WP-18SC - Weldcraft W-400 Super Cool Replacement Torch Body

Heavy-Duty Performance for Pro Welders

When your welds demand high heat and long arc times, the Weldcraft WP-18SC (W-400 Super Cool) TIG Torch Body is the upgrade your rig needs. Designed for professional welders who push their equipment to the limit, this torch body is built to stay cool even when you are running at 400 amps all day long. If you are working on heavy structural aluminum, thick stainless pipe, or exotic alloys, the W-400SC body ensures your torch doesn't become the bottleneck in your production.

The secret lies in the "Super Cool" technology. Unlike standard water-cooled torches, the WP-18SC features an expanded cooling chamber that wraps around the head and collet body. This draws heat away from the front end faster, keeping your consumables lasting longer and your hand cooler. No more stopping to let the torch cool down or swapping out melted collets halfway through a pass. The rigid neck design gives you the stability you need for walking the cup or maintaining a steady arc in fixed positions.

This is a genuine Weldcraft replacement body, meaning it fits perfectly with your existing W-400 handle and cable sets. It’s built tough to withstand the rigors of the shop floor, from accidental drops to the intense heat of the arc. Whether you are repairing a damaged torch or building a custom high-amp rig, the WP-18SC body delivers the reliability and power density required for top-tier TIG welding. It handles tungsten sizes up to 3/16-inch, giving you the freedom to tackle the thickest jobs with confidence.

Why Choose the W-400SC?

Comfort and efficiency go hand in hand. By maintaining lower operating temperatures, this torch body reduces operator fatigue caused by radiant heat. It allows you to focus on the puddle and your bead profile rather than worrying about equipment failure. Upgrade your setup with the industry standard for heavy-duty water-cooled TIG welding.
