The ESAB 85Z99 Insulator Sleeve is a specialized replacement component designed exclusively for the HW-12 series of water-cooled TIG torches. As a critical element of the torch's front-end assembly, this insulator sleeve serves the vital function of electrically isolating the gas nozzle from the current-carrying torch body. By maintaining this barrier, the component prevents dangerous electrical shorts and ensures that the welding arc is directed solely to the workpiece, maintaining process stability and operator safety.
Manufactured to ESAB's rigorous OEM specifications, this sleeve is constructed from durable, high-temperature resistant materials capable of withstanding the intense radiant heat generated during heavy-duty TIG welding applications. The HW-12 torch is often used in high-amperage environments where inferior insulators may crack, carbonize, or fail, leading to gas turbulence or high-frequency leakage. The 85Z99 ensures a precise fit, maintaining the proper alignment of the collet body and nozzle for optimal shielding gas coverage.
Regular inspection and replacement of the insulator sleeve are recommended as part of a preventative maintenance schedule. A compromised insulator can lead to expensive torch body damage or inconsistent weld quality. This genuine ESAB part guarantees compatibility and restores the original performance characteristics of your welding equipment.
