13N24 - 13N24 1/8" TIG Collet for 9/20 Series Torches

Technical Overview of the Generic 13N24 Collet

The Generic 13N24 TIG Collet is a critical consumable component designed for precision Gas Tungsten Arc Welding (GTAW). Engineered to accommodate 1/8-inch (3.2mm) tungsten electrodes, this collet is manufactured to strict dimensional tolerances to ensure a concentric grip and optimal electrical contact. It is specifically compatible with the 9, 20, and 25 series TIG torches, which include popular models such as the WP-9 (air-cooled) and WP-20 (water-cooled), as well as their modular and flexible derivatives.

Constructed from high-grade copper alloy, the 13N24 collet excels in thermal and electrical conductivity. In the TIG welding circuit, the collet serves as the primary point of current transfer from the torch body to the tungsten electrode. Poor contact surfaces or inferior materials can lead to resistive heating, arc instability, and premature failure of the torch head. This generic replacement maintains the necessary material properties to handle the amperage ranges typical of 9 and 20 series torches (generally up to 250 amps for water-cooled models) while ensuring efficient heat dissipation.

The split-design of the collet allows it to compress against the tungsten when the back cap is tightened, securing the electrode in position. This mechanism is vital for maintaining a consistent arc length and preventing electrode slippage during operation. Unlike larger torch series (17/18/26), the 9/20 series utilizes the same collet geometry for both standard collet bodies and gas lens assemblies, simplifying inventory management for industrial operations. Regular inspection of collets is recommended; signs of thermal deformation, twisting, or arc erosion on the contact surfaces indicate the need for immediate replacement to preserve weld quality.
