Why this matters

If your TIG arc is wandering, the tungsten is overheating, or shielding gas coverage is inconsistent, the gas lens setup may be the problem. A correct gas lens collet body helps smooth gas flow and improves shielding around the tungsten.

If you are setting up a WP-17, WP-18, or WP-26 style torch, the 45V26 family is a common front-end consumable to verify first. This guide is about fitment, not guesswork. Check the torch body, tungsten size, and cup setup before ordering.

When to replace or upgrade the front end

• Arc starts feel unstable
• Gas coverage looks uneven
• Tungsten contamination happens often
• The collet body is worn, pitted, or damaged
• You need a setup matched to a standard TIG torch body

What to verify before you buy

• Torch model: WP-17, WP-18, or WP-26
• Tungsten diameter: match the 3/32″ size if that is your setup
• Cup size: confirm your cup and back cap arrangement
• Collet body thread and front-end style: match the torch family, not just the size

Recommended use case

Choose this setup if you want a standard TIG consumable path for a common 17/18/26-series torch and you need a verified 45V26 replacement path.

Safety note

Disconnect power before changing TIG consumables. Verify torch and consumable fitment against the manufacturer documentation before use. For procedure-controlled welding, follow the applicable welding code and work instructions.
