35856 - ESAB Heliarc HW-17V Air-Cooled TIG Torch, 25ft, with Valve

Technical Overview of the ESAB HW-17V TIG Torch

The ESAB HW-17V-2TL (SKU: 35856) is a premium air-cooled TIG welding torch designed for professionals requiring a reliable 150-amp solution. Part of the renowned Heliarc family, this torch is engineered to meet the rigorous demands of industrial welding while maintaining compatibility with standard 17-series consumables. The 'V' designation indicates the presence of a manual gas control valve located on the torch body, a critical feature for welding power sources that do not possess an internal gas solenoid valve, such as many stick welders used for scratch-start TIG applications.

This assembly features a 25-foot reach, utilizing a 2-piece cable configuration. In a 2-piece system, the power conductor and the gas hose are separate lines, which often provides greater durability and lower replacement costs compared to single-piece coaxial cables. The torch is rated for 150 amps at a 60% duty cycle (DC) or roughly 115 amps (AC), making it suitable for welding mild steel, stainless steel, and aluminum in light-to-medium fabrication roles. The head angle is the standard 70 degrees, offering optimal electrode positioning for most fillet and butt weld configurations.

The HW-17V utilizes industry-standard front-end parts, including 10N series collets and collet bodies, and 57Y series back caps. This universal compatibility ensures that replacement parts are readily available and cost-effective. The torch handle is designed with high-impact materials to resist cracking and heat damage, ensuring a long service life in shop environments.
