13N25 - 13N25 Standard Collet Body .020 for 9/20 Torches

Precision TIG Components

The ESAB 13N25 Collet Body is a critical component designed for precision TIG welding applications requiring the use of 0.020-inch (0.5mm) tungsten electrodes. Engineered to exacting tolerances, this collet body serves as the primary interface for current transfer within the torch head assembly, ensuring stable electrical conductivity and efficient heat dissipation during operation. It is specifically manufactured to be compatible with standard 9, 20, and 25 series TIG torches, making it a versatile addition to any professional welder's inventory of consumables.

Constructed from high-grade copper alloy, the 13N25 collet body offers superior durability and resistance to thermal deformation. In the TIG welding process, the collet body houses the collet and tightens against the torch head to secure the tungsten electrode in place. A precise fit is essential to prevent arcing within the torch body, which can lead to premature failure of the torch head or inconsistent arc characteristics. This specific model is designed for low-amperage, fine-detail work where a 0.020-inch tungsten is utilized, often found in aerospace, electronics, and thin-gauge sheet metal fabrication.

The design of the ESAB 13N25 facilitates smooth gas flow around the electrode, contributing to adequate shielding coverage of the weld pool. While not a gas lens, its standard configuration provides reliable performance for general purpose and precision welding tasks. Regular inspection and replacement of collet bodies are recommended to maintain optimal torch performance, as thread wear and thermal cycling can eventually compromise the mechanical connection. This package contains five (5) collet bodies, ensuring that operators have immediate access to replacements, minimizing downtime in production environments.
