The Weldcraft A-125 Flex (formerly known as the WP-9F) is a premium air-cooled TIG torch head designed for precision and accessibility. Manufactured by Miller Electric under the Weldcraft brand, this torch body is engineered to handle 125 Amps at a 60% duty cycle, making it an ideal choice for light-duty industrial applications, hobbyist fabrication, and intricate aerospace work. The defining feature of this model is its flexible neck, which can be adjusted to various angles, providing superior versatility compared to rigid torch heads.
This torch head belongs to the 9-Series family, often referred to as the A-125 series in modern nomenclature. It utilizes an air-cooling method, removing the requirement for bulky water-cooling equipment, which enhances portability and simplifies setup. The body is constructed from high-grade silicone rubber that resists high temperatures and prevents current leakage, ensuring operator safety and equipment longevity. It is compatible with tungsten electrodes ranging from .020" to 1/8" diameter, allowing for a wide range of welding capabilities on thin-gauge materials.
The Weldcraft 9F head is designed to integrate seamlessly with standard 9-series consumables, including collets, collet bodies, gas lenses, and alumina cups (13N series). This universal compatibility ensures that replacement parts are readily available and affordable. The torch head connects to standard air-cooled power cables designed for 9-series torches, making it a straightforward replacement for damaged or worn-out equipment without necessitating a complete torch package overhaul.
Due to its compact size and amperage rating, the A-125 Flex is specifically suited for welding thin materials such as aluminum, stainless steel, and mild steel sheet metal. It is widely used in automotive motorsports for roll cage and header fabrication, where tight angles are common, as well as in maintenance and repair operations (MRO) where equipment portability is essential.
