ED037105 - Lincoln Metalshield MC-70 XLS .045 Metal Core Wire 33lb

Superior Arc Performance with Metalshield MC-70 XLS

For professional welders who demand control, consistency, and a premium bead appearance, the Lincoln Electric Metalshield® MC-70 XLS™ sets a new standard in metal-cored welding wires. This .045-inch wire is designed to deliver a smooth, stable arc with exceptionally low spatter levels, making it a pleasure to run even during long shifts. One of the standout characteristics of the MC-70 XLS is its best-in-class edge wetting. The weld puddle flows out smoothly to the toes of the weld, creating a flat, professional-looking bead profile that blends seamlessly with the base metal. This superior wetting action not only improves aesthetics but also helps reduce stress concentrations at the weld toes.

Real-world welding conditions are rarely perfect, and the Metalshield MC-70 XLS is built to handle the challenges of the shop floor. It exhibits excellent tolerance for welding over mild rust and mill scale, allowing you to lay down sound welds without porosity issues, even when surface preparation isn't perfect. The "XLS" in the name stands for the wire's advanced formulation that results in minimal silicon islands. For the welder, this means less time spent with a chipping hammer or grinder after the hood goes up, and a cleaner finished product that you can be proud of.

This wire is classified as E70C-6M-H4, indicating it is a metal-cored electrode intended for use with mixed shielding gases (typically Argon/CO2 blends). The "H4" designation is particularly important for structural work, as it signifies very low levels of diffusible hydrogen, providing confidence when welding on thicker sections or restrained joints where cracking could be a concern. Packaged in a convenient 33 lb spool, it is ready to load into your feeder for general fabrication, structural steel erection, or heavy equipment repair.

Welder-Centric Features:

• Clean Welds: Almost no silicon islands to chip off.
• Forgiving Arc: Handles scale and rust while maintaining stability.
• Premium Appearance: Excellent wash-in and bead contour.
