The TWECO 1440-1225 is an R44 Series conduit liner designed for robotic and fixed automation MIG welding applications. This 8-foot liner accepts welding wire in the 0.035 to 0.045 inch diameter range and is rated for use at 300 to 450 amps. Constructed with zinc-plated spring wire, it resists corrosion across the metal surface. A machined tapered lead angle at the conduit entry smooths the transition of welding wire into the MIG gun, reducing feed resistance and minimizing wire buckling during high-cycle automated operation. A brass alloy machined stop on the back end provides positive seating and consistent liner positioning.
The 1440-1225 is built for robotic welding cells and fixed automation MIG gun setups where consistent wire feed and durability under continuous-duty cycles are critical. The liner fits into applications where precise wire guidance reduces downtime and rework. The part number is roll-stamped on the outer surface for fast identification during changeovers and inventory checks, a practical feature in high-volume production environments where multiple liner sizes may be on hand.
Designed for use with robotic and fixed automation MIG guns requiring an 8-foot conduit liner compatible with 0.035 to 0.045 inch welding wire diameter.
Installation is typically performed by a qualified welding equipment technician or automation maintenance technician. Disconnect and de-energize the welding power source and confirm the wire feeder is stopped before removing or installing the liner. Ensure the liner is fully seated against the brass alloy stop before securing the MIG gun connection. Follow the gun and wire feeder manufacturer guidelines for liner retention and trim length.
