The DF Machine Specialties 12402 is a 10-foot nylon MIG welding wire liner specifically engineered for 1/16" (1.6mm) aluminum and Inconel wire. It is designed for use in automatic, robotic, and high-amperage water-cooled welding environments to facilitate smooth wire feeding while protecting the integrity of soft wire surfaces.
Features
Friction Reduction: Nylon material minimizes drag coefficient for aluminum wire travel
Surface Protection: Prevents scratching and shaving of soft aluminum wire surfaces
Contamination Control: Eliminates aluminum dust and shavings that contaminate weld pools
Feed Stability: Maintains columnar strength to prevent wire wandering or drifting
Flexibility: Supports complex torch movements and tight bends without kinking
Maintenance: Can be cleaned with compressed air to remove debris buildup
Installation: Designed to be cut flush with gas nozzle and adjusted for contact tip length
Secure Fit: Compatible with Allen set screw locking to prevent backward movement or pumping action
