OVERVIEW

Master Heavy-Duty TIG Welding with Comfort

Take control of your high-amperage welding projects with the Weldcraft W-350 Valve TIG Torch Package. Formerly known to welders as the legendary WP-18V, this torch has been rebranded under the W-Series but keeps the same rugged performance you trust. If you are pushing 350 Amps on aluminum or heavy steel, air-cooled torches just won't cut it. You need the superior thermal management of the water-cooled W-350 to keep welding continuously without your torch getting too hot to hold.

Why Choose the Valve Model?
Not every welding machine handles gas flow automatically. The "V" in this model stands for Valve, giving you a convenient fingertip control knob right on the torch body. This is a lifesaver for scratch-start TIG setups, engine drives, or older power sources lacking a gas solenoid. You get full control over your pre-flow and post-flow manually, ensuring your weld pool is always protected exactly when it needs to be.

Built for the Grind
This package isn't just about raw power; it's built to last. The 25-foot power cable is encased in high-quality braided rubber. Unlike cheaper vinyl hoses that can melt or crack, braided rubber stays flexible in the cold and resists damage from hot sparks and rough shop floors. The ergonomic handle is shaped to fit naturally in your hand, giving you better torch control in all positions—whether you are welding pipe in a fixed position or fabricating on a bench.

Ready to Weld
This kit comes with everything you need to hook up to your water cooler and machine: the W-350 torch body, the durable handle, a long back cap for full-length tungsten, and the complete tri-cable assembly (power, water, and gas hoses). It uses standard 3-Series consumables (collets, bodies, and cups), so finding spares is never a headache. Upgrade your rig with the W-350 and experience the difference that professional-grade water cooling makes.

FAQ

There is no functional difference. Weldcraft renamed the WP-18 series to the W-350 series to better reflect the amperage rating. The parts and consumables remain interchangeable.

Yes, the W-350 is a water-cooled torch. Operating it without coolant flowing will quickly destroy the power cable and torch head.

The manual valve allows the operator to control shielding gas flow directly at the torch. This is necessary for power sources that do not have a built-in gas solenoid valve.

It uses standard 3 Series (10N series) consumables, which are the same as those used on WP-17, WP-18, and WP-26 torches.

The W-350 is rated for 100% duty cycle at 350 Amps DC and 250 Amps AC, provided proper water cooling is maintained.

This specific package (WP-18V-25-R) comes with a high-durability braided rubber power cable.

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

Yes, it is rated for 250 Amps AC output.
