ED500412 - Lincolnweld L-56 ER70S-6 1/16" MIG Wire - 60lb Coil

Premium ER70S-6 Solid MIG Wire for Heavy Fabrication

The Lincolnweld L-56 is Lincoln Electric's premier copper-coated mild steel solid wire, widely recognized as the industry standard for ER70S-6 classification. This specific SKU (ED500412) features a substantial 1/16-inch (1.6mm) diameter, making it particularly suitable for heavy-duty industrial applications, structural steel fabrication, and high-deposition welding scenarios. Packaged in a 60lb coil, it is designed for high-volume production environments where minimizing changeover time is critical.

Engineered with elevated levels of manganese and silicon, L-56 provides excellent deoxidizing properties. This chemical composition allows the wire to be more forgiving when welding over light rust, mill scale, and oil compared to standard ER70S-3 wires. The result is a sound weld deposit with minimal porosity and superior bead appearance. The wire's proprietary copper coating and manufacturing process ensure consistent diameter and cast, delivering exceptional feedability and extending contact tip life, even during extended welding sessions.

This 1/16" wire excels in axial spray transfer modes when used with high-argon shielding gas blends, offering deep penetration and high travel speeds. It is also compatible with 100% CO2 for broad penetration profiles. Whether used in semi-automatic or robotic setups, the Lincolnweld L-56 delivers reliable mechanical properties, including a typical tensile strength of 85-90 ksi and excellent Charpy V-Notch impact toughness.
