ED561117 - Lincoln SuperArc L-56 .035 MIG Wire 12.5lb Spool

Premium Mild Steel Solid Wire for Industrial Applications

The Lincoln Electric SuperArc L-56 is a premium copper-coated mild steel solid wire designed for the Gas Metal Arc Welding (GMAW) process. Classified as ER70S-6, this electrode is formulated with elevated levels of manganese and silicon. These chemical components act as powerful deoxidizers, enabling the wire to combat porosity and defects when welding on base materials with medium to heavy mill scale, oil, or surface contaminants. This makes it a superior choice for structural steel fabrication where surface preparation cannot always be perfect.

The 0.035-inch (0.9 mm) diameter offers versatility across a wide range of plate thicknesses and welding positions. The wire is manufactured with tight tolerances on diameter and cast, ensuring consistent feeding through long conduit liners and complex torch angles. The high-quality copper coating improves electrical pickup at the contact tip, reducing arc instability and extending the lifespan of consumables. This spool is packaged in a 12.5 lb (5.7 kg) format, typically suitable for intermediate wire feeders and portable industrial welding machines that utilize an 8-inch diameter spool hub.

SuperArc L-56 supports multiple metal transfer modes, including short-circuiting, globular, axial spray, and pulsed spray transfer. Its fluid puddle characteristics provide excellent toe-wetting, resulting in a flat bead profile that requires minimal post-weld grinding. Mechanical properties of the deposited weld metal meet or exceed AWS A5.18 requirements, providing reliable tensile strength and impact toughness for critical applications.
