Tweco 1440-1231 Conduit Liner 15 Ft Robotic Mig Gun

Product Description

The TWECO 1440-1231 is a 15-foot conduit liner from the Robotic R44 Series, designed to guide welding wire through robotic and fixed automation MIG guns. Built with zinc-plated spring wire, it resists corrosion and supports wire diameters from 0.052 inches to 1/16 inch. The liner is rated for 300 to 450 amps and features an outer diameter of 0.187 inches and an inner diameter of 0.078 inches. A tapered lead angle on the machined conduit eases the transition of welding wire into the gun body, reducing hang-ups and improving feed consistency. Installation and identification are simplified by the part number rolled and stamped directly onto the outer surface.

This conduit liner is suited for industrial MIG welding setups where robotic arms or fixed automation equipment demand reliable wire feed over extended liner lengths. It is a direct-fit component for systems requiring a 15-foot liner run, commonly found in automotive, fabrication, and heavy manufacturing environments. A brass alloy machined stop on the back end ensures proper seating and prevents the liner from shifting during operation. Licensed welding technicians and automation maintenance personnel are the primary installers for this component.

Key Features

• Rated for 300 to 450 amps, suitable for high-amperage robotic MIG welding
• Tapered lead angle on the machined conduit reduces wire transition resistance into the MIG gun
• Zinc-plated spring wire construction minimizes corrosion on the liner surface
• Brass alloy machined stop on the back end ensures secure, consistent seating
• Part number rolled and stamped on the outer surface for quick field identification
• Designed specifically for robotic and fixed automation MIG gun applications

Compatibility

Designed for use with robotic and fixed automation MIG guns requiring a 15-foot conduit liner with a wire diameter range of 0.052 inches to 1/16 inch. Part of the TWECO Robotic R44 Series liner lineup.

Installation Notes

Installation should be performed by a qualified welding technician or automation maintenance professional. Before replacing the liner, power down the welding system and relieve any tension on the wire feed mechanism. Ensure the brass alloy stop seats fully against the gun body before securing the liner in place. Do not force the liner through tight bends, as excessive curvature can restrict wire feed and cause premature wear.
