ED561007 - Lincoln SuperArc L-56 .045 MIG Wire 44lb Spool

Premium Mild Steel MIG Wire for Industrial Fabrication

The Lincoln Electric SuperArc L-56 (ED561007) is a premium copper-coated mild steel solid wire designed for the Gas Metal Arc Welding (GMAW) process. Classified as ER70S-6, this .045-inch diameter wire is engineered with elevated levels of manganese and silicon. These deoxidizers make the L-56 exceptionally capable of handling base materials with medium to heavy mill scale, rust, or oil, ensuring sound welds even in less-than-perfect surface conditions.

Packaged on a 44lb fibre spool, this product is optimized for industrial environments requiring consistent feedability and arc stability. The high-quality copper coating improves electrical conductivity and reduces friction in the liner, significantly extending contact tip life and minimizing downtime. The wire supports a wide range of metal transfer modes, including short-circuiting, globular, axial spray, and pulsed spray transfer, making it a versatile choice for various welding positions and parameters.

Ideally suited for general fabrication, automotive assembly, and structural steel work, the SuperArc L-56 delivers excellent toe-wetting action, resulting in a flat, smooth bead profile that requires minimal post-weld grinding. Its consistent chemistry and diameter control ensure repeatable performance, critical for automated or high-volume manual welding operations.
