14201127 - Tweco 42-116-15 MIG Gun Liner 1/16in 15ft

Tweco 42-116-15 Conduit Liner Overview

The Tweco 42-116-15 Conduit Liner (SKU: 14201127) is a premium replacement component designed for industrial MIG welding applications. Engineered by ESAB under the renowned Tweco brand, this liner is part of the 42 Series, specifically manufactured to accommodate 1/16-inch (1.6mm) welding wires. The liner measures 15 feet (approximately 4.6 meters) in length, making it suitable for standard MIG gun cable assemblies of corresponding length.

Constructed from zinc-plated oil-tempered spring steel, this conduit offers superior mechanical properties compared to standard bare steel liners. The zinc plating serves a dual purpose: it provides significant corrosion resistance, protecting the liner from environmental moisture and oxidation during storage or downtime, and it offers a lower coefficient of friction. This reduction in friction is critical for maintaining a smooth, uninterrupted wire feed, thereby reducing the load on the wire feeder motor and minimizing the risk of feedability issues such as burn-back or erratic arc stability.

The precision winding of the spring steel ensures flexibility without compromising the structural integrity of the inner diameter. This balance allows the liner to navigate the curvature of the MIG gun cable while maintaining a consistent path for the welding wire. It is an essential consumable for maintaining the performance of Tweco Spray Master and other compatible MIG guns utilizing the 42 Series platform. Regular inspection and replacement of the conduit are recommended to adhere to quality standards in high-production welding environments.
