17F - Weldcraft A-150 Flex (17F) Air-Cooled TIG Torch Body

Weldcraft 17F Flex Torch Head (A-150 Series)

The Weldcraft 17F Flex Torch Head, also known as the A-150 Flex, is a premium replacement body designed for the widely used WP-17 series air-cooled TIG torches. Engineered by Miller Weldcraft, this torch head combines durability with exceptional versatility, making it an essential component for welders who frequently encounter difficult angles or obstructed joints. The defining feature of the 17F is its flexible neck, which can be adjusted to various angles, allowing the operator to maintain the optimal torch position even in the most confined spaces.

Rated at 150 amps for DC welding and 115 amps for AC welding at a 60% duty cycle, this torch head provides ample power for a wide range of light-to-medium duty fabrication tasks. It utilizes the standard air-cooling method, which simplifies setup by removing the need for water coolers and hoses, making it ideal for field work and portable applications. The body is constructed from high-grade copper components to ensure efficient heat dissipation and electrical conductivity, while the exterior is insulated with high-dielectric silicone rubber. This insulation not only protects the welder from electrical hazards but also withstands the high temperatures associated with TIG welding, preventing cracking and leakage over time.

Compatibility is a key strength of the Weldcraft 17F. It accepts standard 17-series consumables, including collets, collet bodies, gas lenses, and alumina cups, allowing you to use existing inventory without purchasing specialized parts. Whether you are welding mild steel, stainless steel, or aluminum, the A-150 Flex torch head delivers the control and reliability needed for high-quality welds. It is designed to handle tungsten electrodes ranging from .020" to 5/32", providing flexibility in arc characteristics and penetration profiles.
