KP45-3545-6-B10 - Lincoln Magnum PRO Thru-Arm Liner .035-.045 6ft (10-Pack)

Keep Your Robots Running Smoothly

Every welder knows that the liner is the backbone of the MIG gun, and this is even more true for robotic systems where you can't feel the drag in your hand. The Lincoln Electric KP45-3545-6-B10 Thru-Arm Cable Liner is your go-to replacement for keeping Magnum PRO Robotic Torches firing on all cylinders. Designed to handle the most common solid wire sizes—.035 to .045 inches—this liner ensures your wire feeds smoothly through the complex articulations of a robotic arm.

Robotic welding cells are designed for speed and volume, meaning your consumables take a beating. A clogged or kinked liner can cause erratic arcs, wandering welds, and frustrating "burnbacks" that stop production cold. This 6-foot liner is built to fit "Thru-Arm" robot configurations, where the torch cable is routed inside the robot arm for better access and less cable damage. The liner provides a low-friction conduit that protects the wire and ensures it hits the joint exactly where programmed, cycle after cycle.

We know that in a production environment, downtime is the enemy. That's why this product comes in a convenient 10-pack. You don't want to shut down a line waiting for a single $20 part. Keep a pack in your maintenance crib so you can swap out a dirty liner during scheduled downtime or immediately if a feed issue arises. Installation is straightforward, following standard Magnum PRO procedures, allowing you to trim for the perfect fit and get back to welding in minutes. Trust Lincoln Electric quality to keep your automation investments profitable.
