WP-24FV - Weldcraft A-80 Flex TIG Torch Body with Gas Valve (WP-24FV)

Technical Overview of the Weldcraft A-80 Flex Torch Body (WP-24FV)

The Weldcraft A-80 Flex TIG Torch Body, historically known as the WP-24FV, is a specialized component designed for precision Gas Tungsten Arc Welding (GTAW) applications. Manufactured by Miller Electric under the Weldcraft brand, this torch body is engineered to provide superior access to confined spaces while maintaining reliable electrical conductivity and thermal management. The unit is air-cooled, simplifying the setup by removing the requirement for external water cooling systems, and is rated for 80 Amps DC (50 Amps AC) at a 60% duty cycle. This makes it an ideal choice for light-duty fabrication, aerospace maintenance, and intricate automotive work.

The "FV" designation in the model number indicates two critical features: Flex and Valve. The flexible neck assembly is constructed with a specialized copper core surrounded by high-temperature silicone rubber insulation. This allows the operator to physically bend the torch head to various angles, facilitating a perpendicular torch angle relative to the workpiece even in obstructed areas. The integrated gas control valve is a manual fingertip control located on the torch body itself. This feature provides direct control over shielding gas flow, which is essential when operating with welding power sources that lack an internal gas solenoid valve, such as many stick welders used for scratch-start or lift-arc TIG welding.

The A-80 series utilizes the 24-series front-end consumables, which are significantly smaller than the standard 17 or 26 series parts. This reduction in physical size further enhances visibility and access. The torch body is constructed from high-dielectric materials to ensure operator safety and prevent high-frequency (HF) leakage during arc initiation. It is compatible with standard power cables and hoses designed for the 24-series air-cooled torches.
