WP-9P - Miller A-125P Pencil TIG Torch Body

Weldcraft A-125P (WP-9P) Pencil TIG Torch Body

The Weldcraft A-125P, formerly known as the WP-9P, is a specialized air-cooled TIG torch body designed for precision welding in the most restricted environments. As part of the renowned Weldcraft A-Series (formerly WP Series), this torch body is engineered to provide welders with the versatility needed for intricate fabrication tasks where standard angled torches simply cannot fit. The "P" designation stands for "Pencil," referring to the completely straight, 180-degree head angle that streamlines the profile of the torch, effectively turning it into a linear extension of the welder's hand. This design is indispensable for applications such as welding inside tubing, roll cages, exhaust manifolds, and complex aircraft components.

Rated for 125 amps DC and 100 amps AC at a 60% duty cycle, the A-125P offers sufficient power for light-to-medium gauge materials typically encountered in precision aerospace, motorsports, and artistic fabrication. Being an air-cooled torch, it offers the benefit of portability and simplicity, removing the requirement for a water-cooling system and the associated hoses and pumps. This makes it an excellent choice for field work or mobile welding stations where equipment footprint must be minimized. Despite its compact size, the torch body is constructed with high-quality copper components to ensure efficient heat dissipation and consistent electrical conductivity.

One of the significant operational benefits of the A-125P is its consumable compatibility. It utilizes the same front-end parts—collets, collet bodies, and gas cups—as the standard WP-9, WP-20, and WP-25 series torches. This interchangeability reduces inventory costs for shops that already utilize these popular torch models, as there is no need to stock a separate line of consumables for the pencil torch. The torch body also features a quick-release tungsten adjustment, allowing operators to easily extend or retract the electrode to suit the immediate requirements of the joint geometry. Whether you are a professional fabricator dealing with difficult access points or a hobbyist looking for a specialized tool for detailed work, the Weldcraft A-125P delivers the reliability and performance associated with the Miller and Weldcraft brands.
