QAK-2 - ESAB QAK-2 TIG Torch Consumable Kit for 17/18/26 Series

Technical Overview

The ESAB QAK-2 (Internal SKU: ESBQAK-2) is a specialized accessory kit engineered for Gas Tungsten Arc Welding (GTAW) torches within the 17, 18, and 26 series classifications. This kit provides a curated selection of front-end consumables necessary to configure a standard TIG torch for operation. It is designed to meet the rigorous demands of industrial welding environments, offering components manufactured to precise tolerances for optimal electrical conductivity and gas flow dynamics.

The kit addresses the universal compatibility requirements of the 17 (air-cooled), 18 (water-cooled), and 26 (air-cooled) torch series, which share a common front-end geometry. Included in the package are collets and collet bodies in assorted standard sizes, typically covering the most frequently used tungsten electrode diameters. The collets are crafted from high-grade copper alloy to ensure secure electrode gripping and efficient current transfer, minimizing resistance heating at the contact point.

Also included are alumina ceramic nozzles (cups) designed to withstand high thermal shock and direct shielding gas flow effectively over the weld pool. The provision of both long and short back caps enhances the versatility of the torch, allowing operators to switch between standard configurations and short-profile setups for accessing confined spaces. This kit serves as an essential maintenance and setup package for professional welders requiring reliable, OEM-quality components.
