ED033910 - Lincoln Metalshield MC-110 .045" Metal Core Wire, 33 lb Spool

High-Performance Low Alloy Metal Core Wire

The Lincoln Electric Metalshield MC-110 is a premium gas-shielded metal cored tubular wire designed for the welding of high-strength low alloy steels. Engineered to meet the rigorous demands of heavy industrial fabrication, this wire (SKU: ED033910) delivers a minimum tensile strength of 760 MPa (110 ksi), making it an essential consumable for structural projects requiring superior mechanical integrity. The wire is formulated with advanced deoxidizing agents that significantly reduce pre- and post-weld cleaning times, thereby optimizing production throughput in manufacturing environments.

One of the standout technical characteristics of the Metalshield MC-110 is its H4 diffusible hydrogen designation. In high-strength steel welding, hydrogen-induced cracking is a critical concern; the H4 rating ensures extremely low levels of diffusible hydrogen, providing confidence in the weld's resistance to cold cracking. Furthermore, the wire exhibits exceptional low-temperature impact properties, capable of exceeding 40 J (30 ft·lbf) at -51°C (-60°F). This makes it particularly suitable for equipment and structures operating in harsh, sub-zero environments where material toughness is paramount.

Operational efficiency is further enhanced by Lincoln Electric's proprietary manufacturing technology, which ensures consistent wire feeding and arc stability. The enhanced silicon island management system aggregates silica into manageable islands that are easily removed, reducing downtime associated with inter-pass cleaning. Packaged in a durable 33 lb plastic spool, this .045-inch diameter wire is compatible with standard industrial wire feeders and is optimized for use with argon-based shielding gas mixtures (M20 class), providing a smooth spray transfer mode that increases deposition rates compared to solid wires.

Key Industrial Benefits:

• High Strength: Meets 110 ksi tensile requirements for critical load-bearing structures.
• Productivity: Metal core design allows for higher travel speeds and deposition rates.
• Reliability: Low hydrogen levels (H4) minimize the risk of weld failure.
• Versatility: Excellent performance in flat and horizontal positions for heavy fabrication.
