WP17V25RM - Weldcraft A-150 Valve TIG Torch Kit, 25ft Rubber Cable

Technical Overview: Miller Weldcraft A-150 Series TIG Torch

The Miller Weldcraft A-150 TIG Torch Kit (SKU: WP17V25RM) represents the evolution of the industry-standard WP-17 series, engineered for general-purpose welding applications requiring up to 150 amps. This air-cooled torch system is designed to provide reliable performance in a lightweight package, eliminating the need for complex water-cooling infrastructure. The specific configuration of this model includes a gas control valve directly on the torch body, making it an essential tool for welding power sources that do not possess an internal gas solenoid, such as many stick welding machines used for scratch-start or lift-arc TIG processes.

Technically, the A-150 is rated for 150 amps DC and approximately 115 amps AC at a 60% duty cycle. The torch body features the proprietary Diamond Grip™ design, which integrates ergonomic contact points to ensure secure handling and precise torch manipulation. The 'V' designation in the SKU indicates the presence of the manual gas valve, a knurled control knob located at the neck of the torch, allowing the operator to manually open shielding gas flow before striking an arc and close it upon completion. This mechanical control is vital for field applications where automated gas pre-flow and post-flow are not available via the power source.

The power cable assembly in this kit is a 25-foot (7.6 meter) single-piece conductor encased in high-durability rubber. Unlike standard vinyl cables, the rubber jacket offers superior resistance to heat, abrasion, and cold-weather cracking, ensuring longevity in industrial environments. The torch utilizes the standard Weldcraft 10N series (3 Series) consumables, including collets, collet bodies, and alumina nozzles, ensuring that replacement parts are universally available and cost-effective. The system is designed to minimize downtime through its robust construction and ease of maintenance, adhering to Miller's rigorous standards for arc welding equipment.
