OVERVIEW

Heavy-Duty Control with the W-350 Valve TIG Torch

When your welding job demands high amperage and you are working with a machine that doesn't automate your gas flow, the Weldcraft W-350 Valve (WP-18V-25) is the torch you need in your hand. This beast of a torch is built to run cool even when you are pushing 350 amps on thick aluminum or steel plate. The water-cooled architecture ensures that the torch head stays within operating temperatures, preventing the meltdown of internal components and keeping your hand comfortable even during continuous passes. The standout feature here is the manual gas valve located on the torch body. It gives you total command over your shielding gas—twist to open before you strike your arc, and twist to close when you're done. This is a game-changer for welders running off engine drives or scratch-start setups where the machine won't manage the gas for you.

Comfort isn't sacrificed for power. The W-350 features a ribbed handle design that improves grip and control, essential for maintaining tight tolerances in out-of-position welds. The 25-foot vinyl cable assembly provides ample reach, allowing you to move around large assemblies or fixtures without dragging the cooler and power source right next to you. The vinyl material is tough enough to withstand the rigors of a shop floor, resisting cuts and abrasion while remaining flexible enough to maneuver the torch into tight corners.

This package is a complete ready-to-weld solution (consumables sold separately or in accessory kits). It includes the heavy-duty torch body, the handle, a long back cap for full-length tungsten, and the tri-cable set for power, water, and gas. If you are upgrading from an air-cooled setup or replacing an old WP-18V, this Weldcraft package delivers the reliability and thermal capacity professional welders trust. Stop stopping to let your torch cool down; switch to the W-350 Valve and keep the arc on.

FAQ

There is no functional difference. W-350 is the new model name for the legacy WP-18 series under the Miller Weldcraft rebranding. Parts and consumables remain interchangeable.

Yes, the W-350 (WP-18) is a water-cooled torch. Operating it without coolant flow will rapidly destroy the power cable and torch head.

The built-in valve allows the operator to manually control shielding gas flow. This is necessary when using power sources that do not have an internal gas solenoid valve.

It uses the standard 3 Series (10N series) consumables, which are common to WP-17, WP-18, and WP-26 torches.

It is rated for 350 Amps DC and 250 Amps AC at 100% duty cycle.

This specific package (WP-18V-25) comes with a vinyl power cable.

Only if you add an external water cooler. The torch itself cannot be run air-cooled.

No, tungsten electrodes and front-end consumables (collets, nozzles) are typically sold separately or in an accessory kit.
