ED037005 - Lincoln SuperArc L-52 ER70S-2 MIG Wire .045 33lb Spool

Premium Industrial Grade ER70S-2 MIG Wire

Lincoln Electric's SuperArc® L-52® is a high-performance mild steel solid wire designed to meet the rigorous demands of industrial fabrication and manufacturing. Assigned the internal SKU ED037005, this product represents the pinnacle of Lincoln's wire manufacturing technology, specifically formulated for the ER70S-2 AWS classification. The "L-52" designation indicates a specialized chemical composition that goes beyond standard mild steel wires. It features a triple-deoxidized chemistry containing precise additions of Titanium (Ti), Zirconium (Zr), and Aluminum (Al), alongside the standard Manganese and Silicon deoxidizers. This robust chemical profile makes it the ideal choice for fabrication shops dealing with base materials that are not perfectly clean.

For procurement managers and industrial buyers, the reliability of the consumable is paramount to maintaining production schedules. The SuperArc L-52 is engineered with a premium copper coating that serves two critical functions: it protects the wire from oxidation during storage and ensures superior electrical conductivity at the contact tip. This results in fewer arc starts failures and reduced wear on consumable parts like tips and liners. The 33lb spool size is an optimal balance for medium-to-heavy duty cycles, reducing changeover downtime compared to smaller spools while remaining manageable for manual loading. This wire is particularly suited for structural steel applications, pipe welding, and general fabrication where surface preparation may be limited.

Lincoln Electric employs proprietary manufacturing processes to ensure that the wire diameter is consistent throughout the entire length of the spool. The .045-inch diameter is a versatile size, capable of high deposition rates in the flat and horizontal positions while still being manageable for out-of-position work when using short-circuit transfer or pulsed MIG modes. By choosing SuperArc L-52, facilities invest in a product that minimizes rework caused by porosity, thereby lowering the total cost of welding operations.
