WP-18V-25 - Weldcraft W-350 Valve Water-Cooled TIG Torch Package 25ft

Weldcraft W-350 Valve TIG Torch Package (WP-18V-25)

The Weldcraft W-350 Valve TIG Torch Package, formerly known as the WP-18V Series, is a premium heavy-duty welding solution designed for high-amperage applications requiring precise manual gas control. This water-cooled torch is engineered to handle continuous welding operations up to 350 amps DC and 250 amps AC, making it a staple in industrial fabrication, pipe manufacturing, and aluminum welding environments. The inclusion of a built-in fingertip gas control valve distinguishes this model, providing operators with the ability to manually regulate shielding gas flow directly at the torch. This feature is critical when pairing the torch with welding power sources that lack an internal gas solenoid, such as older stick welders or engine-driven machines adapted for TIG processes.

Constructed with durability and operator comfort in mind, the W-350 Valve torch features a unique cooling design that efficiently dissipates heat, minimizing downtime due to overheating and extending the lifespan of consumables. The package includes a 25-foot (7.6 meter) vinyl power cable assembly, which offers a balance of flexibility and abrasion resistance suitable for shop and field environments. The 3-piece cable configuration separates the power, water, and gas lines, allowing for easier maintenance and replacement if individual lines are damaged. The torch body itself is rigid but designed with an ergonomic handle that promotes a secure grip, reducing hand fatigue during long welding shifts.

As a genuine Weldcraft product (now under the Miller Electric umbrella), the W-350 Valve utilizes standard 3 Series (10N) consumables, ensuring that replacement collets, collet bodies, and nozzles are readily available and cost-effective. The torch package comes complete with the torch body, handle, long back cap, and the full 25-foot cable assembly, ready to be connected to a water cooler and power source. Whether used for precision aerospace work or heavy structural aluminum, the W-350 Valve delivers consistent arc stability and reliable cooling performance.
