershield 71M 1/16" Flux-Cored Wire 33lb Spool

Technical Overview of Lincoln Outershield 71M

The Lincoln Electric Outershield 71M (SKU: ED030009) is a premium mild steel, flux-cored wire designed for gas-shielded arc welding (FCAW-G). This 1/16-inch diameter wire is supplied on a 33-pound spool, making it an industrial standard for heavy-duty fabrication environments. It is engineered to meet AWS A5.20 specifications, carrying classifications E71T-1C-H8, E71T-1M-H8, E71T-9C-H8, and E71T-9M-H8. This versatility allows the wire to be used effectively with either 100% CO2 shielding gas or a blend of 75-80% Argon with the balance CO2, providing fabrication shops with flexibility depending on their available gas supply and desired arc characteristics.

Mechanically, Outershield 71M delivers robust weld deposits. When used with CO2, it typically yields a tensile strength of 88-93 ksi and a yield strength of 75-82 ksi, with Charpy V-Notch impact toughness values exceeding 20 ft-lbf at -20°F (-29°C). The wire's formulation ensures low hydrogen levels (H8), reducing the risk of hydrogen-induced cracking in critical structural applications. The 1/16-inch diameter is particularly suited for higher deposition rates in flat and horizontal positions while maintaining controllability in out-of-position work due to its fast-freezing slag system.

This consumable is ideal for general purpose fabrication where efficiency and weld quality are paramount. It excels in applications involving ASTM A36, A572 Grade 50, and other common structural steels. The spool packaging is designed for standard industrial wire feeders, ensuring smooth feeding and consistent electrical contact. By standardizing on Outershield 71M, facilities can streamline their inventory while covering a broad range of welding procedure specifications (WPS).
