WP-17F - Miller Weldcraft A-150 Flex TIG Torch Body (WP-17F)

Product Overview

The Miller Weldcraft A-150 Flex (formerly known as the WP-17F) is a high-performance air-cooled TIG torch body designed for versatility and durability in light-to-medium duty welding applications. Engineered to meet the rigorous demands of professional fabrication, this torch body features a flexible neck that can be adjusted to various angles, providing superior access to hard-to-reach joints and confined spaces where rigid torches cannot perform effectively. The unit is rated for 150 amps DC and 115 amps AC at a 60% duty cycle, making it a robust choice for welding materials such as mild steel, stainless steel, and aluminum.

Technical Construction

Constructed with heavy-duty copper components, the WP-17F ensures optimal electrical conductivity and efficient heat dissipation, which is critical for air-cooled systems. The body is encased in high-temperature silicone rubber insulation that not only protects the internal components from environmental damage but also prevents high-frequency voltage leaks, ensuring operator safety during arc initiation. The flexible coil mechanism within the neck is designed to withstand repeated adjustments without losing structural integrity or gas flow consistency.

Compatibility and Integration

This torch body is part of the widely used A-150 (17 Series) family, ensuring broad compatibility with industry-standard consumables. It utilizes the 10N series collets, collet bodies, and alumina cups, as well as 57Y series back caps. This universal compatibility simplifies inventory management for workshops and ensures that replacement parts are readily available. The WP-17F connects easily to standard 1-piece or 2-piece power cables, allowing for seamless integration into existing TIG setups without the need for specialized adapters.

Operational Efficiency

By eliminating the need for a water-cooling system, the A-150 Flex offers a portable and cost-effective solution for maintenance, repair, and field applications. The lightweight design reduces operator fatigue during extended welding sessions, while the flexible head minimizes the need for awkward body positioning. Whether used for intricate metal art, automotive fabrication, or general repair, the Miller Weldcraft WP-17F delivers consistent arc performance and reliable gas coverage.
