85Z06 - ESAB 85Z06 1/4-Inch TIG Collet for HW-13 Torches

Heavy-Duty TIG Consumable for Industrial Applications

The ESAB 85Z06 Collet is a specialized welding consumable designed to accommodate 1/4-inch (6.4 mm) tungsten electrodes. This component is critical for heavy-duty TIG welding operations that utilize high-capacity torches such as the HW-13 and PTW-500 series. Manufactured to precise tolerances, this collet ensures optimal alignment of the tungsten electrode within the torch body, which is essential for maintaining a focused and stable arc during demanding welding procedures.

Constructed from a high-grade copper alloy, the 85Z06 collet offers superior thermal and electrical conductivity. In high-amperage applications—common when using 1/4-inch tungsten—efficient current transfer is paramount to prevent overheating and ensure the longevity of both the consumable and the torch head. The material composition is selected to resist deformation under thermal stress, maintaining a tight grip on the electrode even after prolonged use at high duty cycles.

This product is an OEM-quality replacement part, ensuring seamless compatibility with existing ESAB and Linde-style heavy-duty water-cooled torches. Proper maintenance of the collet is vital for weld quality; a worn or deformed collet can lead to poor arc starts, wandering arcs, and inefficient shielding gas coverage. By replacing worn components with the genuine 85Z06, operators can restore their equipment to peak performance levels.

The 1/4-inch size is specifically tailored for thick-plate welding and automated TIG processes where deposition rates and penetration depth are critical. Whether used in pipe fabrication, aerospace, or heavy manufacturing, this collet provides the reliability required for industrial-grade welding tasks.
