ED037281 - Lincoln Metalshield MC-70 XLS .045 Metal Core Wire 750lb Drum

Advanced Metal-Cored Wire for Automation

The Lincoln Electric Metalshield® MC-70 XLS™ represents a significant leap forward in metal-cored wire technology, specifically engineered to address the productivity bottlenecks associated with post-weld cleaning. This .045-inch diameter wire, supplied in a substantial 750 lb drum, is designed for high-volume industrial environments where efficiency and throughput are paramount. The "XLS" designation highlights its specialized formulation intended to produce an exceptionally clean weld surface with minimal silicon islands. In traditional metal-cored welding, silicon deposits often require mechanical removal before painting or coating; the MC-70 XLS mitigates this, often allowing parts to move directly to the paint line, thereby streamlining the entire fabrication workflow.

From a metallurgical perspective, this wire meets AWS E70C-6M classifications, offering robust mechanical properties suitable for mild steel applications. It is optimized for use with Argon/CO2 shielding gas blends, which helps stabilize the arc and reduce spatter. The metal-cored construction allows for higher current densities and faster travel speeds compared to solid wires, resulting in superior deposition rates. This makes it an ideal choice for industries such as automotive manufacturing, heavy equipment fabrication, and structural steelworks where cycle times are critical.

The 750 lb drum packaging is a strategic feature for facilities utilizing robotic cells or hard automation. By significantly increasing the amount of wire available before a spool change is required, downtime is drastically reduced. This bulk packaging ensures a continuous, uninterrupted feed, which is essential for maintaining the consistency and quality demanded by automated systems. The wire is precision-wound to ensure tangle-free feeding, further enhancing the reliability of the welding operation. When integrated into a high-production environment, the Metalshield MC-70 XLS provides a tangible return on investment through reduced labor costs associated with cleanup and changeovers.

Furthermore, the arc characteristics of the MC-70 XLS are tuned for stability and wetting. Good wetting action ensures smooth tie-in at the toes of the weld, reducing stress concentrations and improving the fatigue life of the joint. The reduction in spatter not only keeps the workpiece clean but also reduces the maintenance frequency required for the welding gun nozzle and contact tip. For industrial procurement specialists seeking a consumable that balances high-speed performance with superior surface finish quality, the Lincoln Electric Metalshield MC-70 XLS is a premier solution.
