WP18SC25RM - Miller Weldcraft W-400 Water-Cooled TIG Torch Kit, 400A, 25ft Braided Rubber

Stay Cool Under Pressure

When you are pushing 400 amps, the last thing you want is a torch that gets too hot to hold. The Miller Weldcraft W-400 Super Cool (formerly the WP-18SC) is built for welders who need to run hot and long without sacrificing comfort. This water-cooled beast is designed to endure the most demanding TIG applications, keeping your hand cool even when you are blasting through thick aluminum or steel plate. The secret lies in the heavy-duty copper components and the specialized stubby collet body, which work together to pull heat away from the front end and improve gas coverage for a smoother, more stable arc.

Comfort is king on long shifts, and the W-400 delivers with a textured handle that gives you a secure, non-slip grip. This means better torch control and less hand fatigue, allowing you to focus on laying down perfect beads. The kit comes with a 25-foot braided rubber power cable that is tough enough to survive the shop floor but flexible enough to maneuver around jigs and fixtures without fighting you. Unlike stiff vinyl cables, the braided rubber resists kinking and melting, giving you one less thing to worry about.

This package gets you up and running fast, including the torch body, handle, and all the necessary hoses. It uses standard 3 Series consumables, so you likely already have the parts you need in your box. Whether you are welding heavy pipe or structural components, the W-400 Super Cool gives you the power and reliability to get the job done right, weld after weld.
