The ITW/Miller LMD3A-15 (and related L3A-15/LAD3A-15) is a 15-foot monocoil MIG gun liner featuring E-Z Feed technology. It is designed for wire diameters ranging from .035 to .045 inches. The liner is constructed from high-carbon music wire with a low-friction, corrosion-resistant coating to minimize wire drag and enhance feeding consistency. It is engineered to lock and concentrically align at both the front and back of the gun to provide a stable wire feed path.
Features
E-Z Feed technology reduces wire drag, birdnesting, and stubbing
Enhanced coil profile reinforces rigidity and wire support to prevent kinking or deformation
Concentric alignment to both the contact tip and the power pin
Front and back locking mechanism ensures a stable wire feed path
Error-proof liner trimming requires no measuring during installation
Color-coded shrink wrap (White) matches power pin cap washer to prevent wire size installation errors
Monocoil design prevents liner collapse during high-duty cycles
