13N27 - 1/16 Inch TIG Collet Body for 9 and 20 Series Torches

Technical Overview of the ESAB 13N27 Collet Body

The ESAB 13N27 Collet Body is a critical consumable component designed for precision TIG welding applications. Engineered to accommodate 1/16-inch (1.6mm) tungsten electrodes, this collet body serves as the primary interface between the collet and the torch head, facilitating both mechanical retention of the electrode and electrical current transfer. It is manufactured from a high-grade copper alloy, chosen for its superior thermal and electrical conductivity properties, which helps minimize resistance heating within the torch head assembly.

This component is standardized to fit the "2 Series" consumable system, making it fully compatible with a broad spectrum of air-cooled and water-cooled TIG torches. Specifically, it fits 9-series (air-cooled) and 20-series (water-cooled) torches, as well as 25-series models. Compatible torch models include the A-125, W-200 Pencil Flex, W-225 Pencil, W-250, W-280, W-310, W-375, A-200 Modular, A-150 Auto, and W-250 Auto. The 13N27 threads directly into the torch body, compressing the collet against the tungsten when the back cap is tightened, ensuring a concentric and secure setup essential for high-quality welds.

In industrial environments, the reliability of the collet body is paramount for maintaining arc stability. A worn or damaged collet body can lead to poor current transfer, arc wandering, or gas turbulence. The ESAB 13N27 is machined to tight tolerances to ensure proper gas flow around the collet and through the nozzle, contributing to effective shielding of the weld pool. It is a direct replacement for any standard 13N27 part, offering seamless integration into existing maintenance schedules for TIG equipment.
