Lincoln Outershield® 71M 0.045 in Flux-Cored Welding Wire is a proven, all-around E71T-1 performer engineered for excellent feedability, smooth arc stability, and high productivity across a wide range of fabrication environments. Built for efficiency on the jobsite, this wire eliminates the need for side cutters—simply break the wire by hand to restart and keep welding. With high travel speeds, spray-like metal transfer, and reliable toughness, Outershield® 71M is a trusted choice for structural, marine, and heavy fabrication applications.
- Dual-classified for use with both 100% CO₂ and 75% Argon / 25% CO₂ mixed shielding gases
- Charpy V-Notch impact toughness tested down to -40°C (-40°F) for demanding structural and cold-weather applications
- High travel speeds increase deposition efficiency and overall welding productivity
- Spray-like metal transfer with minimal spatter for cleaner welds and reduced post-weld cleanup
- Rod-based manufacturing delivers industry-leading wire stiffness and consistent feedability
- Increased wire rigidity allows easy manual break-off without side cutters
