Lincoln Metalshield MC-110 .045" Metal Core Wire, 33 lb Spool

Superior Arc Control for High-Strength Steels

For welders tackling high-strength steel projects, the Lincoln Electric Metalshield MC-110 offers a superior welding experience that combines the ease of use of a MIG wire with the penetration and bead profile benefits of a flux-cored wire. This .045" metal cored wire is designed to produce smooth, high-quality welds on 110 ksi yield strength steels without the heavy slag burden associated with traditional flux-cored wires. The arc stability is exceptional, providing a crisp, consistent spray transfer that wets out smoothly at the toes of the weld, reducing the need for grinding to correct profile issues.

The Metalshield MC-110 is engineered to make your job easier. It features low spatter generation, which keeps your nozzle clean and reduces the amount of time spent scraping spatter off the base metal. The "enhanced silicon island management" means that the glass-like silica islands that form on the weld face are centralized and easy to pop off, leaving a clean surface for the next pass or for final inspection. This is a huge advantage when welding multi-pass joints on thick sections where inter-pass cleaning can slow you down.

Beyond playability, this wire gives you the confidence that your welds will hold up in extreme conditions. It is rated for excellent toughness even at temperatures as low as -60°F, making it the go-to choice for repairing heavy machinery, cranes, or offshore structures that face freezing environments. The H4 hydrogen rating adds another layer of security, ensuring your welds are resistant to cracking. Whether you are in the shop or fabricating heavy components, the Metalshield MC-110 delivers the professional results and high-strength performance required for top-tier welding jobs.

Welder-Centric Features:

• Smooth Arc: Stable spray transfer with minimal spatter.
• Easy Cleanup: Silicon islands remove easily; minimal post-weld grinding.
• Great Bead Profile: Wets out flat for excellent tie-in.
• Cold Toughness: Reliable impact properties for low-temp service.
