The ESAB 85Z17 TIG Collet is a critical component designed for professional welders who demand precision and reliability from their equipment. Engineered specifically for the Heliarc series of torches, this collet is sized for 5/32-inch (4.0 mm) tungsten electrodes. It serves as the primary interface between the torch current and the electrode, making its material quality and dimensional accuracy vital for maintaining a stable welding arc.
Manufactured from high-grade copper alloy, the 85Z17 offers excellent thermal and electrical conductivity. This ensures that welding current is transferred efficiently to the tungsten with minimal resistance heating, which helps prolong the life of both the collet and the torch head. The split-design allows the collet to compress securely around the electrode when the back cap is tightened, preventing slippage even during positional welding or high-frequency starts.
This component is compatible with a wide range of ESAB torches, including the industry-standard HW-17, HW-18, and HW-26 models, as well as the heavy-duty HW-12. Using genuine ESAB parts guarantees that tolerances are maintained, preventing the common issues of gas turbulence or poor electrical contact often associated with generic aftermarket consumables. Whether you are fabricating heavy aluminum structures or performing high-amperage stainless steel welds, the 85Z17 collet provides the consistent performance required for industrial applications.
