WP-9V - Weldcraft A-125V Air-Cooled TIG Torch Body with Valve (WP-9V)

Product Overview

The Weldcraft A-125V TIG Torch Body (formerly known as the WP-9V) is a premium air-cooled torch component designed for precision welding applications requiring up to 125 amps. Manufactured by Miller Electric under the Weldcraft brand, this torch body is engineered to provide reliable performance in light-duty industrial and hobbyist environments. The defining feature of the A-125V is its integrated gas control valve, which provides manual on/off control of shielding gas flow directly at the torch handle. This capability is essential for welding setups utilizing power sources that lack internal gas solenoids, such as many stick welders used for scratch-start TIG processes.

Technical Specifications and Compatibility

The A-125V is rated for 125 amps DC and approximately 100 amps AC at a 60% duty cycle, making it suitable for welding thin-gauge materials including steel, stainless steel, and aluminum. The torch body features a rigid neck design that offers stability and precise electrode placement. It is fully compatible with the standard 13N series consumables (collets, collet bodies, and alumina nozzles), ensuring easy procurement of replacement parts. Furthermore, the front-end parts are interchangeable with the water-cooled WP-20 and WP-25 series torches, allowing facilities to standardize inventory across different torch models.

Construction and Durability

Constructed from high-grade copper components and insulated with high-temperature silicone rubber, the A-125V is built to withstand the thermal stresses of welding while protecting the operator from electrical hazards. The air-cooled design eliminates the need for bulky water coolers and hoses, simplifying the equipment setup for mobile operations. The manual gas valve is designed for smooth operation, allowing for precise pre-flow and post-flow management by the operator. This torch body serves as a direct replacement for damaged WP-9V units or as a core component for building a custom air-cooled TIG package.
