The Miller 136683 is a specialized Teflon liner designed for the barrel assembly of Miller Spoolmatic 15, Spoolmatic 30A, and XR\/XR-M series push-pull guns. Engineered specifically for aluminum welding applications, this liner accommodates wire diameters ranging from .045 inches to 1\/16 inches (1.2 mm to 1.6 mm). The liner features a precise length of 6.812 inches, ensuring a perfect fit within the gun’s neck assembly to bridge the gap between the drive rolls and the contact tip.<\/p>\n
Aluminum wire is inherently soft and susceptible to deformation and shaving when pushed through standard steel liners. This product utilizes high-grade Teflon (PTFE) material, which offers an extremely low coefficient of friction. This material property is critical for maintaining laminar wire flow and preventing “bird-nesting” at the drive rolls. By minimizing drag, the liner reduces the load on the spool gun motor and ensures consistent arc characteristics.<\/p>\n
This package contains three (3) replacement liners, allowing for regular maintenance schedules in high-volume fabrication environments. Regular inspection and replacement of the barrel liner are recommended to prevent aluminum oxide buildup and mechanical wear from compromising weld quality. This is a genuine Miller Electric OEM part, ensuring dimensional accuracy and material compatibility with the specified welding systems.<\/p>\n","protected":false},"excerpt":{"rendered":"Technical Overview of Miller 136683 Teflon Liner The Miller 136683 is a specialized Teflon liner designed for the barrel assembly of Miller Spoolmatic 15, Spoolmatic 30A, and XR\/XR-M series push-pull guns.
