Product Description
The Lincoln Primacore LW-71 Flux Cored Welding Wire (1.6mm) is a gas-shielded, rutile-based, general-purpose flux cored wire engineered for all-position welding of mild and medium-strength carbon-manganese (C-Mn) steels. Built for fabricators, contractors, and structural welders who need reliable, high-quality welds without compromising on speed or control, this micro-alloyed wire delivers a smooth arc, low spatter, and excellent bead appearance across a wide range of industrial applications.
Designed to run with 100% CO2 shielding gas, LW-71 offers strong penetration and very good notch toughness, making it a dependable choice for structural steel fabrication, general engineering, construction, shipbuilding, and heavy equipment repair. Its rutile flux formulation produces a stable arc with easy slag removal, helping welders maintain productivity on both flat and out-of-position joints.
At 1.6mm diameter, this wire is well suited to medium-to-heavy gauge steel work where higher deposition rates and travel speeds are needed, without sacrificing weld quality or operator control.
Key Features
- Flux Cored (FCAW-G) construction – gas-shielded for stable arc performance and reduced spatter

- Rutile, micro-alloyed formulation – smooth arc characteristics with easy slag detachment
- All-position capable – suitable for flat, horizontal, vertical, and overhead welding
- Very good notch toughness – reliable performance in structural and load-bearing applications
- Recommended shielding gas: 100% CO2
- AWS classification: A5.20 E71T-1C (also referenced to AS/NZS 17632R – T49 3 T1-1 CAK)
Recommended Applications
- Structural steel fabrication
- General engineering and construction
- Heavy equipment and machinery repair
- Mild to medium-strength C-Mn steel welding
- Workshop and industrial MIG/flux-cored welding setups requiring consistent, high-deposition welds
