0558002690 - ESAB HW-17V Heliarc TIG Torch with Valve and 25mm Dinse

Technical Overview of the ESAB HW-17V TIG Torch

The ESAB HW-17V (SKU: 0558002690) is a robust, air-cooled TIG welding torch designed for light-to-medium duty fabrication and maintenance applications. Belonging to the industry-standard 17-series family, this torch is rated for 150 Amps DC and 115 Amps AC at a 60% duty cycle. The defining technical feature of the 'V' model is the integrated manual gas control valve located on the torch body. This valve allows the operator to manually open and close the shielding gas flow, making it an essential component for welding power sources that do not possess an internal gas solenoid valve, such as many stick welders used for scratch-start TIG or basic DC inverters with Lift-Arc capabilities.

The torch assembly is terminated with a 25mm Dinse connector (often referred to as a 10-25 style connector). This specific connection style is prevalent on compact, portable inverter welding machines, ensuring direct compatibility without the need for complex adapters. The power cable is a one-piece design where the current and gas flow through the same line, optimizing flexibility and reducing the bulk associated with separate lines. The torch head geometry follows the standard Heliarc pattern, ensuring compatibility with all standard 10N series collets, collet bodies, and alumina cups, as well as 57Y back caps.

Constructed with high-temperature silicone rubber insulation, the torch body is resistant to impact and heat cracking, ensuring longevity in industrial environments. The handle is ergonomically shaped with a ribbed texture to provide a secure grip even when wearing heavy welding gloves. This unit is supplied as a complete assembly ready for immediate connection to compatible power sources.

Specifications and Compatibility

The HW-17V utilizes standard consumables shared across the 17, 18, and 26 series platforms. This interchangeability simplifies inventory management for workshops using multiple torch types. The 12.5-foot cable length offers a balance between reach and manageability, suitable for bench work and localized site repairs. The manual valve mechanism is a simple rotary style, providing reliable gas shut-off to prevent waste when not welding.
