ED561006 - Lincoln SuperArc L-56 ER70S-6 MIG Wire .035 44lb Spool

Premium Mild Steel Solid Wire for Industrial Fabrication

The Lincoln Electric SuperArc L-56 is a premium copper-coated mild steel solid wire designed for the Gas Metal Arc Welding (GMAW) process. Carrying the AWS classification ER70S-6, this wire is formulated with elevated levels of manganese and silicon. These chemical elements act as powerful deoxidizers, making the L-56 exceptionally capable of handling base metals with medium to heavy mill scale, rust, or oil. This chemical composition ensures that porosity is minimized even when welding conditions are less than ideal, providing a sound deposit with excellent mechanical properties.

One of the defining characteristics of the SuperArc L-56 is its superior toe-wetting action. The molten weld pool is highly fluid, allowing it to wash into the sides of the joint smoothly. This results in a flat, aesthetically pleasing bead profile that requires minimal post-weld grinding or finishing. For industrial applications where bead appearance and structural integrity are paramount, L-56 stands out as a reliable choice. The wire is engineered to support a wide range of metal transfer modes, including short-circuiting, globular, axial spray, and pulsed spray transfer, making it versatile across different welding parameters and positions.

Lincoln Electric employs advanced manufacturing techniques to ensure the copper coating on the L-56 is uniform and tightly adherent. This coating serves two critical functions: it enhances electrical conductivity for a stable arc, and it reduces friction within the liner and contact tip. The result is extended consumable life and reduced downtime for maintenance. The 44lb fibre spool packaging is designed for high-volume industrial environments, offering a substantial amount of material to minimize changeovers while being environmentally easier to dispose of than traditional plastic spools. This product is ideal for general fabrication, automotive assembly, and heavy equipment manufacturing where consistent feedability and arc performance are non-negotiable.
