LNXS2615-35 - Lincoln Electric SuperArc L-56 .035" MIG Wire (12.5 lb Spool)

Premium Mild Steel MIG Wire for Professional Fabrication

The Lincoln Electric SuperArc® L-56® (SKU: LNXS2615-35) is a premium copper-coated solid wire designed for the Gas Metal Arc Welding (GMAW) process. This 12.5 lb spool features a 0.035-inch diameter, making it an incredibly versatile choice for a wide range of industrial and light-industrial applications. As an AWS ER70S-6 classified wire, the L-56 is formulated with higher levels of manganese and silicon compared to standard S-3 wires. These added deoxidizers allow the wire to handle surface contaminants effectively, making it the go-to choice for welding on base metals that may have medium-to-heavy mill scale, light rust, or oil.

Lincoln Electric employs strict manufacturing tolerances to ensure consistent wire diameter, cast, and helix. This attention to detail results in a wire that feeds smoothly through MIG gun liners and contact tips, reducing downtime caused by bird-nesting or burn-backs. The high-quality copper coating aids in electrical conductivity and protects the wire from corrosion during storage, ensuring that the wire performs as expected even after sitting on the shelf. Whether used with 100% CO2 for deeper penetration or an Argon/CO2 blend for a smoother arc and reduced spatter, the SuperArc L-56 delivers professional results.

This 12.5 lb spool size is ideal for medium-duty welding machines and portable wire feeders commonly found in automotive repair shops, maintenance departments, and fabrication facilities. It strikes a balance between portability and run-time, reducing the frequency of spool changes compared to smaller 2 lb spools while fitting machines that cannot accommodate large 33 lb or 44 lb packages. Trust Lincoln Electric's legacy of quality to provide a stable arc, excellent bead appearance, and reliable mechanical properties for your mild steel welding projects.
