09N87 - ESAB 09N87 Collet 1/16" for HW-13 Torch

Precision Component for Mechanized TIG Welding

The ESAB 09N87 Collet is a critical consumable designed specifically for the HW-13 mechanized TIG torch. In the world of automated and heavy-duty industrial welding, the integrity of the electrical connection between the power source and the tungsten electrode is paramount. This collet, sized for 1/16-inch (1.6mm) electrodes, acts as the primary interface for current transfer, ensuring that the arc remains stable and consistent throughout long welding cycles.

Manufactured from high-grade copper alloy, this component is engineered to withstand the thermal stresses associated with mechanized TIG applications. The HW-13 torch is renowned for its high-amperage capabilities, often used in pipe mills, aerospace manufacturing, and pressure vessel fabrication. Consequently, the internal components must resist deformation and oxidation that can lead to arc wander or voltage drops. The 09N87 collet provides a tight, concentric grip on the tungsten, minimizing vibration and ensuring precise electrode positioning—a vital factor when welding to strict code requirements.

Regular maintenance of the torch head assembly is essential for optimal system performance. Over time, collets can wear, lose their spring tension, or accumulate spatter and oxides. Replacing worn collets with genuine ESAB parts like the 09N87 restores the torch's efficiency and protects the more expensive torch body from damage caused by arcing inside the head. This part is a direct replacement for legacy Linde and L-Tec specifications, maintaining the original performance standards of the equipment.

Industrial Reliability

Facilities utilizing the HW-13 system rely on consistent uptime. Using the correct collet size and type prevents production bottlenecks caused by equipment failure. The 09N87 is machined to tight tolerances, ensuring it fits perfectly within the torch body and mates correctly with the collet body or gas lens assembly, providing a leak-free gas path and a low-resistance electrical path.
