WP-18SC-25-R - Weldcraft W-400 Super Cool Water-Cooled TIG Torch Kit 25ft

Stay Cool Under Pressure with the W-400

When your TIG welding projects demand high heat and long arc times, the Weldcraft W-400 (formerly known as the WP-18SC) is the torch you want in your hand. Built to handle a massive 400 Amps DC, this 'Super Cool' water-cooled torch takes the heat so you don't have to. It is specifically designed for welders tackling heavy aluminum castings, thick structural steel, or precision pipe work where standard torches would overheat and fail. The secret lies in its improved cooling passage design and heavy-duty copper construction, which keeps the torch head and consumables cooler for longer periods.

Comfort is key when you are under the hood all day, and the W-400 delivers with a textured handle that provides a secure, non-slip grip. This reduces hand fatigue and gives you the fine fingertip control needed for critical welds. The package comes ready to hook up with 25 feet of premium braided rubber cables. Unlike stiff vinyl hoses, these braided lines are flexible and tough, moving with you easily around the shop or inside complex weldments without kinking or leaking.

The kit includes everything you need to upgrade your rig: the W-400 rigid torch body, the comfort handle, and the full tri-cable assembly for power, water, and gas. It utilizes the 3-Series consumable platform but is optimized for heavy-duty stubby collet bodies, giving you excellent gas coverage and arc stability. Whether you are upgrading an old WP-18 or setting up a new high-amperage station, the W-400 delivers the reliability and performance professional welders trust.
