Lincoln Electric KP42-4045-6 Mig Wire Liner 6 Foot

Product Description

The LINCOLN ELECTRIC KP42-4045-6 is a MIG welder wire liner designed to guide welding wire smoothly through a MIG gun cable assembly. It accommodates wire diameters from 0.035 to 0.045 inches and runs 72 inches (6 feet) in total length. Rated for a current range of 200 to 250 amps, this liner is built for solid and flux-cored wire applications where consistent wire feed is critical to weld quality. Welding technicians and fabricators install this component as a replacement or spare liner inside compatible MIG gun cable assemblies to reduce feed resistance and prevent wire kinking or burnback.

This liner is suited for light industrial and professional MIG welding setups operating within the 200 to 250 amp range. It fits applications where 0.035 to 0.045 inch wire is used, including structural fabrication, sheet metal work, and general repair welding. The 6-foot length matches common MIG gun cable configurations used in shop and field welding environments. Welding professionals performing liner replacement as part of routine gun maintenance will find this a direct-fit service part.

Key Features

• Accommodates wire diameters from 0.035 to 0.045 inches
• 72-inch (6-foot) overall length fits standard MIG gun cable assemblies
• Rated for 200 to 250 amps of welding current
• Designed to reduce wire feed resistance and minimize burnback risk
• Direct replacement liner for MIG gun maintenance and repair

Compatibility

Designed as an OEM-style replacement liner for MIG welding guns that accept 0.035 to 0.045 inch wire and use a standard 6-foot cable assembly configuration.

Installation Notes

Liner replacement is performed by welding technicians during routine MIG gun service. Disconnect the welder from power and release wire tension at the drive roll before removing the old liner. Feed the new liner from the gun end through the cable assembly and trim to length if required before seating the contact tip and nozzle. Follow the welder manufacturer's service documentation for liner retention and contact tip torque specifications.
