KP44-3545-25 - Lincoln Magnum PRO Liner .035-.045 25ft KP44-3545-25

Smooth Feeding with the Lincoln KP44-3545-25 Liner

Every welder knows that a smooth weld starts with smooth wire feeding. If you are fighting a stuttering arc, erratic wire speeds, or the dreaded bird's nest at the feeder, your liner is often the culprit. The Lincoln Electric KP44-3545-25 is the genuine replacement liner you need to get your Magnum PRO MIG gun back to running like new. Designed for the popular .035 to .045 inch wire sizes, this liner is the backbone of your welding setup, guiding the wire safely from the feeder to the contact tip without snagging or dragging.

At 25 feet long, this liner is built for those long-reach jobs where you are working far from your power source. Pushing wire through 25 feet of cable creates a lot of friction, and cheap aftermarket liners often can't handle the pressure, leading to rapid wear and feeding issues. This genuine Lincoln liner uses high-quality wound steel that stays rigid enough to prevent kinking but flexible enough to move with you as you work around large assemblies. Whether you are welding mild steel in a fabrication shop or running a robotic cell, this liner ensures the wire arrives at the puddle consistently, letting you focus on your bead profile rather than fighting your equipment.

Replacing your liner is one of the cheapest and most effective ways to tune up your welder. Over time, liners fill up with copper dust, dirt, and shop grime, which increases drag and strains your drive motor. Swapping in a fresh KP44-3545-25 takes just a few minutes but can save you hours of frustration. This liner is compatible with Lincoln's Magnum PRO Semi-Auto guns and Robotic Torches, ensuring a perfect fit at the back end and the diffuser. Don't let a $20 part ruin a $1000 job—keep your feed smooth and your arc hot with genuine Lincoln parts.

When installing, remember to lay your gun cable out straight on the floor to ensure the new liner slides in easily without bending. Once seated, trim the liner according to the specific instructions for your Magnum PRO gun to ensure the correct stick-out at the diffuser. This attention to detail ensures optimal gas coverage and electrical contact. Trust Lincoln Electric to provide the durability and precision you need to keep the sparks flying and the metal fusing.
