WP-18SC-25 - Weldcraft W-400 (WP-18SC) 400A Water-Cooled TIG Torch Package, 25ft

Heavy-Duty Industrial TIG Welding Solution

The Weldcraft W-400 Super Cool™ TIG Torch Package (formerly known as the WP-18SC) is a premier solution for high-amperage industrial welding applications. Engineered to overcome the thermal limitations of standard torches, the W-400 utilizes a unique water-cooling design that significantly improves heat dissipation. This allows the torch to maintain a 100% duty cycle at 400 Amps DC and 280 Amps AC, making it ideal for continuous, heavy-duty fabrication tasks where equipment reliability is paramount.

This package, SKU WP-18SC-25, comes complete with a 25-foot (7.6 meter) cable assembly. The power cable is constructed from durable vinyl, configured in a 3-piece design that separates the power conductor from the gas and water lines for easier maintenance and flexibility. The torch head features a rigid design without a valve, streamlined for use with power sources that manage gas flow via a solenoid. A key technical advantage of the W-400 is its compatibility with heavy-duty stubby collet bodies, which not only enhance gas coverage but also increase the cooling capacity around the tungsten electrode.

Durability is central to the W-400's construction. It employs robust copper components that resist thermal deformation and maximize current transfer efficiency. The included textured handle is ergonomically designed to reduce operator fatigue during long weld cycles while providing a secure grip for precision manipulation. By minimizing overheating, the W-400 reduces downtime associated with torch cooling and component failure, ensuring consistent productivity in the most demanding environments.
