Lincoln Metalshield MC-70 XLS .052 Metal-Cored Wire 750lb Drum

High-Productivity Metalshield MC-70 XLS for Automation

Lincoln Electric's Metalshield® MC-70 XLS™ represents the pinnacle of metal-cored wire technology for mild steel fabrication. This .052" diameter wire, supplied in a bulk 750lb Accu-Trak® drum, is designed to meet the rigorous demands of modern manufacturing, particularly in sectors like automotive and heavy fabrication. The "XLS" designation highlights its standout feature: Extra Low Silicon islands. In traditional welding processes, silicon deposits often form glassy islands on the weld bead that must be mechanically removed before painting or e-coating. The MC-70 XLS™ chemistry minimizes these deposits, leaving a clean, smooth toe line that often requires little to no post-weld preparation.

The 750lb Accu-Trak® drum is a strategic asset for facilities focused on continuous improvement and lean manufacturing. This bulk packaging system is engineered to deliver wire straight and tension-free, preventing the "helix" or "cast" issues that can cause wandering arcs in robotic applications. By utilizing a larger payoff pack, welders and machine operators spend less time swapping out spools and more time welding. This is crucial for maintaining high duty cycles in automated cells where every minute of downtime impacts the bottom line.

Beyond its packaging and surface finish benefits, the Metalshield® MC-70 XLS™ is a performance powerhouse. It operates with a smooth spray arc that provides deep penetration and excellent sidewall fusion, reducing the risk of cold lap defects. The metal-cored design allows for higher current densities than solid wire, resulting in faster travel speeds and increased deposition rates. This efficiency makes it a superior alternative to E70S-6 solid wires in many flat and horizontal fillet weld applications.

Welders will appreciate the soft, stable arc and the reduced spatter generation, which keeps nozzles clean and extends the life of consumables. The wire is designed for use with Argon/CO2 blends, optimizing the spray transfer mode for maximum stability. Whether you are welding chassis frames, suspension components, or general structural assemblies, the Lincoln Metalshield® MC-70 XLS™ delivers the consistency and quality required for world-class fabrication standards.
