ED037003 - Lincoln SuperArc L-52 ER70S-2 .035 MIG Wire 33lb Spool

Premium Triple Deoxidized MIG Wire for Industrial Fabrication

The Lincoln Electric SuperArc L-52 is a high-performance ER70S-2 solid MIG welding wire designed for the most demanding industrial environments. Engineered with a triple deoxidized chemistry containing specific additions of Titanium, Zirconium, and Aluminum, this wire excels in applications where the base metal condition is less than ideal. Whether you are dealing with heavy mill scale, rust, oil, or paint, the L-52 formulation acts as a powerful scavenger of oxygen and nitrogen, significantly reducing the risk of porosity and ensuring sound, defect-free welds. This makes it the preferred choice for pipe welding, structural steel fabrication, and maintenance repair operations where surface preparation cannot always be perfect.

Beyond its chemical superiority, the SuperArc L-52 features Lincoln's proprietary MicroGuard surface treatment and a high-quality copper coating. This manufacturing precision guarantees exceptional feedability, minimizing friction within the gun liner and ensuring consistent electrical contact at the tip. For automated or robotic systems, this translates to reduced downtime and higher productivity. The 0.035-inch diameter is versatile enough for positional welding on thin-to-medium gauge materials while providing enough deposition for thicker sections when running in spray transfer mode.

The mechanical properties of the weld deposit meet stringent AWS A5.18 standards, offering excellent tensile strength and ductility. The wire produces a fluid puddle with excellent wetting action, resulting in a flat bead profile that requires minimal post-weld grinding. Packaged in a durable 33lb spool, the ED037003 fits standard industrial wire feeders, ensuring you have the capacity needed for long production runs. Trust Lincoln Electric's legacy of quality to deliver a consumable that enhances both the efficiency of your process and the integrity of your final product.
