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

Precision Wire Delivery for Robotic Automation

In the high-stakes world of robotic welding, consistency is the currency of productivity. The Lincoln Electric KP45-3545-6-B10 Thru-Arm Cable Liner is engineered to deliver that essential consistency, specifically designed for Magnum PRO Robotic Torches. This liner facilitates the smooth transfer of welding wire from the feeder to the contact tip, a critical path where even microscopic friction can lead to arc instability or downtime. Optimized for wire diameters ranging from .035 to .045 inches (0.9-1.2 mm), this component is a vital safeguard against the common pitfalls of automated welding, such as birdnesting and burnback.

The "Thru-Arm" designation indicates that this liner is tailored for robotic arms where the cable assembly runs through the center of the robot's casting (hollow wrist or through-arm design). This configuration reduces cable whipping and stress but requires a liner that can withstand specific torsional forces while maintaining a concentric path for the wire. Lincoln Electric utilizes high-grade materials to ensure the liner's internal surface remains smooth over extended duty cycles, reducing drag and wear on the wire coating. At 6 feet (1.8 meters) in length, it provides the necessary reach for standard robotic setups without excessive slack that could induce feeding resistance.

Supplied in a pack of 10, this SKU allows maintenance departments to maintain a lean yet sufficient inventory of critical consumables. Regular replacement of cable liners is a preventative maintenance best practice that directly correlates to robot uptime and weld quality. By choosing genuine Lincoln Electric parts, operators ensure dimensional accuracy and material compatibility with their Magnum PRO systems, preserving the integrity of the entire welding cell.
