ED026804 - Lincoln Outershield 71M .035 Flux-Core Wire 10lb Spool

High-Performance Gas-Shielded Flux-Cored Wire

The Lincoln Electric Outershield 71M is a premium mild steel flux-cored wire designed for industrial fabrication requiring consistency, speed, and mechanical integrity. This .035-inch diameter wire comes on a 10 lb spool, making it ideal for portable wire feeders and shop environments alike. It is engineered to provide excellent operating characteristics in all positions (excluding vertical down), offering versatility for complex structural assemblies.

Dual Gas Classification and AWS Compliance

One of the defining technical advantages of the Outershield 71M is its dual classification. It is formulated to perform exceptionally well with both 100% CO2 and a 75% Argon / 25% CO2 gas blend. This flexibility allows operators to optimize for cost (CO2) or arc characteristics (Argon mix) without changing consumables. The wire carries stringent AWS classifications, including E71T-9C-J and E71T-9M-J, indicating superior impact toughness properties. It has been Charpy V-Notch tested to -40°C (-40°F), ensuring reliable weld deposits in low-temperature service environments where brittle fracture is a concern.

Superior Feedability and Arc Physics

Lincoln Electric utilizes a proprietary rod-based manufacturing process for the Outershield 71M. Unlike strip-based wires that can suffer from seam irregularities or lack of stiffness, this wire exhibits industry-leading rigidity. This stiffness translates directly to improved feedability, reducing the risk of birdnesting in the feeder or liner friction in the gun cable. The arc physics are tuned for a spray-like transfer mode, which significantly reduces spatter levels compared to conventional flux-cored wires. This results in high travel speeds and reduced post-weld cleaning time, maximizing throughput in production settings.

Operational Efficiency

Beyond the metallurgical properties, the physical handling of the wire is designed for efficiency. The increased rigidity allows for a clean, easy manual break-off at the contact tip. Operators can simply snap the wire end by hand to ensure a clean stick-out for the next arc start, eliminating the repetitive need for side cutters and streamlining the restart process.
