0700009018 - ESAB 2.0mm TIG Torch Collet Body

Precision Engineering for GTAW Applications

The ESAB 0700009018 Collet Body is a critical component engineered for professional Gas Tungsten Arc Welding (GTAW). Designed specifically to accommodate 2.0mm diameter tungsten electrodes, this collet body plays a pivotal role in the electrical and thermal management of your TIG torch assembly. It is manufactured from a high-grade copper alloy, selected for its superior thermal conductivity and resistance to mechanical deformation at elevated temperatures.

In a TIG torch assembly, the collet body performs two primary functions: it houses the collet that grips the electrode, and it transfers the welding current from the torch head to the electrode itself. The ESAB 0700009018 is machined to tight tolerances to ensure concentricity. This precision is vital for maintaining a centered arc, which directly correlates to weld pool control and bead consistency. A poorly machined or worn collet body can lead to an off-center tungsten, resulting in erratic arcs and uneven heat input.

Furthermore, the design of this collet body facilitates smooth gas flow. While it is not a gas lens, its geometry is optimized to allow shielding gas to pass through to the ceramic cup with minimal turbulence, protecting the weld pool from atmospheric contamination. It is compatible with standard ESAB SR-B series torches and other torches adhering to similar international standards. This makes it a versatile addition to inventory for shops running multiple torch setups.

Regular inspection and replacement of the collet body are recommended as part of a preventative maintenance schedule. Signs of wear include thread damage, discoloration from overheating, or an inability to tighten the collet sufficiently. Using a fresh ESAB collet body ensures that the full amperage of your machine is delivered to the arc without resistive losses, providing the clean, high-quality welds that professional fabricators demand.
