WP-20V - Weldcraft W-250V Water-Cooled TIG Torch Body with Valve

Weldcraft W-250V (WP-20V) TIG Torch Body Features

When your TIG setup requires the power of a water-cooled torch but your machine lacks a gas solenoid, the Weldcraft WP-20V (W-250V) is the torch body you need. This unit is a direct replacement for the standard WP-20 but adds a critical manual gas valve to the neck. This simple yet effective addition puts total control of your shielding gas right at your fingertips. It is the perfect solution for welders running scratch-start or lift-arc TIG rigs off of Stick welders or older power sources where automatic gas control isn't an option. You simply crack the valve before you strike your arc and close it after your post-flow is complete.

Don't let the small size fool you. The WP-20V is a beast when it comes to power handling. Because it is water-cooled, it is rated for a massive 250 amps DC at 100% duty cycle. This means you can weld heavy aluminum or thick steel plate all day long without the torch overheating in your hand. The compact head size helps you get into tight corners and confined spaces that larger 17 or 26 series torches simply can't reach, all while carrying more current than both of them combined. The rigid neck design provides a stable platform for walking the cup or freehand welding, ensuring consistent torch angles.

The WP-20V uses standard 20-series consumables (also known as the 13N series), which are widely available and likely already in your toolbox if you run other water-cooled torches. The body is wrapped in durable, high-dielectric silicone rubber that resists cracking and arcing, ensuring your safety and the longevity of the tool. The water and gas connections are standard for the series, making swap-outs quick and painless.

Whether you are pipe welding in the field with an engine drive or doing precision fabrication in the shop, the WP-20V gives you the flexibility to weld without a solenoid while keeping your cool. It’s a genuine Weldcraft part, meaning the machining tolerances on the threads and the quality of the copper are top-tier, preventing the common issues found in generic knock-offs like thread stripping or coolant leaks.
