ED032903 - Lincoln SuperArc L-50 ER70S-3 1/16" MIG Wire 500lb Drum

Lincoln Electric SuperArc® L-50®: The Standard for ER70S-3 Performance

Lincoln Electric's SuperArc® L-50® (ER70S-3) is a low-alloy steel MIG wire designed to deliver superior arc stability and wetting characteristics. This 1/16" (1.6 mm) variant is particularly suited for heavy fabrication where higher deposition rates are required. The wire chemistry is carefully balanced with moderate levels of manganese and silicon, making it an excellent deoxidizer for base materials that are clean or have only light mill scale.

One of the standout features of the SuperArc® L-50® is its versatility across different transfer modes. It supports short-circuiting, globular, axial spray, and pulsed spray transfer, giving welding engineers the flexibility to optimize parameters for specific joint configurations and positions. The premium copper coating is applied using Lincoln's proprietary manufacturing processes, ensuring excellent adhesion and minimal flaking. This coating promotes superior current transfer at the contact tip, reducing arc wander and extending tip life.

The 500 lb Accu-Pak® Box is an advanced packaging solution designed to eliminate wire flip and tangling. For robotic and hard automation setups, this means reliable seam tracking and consistent weld deposition. The wire's mechanical properties are optimized for 50,000 psi yield strength steels, providing ductile and sound welds. By choosing SuperArc® L-50®, shops can achieve high-quality welds with minimal spatter and post-weld cleanup.
