KP3543-35116-15 - Lincoln KP3543-35116-15 Aluminum Liner 15ft for Magnum PRO AL

Precision Aluminum Feeding with Lincoln Electric

The Lincoln Electric KP3543-35116-15 Aluminum Push-Pull MIG Gun Liner is a critical component designed to ensure the smooth and reliable delivery of aluminum welding wire. Specifically engineered for use with Magnum® PRO AL Pistol Grip push-pull MIG guns, this liner addresses the unique challenges associated with feeding soft aluminum alloys. Unlike steel wire, which has high column strength, aluminum wire is pliable and prone to buckling, bird-nesting, and shaving if not guided correctly. This genuine Lincoln Electric liner provides a low-friction path that protects the wire integrity from the drive rolls to the contact tip.

With a length of 15 feet, this liner is perfectly sized for standard push-pull gun cable assemblies, allowing welders to maintain a comfortable distance from the power source while working on large fabrications. The liner's internal geometry is optimized for wire diameters ranging from .035 inches to 1/16 inches (0.9 mm to 1.6 mm), covering the most common sizes used in industrial aluminum welding applications. Proper liner maintenance is essential for consistent arc performance; a worn or clogged liner can lead to erratic feeding, burn-backs, and downtime. Replacing your liner with this OEM part restores the gun's performance to factory standards.

The push-pull system is the industry standard for feeding aluminum over distances, and the liner is the backbone of this system. The KP3543-35116-15 is constructed from high-quality materials that resist kinking while offering the flexibility needed for maneuvering the gun in tight spaces. Whether you are welding trailer bodies, boat hulls, or aluminum signage, this liner ensures that your filler metal arrives at the weld pool without deformation or contamination. It is compatible with the specific drive roll configurations found in the Magnum PRO AL series, ensuring a seamless fit and hassle-free installation.

Key Benefits:

• Optimized for Aluminum: Reduces friction and prevents wire shaving common with soft wires.
• Versatile Wire Range: Handles both thin gauge .035" and thicker 1/16" wires effectively.
• OEM Quality: Guaranteed fit and performance with Lincoln Magnum PRO AL systems.
• Durable Construction: Resists wear and kinking for a longer service life in industrial environments.
