KP3364-4 - Lincoln Electric .035-.045 MIG Gun Jump Liner

Optimize Your MIG Gun Performance

The Lincoln Electric KP3364-4 Jump Liner is an integral maintenance component for professional welders utilizing .035" and .045" wire. Jump liners are typically located in the gooseneck of the welding gun, a high-stress area where the wire undergoes significant bending and friction. Over time, the constant passage of welding wire can wear grooves into the liner or accumulate debris, leading to erratic feeding and arc instability. This replacement liner restores the internal integrity of your torch, ensuring that wire feeds consistently from the cable to the contact tip.

Designed to meet the rigorous standards of Lincoln Electric, the KP3364-4 offers superior wear resistance and low friction coefficients. This is particularly important when welding with softer wires or in applications requiring long gun cables where drag must be minimized. By maintaining the correct alignment and support for the wire as it exits the gun, this liner helps maximize the life of your contact tips and diffusers. It is compatible with specific Lincoln Electric MIG gun series that utilize the jump liner system, providing a seamless fit that aftermarket generic parts often fail to achieve.

Regular inspection and replacement of your jump liner can prevent costly downtime. Symptoms of a worn liner include wire chatter, burn-back, and irregular arc starts. By proactively replacing this component with the KP3364-4, you ensure that your welding parameters remain constant and your finished welds meet the required specifications. This part is an essential addition to any welder's preventative maintenance kit.

Invest in genuine Lincoln Electric consumables to protect your equipment investment. The KP3364-4 is built to handle the heat and physical demands of industrial environments, providing reliable service for both manual and automated welding setups. Ensure your .035 and .045 wire applications run without interruption by choosing the correct liner for the job.
