ED030550 - Lincoln Metalshield MC-6 .052 Metal Core Wire 60lb Coil

High-Efficiency Metal Core Welding Wire

The Lincoln Electric Metalshield MC-6 .052" Metal Core Wire (SKU: ED030550) is a premium choice for industrial fabricators seeking to maximize productivity and weld quality. As a metal-cored wire, the MC-6 combines the high deposition rates of flux-cored wires with the high efficiency and low slag generation of solid MIG wires. This 60lb coil format is designed for high-volume production environments, reducing downtime associated with frequent spool changes.

Optimized for Automation and Speed

Metalshield MC-6 is engineered specifically to excel in robotic and hard automation applications where travel speed and bead consistency are critical. The wire formulation promotes exceptional wetting action, allowing the weld puddle to flow out smoothly even at high travel speeds. This characteristic helps eliminate cold lap and undercutting, common issues in high-speed manufacturing. Furthermore, the MC-6 produces minimal silicon islands, which is a significant advantage for multi-pass welding operations; often, the weld surface is clean enough to paint or weld over without intermediate power brushing.

Superior Arc Characteristics

Welders utilizing the MC-6 will appreciate its stable, smooth arc and low spatter levels when used with Argon/CO2 shielding gas blends (typically 75/25 or 90/10). The wire meets AWS E70C-6M H4 classification, ensuring high tensile strength and low diffusible hydrogen levels, which minimizes the risk of hydrogen-induced cracking in critical structural applications. Its ability to handle higher amperages than solid wires of the same diameter means deeper penetration and faster completion of heavy weldments.

Application Versatility

While optimized for the automotive and heavy equipment industries, this .052" diameter wire is versatile enough for general structural fabrication, railcar manufacturing, and shipbuilding. It handles mill scale and mild surface contaminants better than solid wires, thanks to the deoxidizers present in the metal powder core. For shops looking to upgrade from solid wire to increase throughput without the slag burden of flux-core, the Lincoln Metalshield MC-6 is the ideal solution.
