WP-18P - Weldcraft W-500Paut / WP-18P Water-Cooled Machine Torch Body

High-Performance Automation Torch Body

The Weldcraft W-500Paut, also referenced as the WP-18P, is a premium water-cooled TIG torch body designed specifically for mechanized and automated welding applications. Engineered to handle high-amperage demands, this torch body is rated for up to 500 amps DC, making it a robust solution for heavy-industrial fabrication environments where duty cycle and thermal management are critical. The water-cooling system ensures consistent performance during prolonged welding arcs, preventing overheating and extending the lifespan of both the torch and the consumables.

The unit features a 180-degree "pencil" style geometry, which eliminates the angled head found on manual torches. This straight configuration is essential for mounting on linear slides, robotic arms, or fixed automation fixtures, providing a direct line of sight and precise electrode positioning. The barrel is constructed from durable, high-temperature materials capable of withstanding the radiant heat generated during high-current welding processes. Its rugged design ensures reliability in production settings where downtime must be minimized.

One of the key advantages of the W-500Paut is its compatibility with standard industry consumables. It utilizes the same collets, collet bodies, and gas lenses as the popular WP-17, WP-18, and WP-26 series torches. This interchangeability simplifies inventory management for industrial facilities, allowing existing stock of front-end parts to be used across both manual and automated stations. Whether integrated into a custom tube mill or a seam welder, this torch body delivers the stability and power required for precision automated TIG welding.
