ED561011 - Lincoln SuperArc L-56 ER70S-6 MIG Wire .045 44lb Spool

Premium Mild Steel MIG Wire for Industrial Fabrication

The Lincoln Electric SuperArc L-56 is the industry benchmark for copper-coated, mild steel MIG (GMAW) wire. Engineered with elevated levels of manganese and silicon deoxidizers, this ER70S-6 wire is specifically designed to combat porosity and defects when welding on base materials with light to moderate rust, oil, or mill scale. It is an excellent choice for general fabrication where surface preparation cannot always be perfect, ensuring sound welds with superior mechanical properties.

Superior Feedability and Arc Stability

One of the defining characteristics of the SuperArc L-56 is its exceptional feedability. Lincoln Electric utilizes a proprietary manufacturing process to ensure precise diameter control and a high-quality copper coating. This coating not only protects the wire from oxidation during storage but also enhances electrical conductivity at the contact tip. The result is a stable, consistent arc with minimal spatter, reducing post-weld cleanup time and increasing productivity. The wire feeds smoothly through standard MIG gun liners, minimizing bird-nesting and downtime.

Versatile Application Range

This 0.045-inch diameter wire is versatile enough to support multiple metal transfer modes, including short-circuiting, globular, axial spray, and pulsed spray transfer. This flexibility makes it suitable for a wide range of material thicknesses and welding positions. Whether used in automotive manufacturing, heavy equipment repair, or structural steel erection, the L-56 delivers excellent bead appearance with good toe-wetting action. The 44lb fiber spool provides a substantial volume of material for continuous operations, reducing the frequency of spool changes compared to smaller packages.

Quality and Compliance

Lincoln Electric maintains rigorous quality control standards. The SuperArc L-56 meets AWS A5.18/A5.18M specifications for ER70S-6 classification. It is formulated to provide consistent weld deposit chemistry, ensuring that your welds meet the required strength and ductility standards for critical applications.
