Tweco 1440-1230 Conduit Liner 8 Ft 300A Robotic Mig

Product Description

The TWECO 1440-1230 is a conduit liner from the Robotic R44 Series, designed for use with robotic and fixed automation MIG welding guns. This liner accommodates 0.052 inch to 1/16 inch diameter welding wire and is rated for 300 to 450 amps of continuous welding current. At 8 feet in length, it features a zinc-plated spring wire construction that minimizes corrosion on metal surfaces. A tapered lead angle on the machined conduit stop smooths the transition of welding wire into the MIG gun, reducing feed interruptions. Installation and replacement are handled by welding technicians and automation maintenance personnel.

The 1440-1230 is built for demanding robotic welding environments, including fixed automation cells and semi-automatic MIG setups. The liner measures 0.187 inches outer diameter and 0.078 inches inner diameter, making it suited for integration into robotic torch systems where consistent wire feed is critical to weld quality and cycle time. It is sold individually and is intended as a direct replacement liner in compatible R44 Series robotic MIG gun assemblies.

Key Features

• Zinc-plated spring wire construction minimizes surface corrosion for extended service life
• Tapered lead angle on machined conduit stop smooths welding wire transition into the MIG gun
• Brass alloy machined stop on the back end for secure liner seating
• Part number roll-stamped on the exterior surface for fast field identification
• Rated for 300 to 450 amps to handle high-duty-cycle robotic welding applications
• Accommodates 0.052 inch to 1/16 inch diameter welding wire

Compatibility

Designed for use with TWECO Robotic R44 Series robotic and fixed automation MIG guns requiring a conduit liner with 0.187 inch outer diameter and 0.078 inch inner diameter in an 8-foot length.

Installation Notes

Conduit liner replacement is performed by qualified welding technicians or automation maintenance personnel. Disconnect and de-energize the welding power source and robot controller before removing or installing any gun consumables. Ensure the liner is fully seated against the brass stop at the back end before reassembling the gun neck. Verify wire feed path alignment after installation to prevent premature liner wear or bird-nesting at the drive rolls.
