WP-9V-12-R - Weldcraft A-125 Valve Air-Cooled TIG Torch Package, 12.5ft Rubber Cable

Product Overview

The Weldcraft A-125 Valve TIG Torch Package (formerly known as the WP-9V series) represents a premium solution for low-amperage, high-precision welding applications. Engineered for versatility and durability, this air-cooled torch package is rated for 125 amps DC and 100 amps AC, making it the standard choice for aerospace, motorsports, and intricate fabrication tasks where heat input control is critical. The specific configuration of the WP-9V-12-R includes a 12.5-foot (3.8 meter) one-piece power cable manufactured from high-grade rubber, offering superior resistance to abrasion and heat compared to standard vinyl cables.

Technical Capabilities

The defining feature of the A-125 Valve model is the integrated fingertip gas control valve located on the torch body. This mechanical valve provides the operator with direct control over shielding gas flow, a necessity when utilizing welding power sources that do not feature an internal gas solenoid, such as many stick welding machines used for scratch-start or lift-arc TIG processes. The torch body itself is designed to accept the industry-standard Series 2 (13N) consumables, ensuring broad compatibility with existing inventory of collets, collet bodies, and gas lenses. The rigid head design provides a stable platform for consistent electrode manipulation.

Ergonomics and Design

Operator fatigue is significantly mitigated through the A-125's lightweight construction and ergonomic ribbed handle. The handle design promotes a secure grip in various positions, essential for the positional welding often required in pipe and tube fabrication. The torch's compact front-end dimensions allow for excellent visibility of the weld puddle and tungsten electrode, facilitating the high-quality welds expected in sanitary and critical code work. The transition from the legacy WP-9 designation to the A-125 (Amp-125) nomenclature aligns with Miller Weldcraft's streamlined naming convention, yet the product retains the exact form, fit, and function that professionals have relied on for decades.

Package Contents and Compatibility

This package is delivered as a complete ready-to-weld assembly, excluding front-end consumables which must be matched to the specific tungsten diameter required for the job. The assembly includes the torch body with valve, the handle, the 12.5-foot rubber power cable, and a long back cap to accommodate standard 7-inch tungsten electrodes. It is fully compatible with standard 105Z57 power cable adapters (sold separately if not already owned) for connection to standard threaded output studs.
