45-116-15 - Tweco Style 45-116-15 Steel Liner 15ft .052-1/16

Reliable Wire Feeding with the 45-116-15 Conduit Liner

Keep your MIG welding torch performing at its peak with the 45-116-15 Tweco Style Liner. A worn or clogged liner is often the culprit behind poor arc starts, wire chatter, and burn-backs. Replacing your liner regularly is one of the most cost-effective ways to maintain weld quality. This specific liner is designed to fit 15-foot MIG guns and is compatible with the popular Tweco Professional Choice Series (Models #5 and #6) as well as the EL600.

Engineered for heavy-duty applications, this liner is rated for welding outputs between 500 and 650 Amps. It is sized perfectly for larger diameter wires, specifically .052" and 1/16". The construction features a steel wound spring wire design that offers the flexibility needed to maneuver the gun while maintaining enough rigidity to prevent the liner from collapsing or kinking inside the cable. The zinc plating on the wire acts as a lubricant and a rust inhibitor, ensuring that the welding wire glides smoothly from the feeder to the contact tip.

Installation is straightforward thanks to the industry-standard design. The liner includes a brass alloy stop crimped onto the back end. This stop seats firmly into the gun's power pin, preventing the liner from moving during welding and ensuring proper gas flow alignment. The part number is roll-stamped directly onto this brass stop, so you never have to guess if you have the right part when grabbing a replacement from your tool crib.

Whether you are welding thick structural beams or heavy machinery parts, consistent wire delivery is non-negotiable. This 45-116-15 replacement liner restores the smooth feeding action your welders expect, reducing frustration and rework. It is an essential spare part for any fabrication shop utilizing high-amperage Tweco-style equipment.
