WP-18V - Weldcraft W-350V Water-Cooled TIG Torch Body with Valve

Heavy-Duty Water-Cooled TIG Torch Body with Manual Gas Control

The Weldcraft WP-18V (also known as the W-350V) is a premium replacement TIG torch body designed for high-amperage industrial applications requiring precise thermal management and manual gas control. Engineered for continuous production environments, this water-cooled torch body is rated for 350 amps DC and 260 amps AC at a 100% duty cycle. The inclusion of an integrated gas control valve distinguishes this model, providing operators with the ability to manually regulate shielding gas flow directly at the torch. This feature is particularly critical when operating with power sources that lack an internal gas solenoid or during field applications where simplified setups are required.

Constructed with a rugged, rigid body profile, the WP-18V is built to withstand the mechanical stresses of daily industrial use. The water-cooling architecture efficiently dissipates heat, preventing overheating during prolonged welding passes on thick materials such as aluminum and stainless steel. This thermal efficiency not only protects the torch components but also enhances operator comfort by keeping the handle temperature low. The torch body is designed for seamless integration with standard water-cooling systems, ensuring consistent performance under heavy loads.

Compatibility is a key engineering strength of the Weldcraft W-350 series. The WP-18V utilizes standard 10N series consumables (collets, collet bodies, and nozzles), making it interchangeable with widely available parts used in the WP-17 and WP-26 series. This cross-compatibility simplifies inventory management for fabrication shops. Whether used for general fabrication, pipe welding, or heavy equipment repair, the WP-18V delivers the reliability and amperage capacity expected from a genuine Weldcraft product.
