WP-150 Flexible Interchangeable Head TIG Torch Body

Build the TIG torch configuration that fits your welding application.
The WP-150 is a flexible, interchangeable-head TIG torch body designed for improved access, comfort, and control. Its flexible neck helps you reach tight or awkward joints, while the interchangeable design lets you choose the torch head angle and shape that best fits the job.

This 150 Amp air-cooled torch body is ideal for general fabrication, pipe welding, precision work, maintenance, and difficult-to-reach joints where a standard fixed-head torch may limit access.

Why Welders Choose the WP-150

• Flexible Torch Body: Bend the neck to improve access and operator comfort.
• Interchangeable Head System: Choose from multiple head angles and configurations.
• 150 Amp Air-Cooled Performance: Suitable for a wide range of TIG welding applications.
• Customizable Setup: Build the torch around the joint, position, and visibility you need.
• No Gas Valve: Designed for welding machines that control shielding gas through an internal gas solenoid.

Frequently Asked Questions

Does this listing include a torch head?
No. This listing includes the WP-150 torch body only. A compatible interchangeable torch head must be purchased separately.

Does the handle come with the torch body?
No. The required 105Z55R Thread-On Handle is sold separately.

Does the WP-150 have a gas valve?
No. The WP-150 does not include a manual gas valve. It is intended for welding machines that control shielding gas through an internal gas solenoid.

What is the difference between the WP-150 and WP-150V?
The WP-150 does not include a gas valve. The WP-150V includes a built-in manual gas valve for machines that require gas control at the torch.

Which torch head should I choose?
Choose the angle and configuration that best matches your joint access and preferred torch position. Available options include 70°, 90°, and 180° pencil-style heads.

Why use a flexible torch body?
The flexible neck allows you to adjust the torch angle for tighter spaces, improved visibility, and a more comfortable welding position.
