KP2879-2 - Lincoln Electric KP2879-2 180-Degree Barrel Liner for .035-1/16 Wire

Precision Wire Delivery for 180-Degree Gun Tubes

The Lincoln Electric KP2879-2 Barrel Liner is a critical component designed to maintain the integrity of the wire feed path within 180-degree welding gun tubes. Engineered to precise OEM specifications, this liner facilitates the smooth transfer of welding wire ranging from .035 inches to 1/16 inches in diameter. By providing a dedicated, low-friction conduit within the gun barrel, it minimizes drag and prevents wire shaving, which are common causes of erratic arc performance and contact tip burnback.

In industrial environments where equipment reliability is paramount, using genuine Lincoln Electric parts like the KP2879-2 ensures compatibility and performance. This barrel liner is specifically constructed to withstand the mechanical stresses and heat generated during high-amperage welding operations. It serves as a replaceable wear item that protects the structural integrity of the gun tube itself while ensuring that the filler metal is delivered to the contact tip with consistent speed and alignment.

Proper maintenance of the wire feeding system includes regular inspection and replacement of barrel liners. The KP2879-2 is designed for seamless integration into compatible Lincoln Electric MIG gun assemblies, allowing for quick changeovers that minimize downtime. Whether utilized in automated setups or manual fabrication, this component plays a vital role in achieving high-quality weld deposits by stabilizing the wire as it navigates the final stage of the torch assembly.
