Liner, .035-.045" Wire, 16.5 ft | MIL202890

Ensure smooth, consistent wire delivery and high-quality welds with the Miller Electric 202890 Roughneck MIG Gun Liner. Specifically designed to handle the intense heat of industrial welding (rated for 350A to 600A), this liner effectively eliminates common feeding issues like wire drag, erratic arcs, and "birdnesting." Its zinc-plated monocoil steel construction provides a durable, low-friction conduit that resists corrosion and kinking, even when your gun cable is looped or bent. By maintaining a clean feed path, this liner helps extend the life of your contact tips and wire feeder motor, making it a cost-effective essential for heavy-duty fabrication and structural steel projects.

• Industrial Wire Compatibility: Optimized for .035" and .045" (0.9–1.2 mm) welding wires, the most common sizes for medium-to-heavy fabrication.
• Heavy-Duty Monocoil Design: Constructed from round wound steel to provide a rugged, kink-resistant path for the wire, ensuring consistent arc stability.
• Extended 16.5-Foot Length: Sized to fit 15-foot cable assemblies with an extra 1.5 feet to allow for a precise "trim-to-fit" installation at the gas diffuser.
• High-Amperage Performance: Built to withstand the rigorous demands of 350–600 amp applications without deforming or losing its low-friction properties.
• Direct Roughneck Fit: Guaranteed compatibility with Miller Roughneck C-Series guns (models like C-3015, C-4015, and C-5015) for a hassle-free replacement.
