ED561008 - Lincoln SuperArc L-56 .052 MIG Wire 44lb Spool

Premium Mild Steel MIG Wire for Industrial Fabrication

The Lincoln Electric SuperArc® L-56® .052" MIG Wire (SKU: ED561008) represents the pinnacle of copper-coated solid wire technology for mild steel applications. Classified as an AWS ER70S-6, this wire is engineered with elevated levels of manganese and silicon deoxidizers. These chemical additions allow the wire to tolerate moderate to high levels of mill scale, rust, and oil on the base material, making it an essential consumable for structural fabrication, heavy equipment manufacturing, and general maintenance where perfect surface preparation is not always feasible.

Lincoln Electric utilizes proprietary manufacturing processes to ensure the SuperArc L-56 delivers exceptional feedability. The copper coating is applied with precision to enhance electrical conductivity and extend contact tip life, while the wire is wound with a consistent cast and helix. This attention to geometry prevents tangling and ensures smooth feeding through long conduit runs, making it highly suitable for both manual and robotic welding cells. The 44lb (20kg) fibre spool is designed to fit standard industrial wire feeders, reducing changeover downtime in high-volume production environments.

Technical specifications indicate that this .052" diameter wire is optimal for welding thicker plate materials, offering higher deposition rates than .035" or .045" alternatives. It operates effectively with 100% CO2 shielding gas for deep penetration or Argon/CO2 blends for a smoother arc and reduced spatter. The resulting weld deposits exhibit excellent mechanical properties, including high tensile strength and impact toughness, meeting the rigorous demands of automotive and infrastructure projects.

Key Industrial Benefits

• Contaminant Tolerance: High deoxidizer content neutralizes surface impurities, reducing porosity defects.
• Feedability: MicroGuard® surface treatment and precision winding minimize friction and liner wear.
• Versatility: Suitable for all-position welding (with appropriate transfer modes) on a wide range of mild steel grades.
