WP-17-12-MF - Weldcraft A-150 (WP-17) TIG Torch Package, 12.5ft Mono-Flex Cable

Technical Overview of the Weldcraft A-150 TIG Torch Package

The Weldcraft A-150 TIG Torch Package (SKU: WP-17-12-MF) represents the industry standard for 150-amp air-cooled TIG welding applications. Formerly known as the WP-17 series, the A-150 integrates legacy compatibility with modern ergonomic enhancements. This package is engineered for general fabrication, maintenance, and repair operations where portability and ease of use are paramount. The torch body features a rigid head design without a gas control valve, making it suitable for power sources with built-in gas solenoids.

Technically, the A-150 is rated for 150 Amps DC and 115 Amps AC (60% duty cycle typical for this class). It utilizes the widely available 10N series (3 Series) consumables, ensuring that collets, collet bodies, and nozzles are easily sourced and interchangeable with existing WP-17 setups. The electrode capacity ranges from .020 inch (0.5 mm) to 1/8 inch (3.2 mm), accommodating a broad spectrum of tungsten sizes for various material thicknesses.

A critical component of this package is the 12.5-foot (3.8 m) Mono-Flex™ power cable. Unlike standard vinyl cables, this braided rubber cable offers superior resistance to heat and abrasion while maintaining flexibility in cold environments. The 1-piece cable design combines power and gas delivery into a single line, simplifying the connection to the welding machine. The package includes the torch body, a ribbed handle for thermal management, a long back cap for full-length tungsten, and the power cable assembly.

This torch is ideal for industries such as aerospace, food and beverage, and petrochemicals where reliable, air-cooled performance is required without the complexity of water-cooling systems. The A-150's design ensures a proper relationship between the torch and the weld joint, providing maximum maneuverability in tight spaces.
