Large Diameter TIG Gas Lens Collet Body #17, 18, 26 Torch 2PK (995795-1/8″): Product Breakdown

“>

The Large Diameter TIG Gas Lens Collet Body #17, 18, 26 Torch 2PK (995795-1/8″) is a TIG torch consumable support part used at the front end of the torch assembly. In practice, the collet body holds the tungsten in place and supports gas lens flow through the torch setup. For maintenance buyers and weld support teams, the main question is not whether the part is complex. It is whether the part matches the torch series, fits the tungsten size, and keeps the front end stable enough for consistent work.

This breakdown stays focused on inspection, fit-up, and replacement planning. It does not assume job-specific approvals or torch compatibility beyond the product name. If your torch, cup, collet, or tungsten setup differs, verify before use.

Key Takeaways

• This is a TIG gas lens collet body intended for torch sizes #17, 18, and 26 as stated in the product name.
• The part is packaged as a 2-pack.
• The listed tungsten size is 1/8 inch in the product name.
• For exact fit, torch compatibility, and internal dimensions, verify against your torch setup. Unknown (Verify) where not confirmed by the source.
• Use this part when you need to restore tungsten support, improve consistency at the front end, or replace a worn collet body.

What the Part Does

A TIG gas lens collet body sits inside the torch head and supports the collet and tungsten. In a gas lens setup, it also helps condition shielding gas flow as it exits the torch. That matters when the front end is worn or misaligned. A worn collet body can contribute to tungsten movement, poor grip, inconsistent stickout control, or disturbed shielding gas coverage.

In field terms, the collet body is a support component. It is not the torch body, not the cup, and not the tungsten itself. If the torch is acting up, this part is one of the first consumables to inspect.

Inspect Before You Replace

Before installing a new collet body, work through the front-end stack in order.

• Check: Examine the cup for cracks, heat damage, and cross-threading. If the cup is damaged, gas flow problems may not be caused by the collet body alone.
• Inspect: Look at the tungsten for contamination, dulling, or bent geometry. A damaged tungsten can mimic front-end alignment problems.
• Verify: Confirm the collet size and tungsten size match the setup. The product name indicates 1/8 inch tungsten. Unknown (Verify) for any other size use.
• Check: Make sure the collet body threads and contact surfaces are clean. Debris in the torch head can prevent proper seating.
• Inspect: Look for discoloration, pitting, or distortion that suggests overheating or mechanical wear.

If the tungsten slips, the arc wanders, or the front end cannot hold repeatable stickout, the collet body should be part of the troubleshooting path. For a related support discussion, see TIG Torch Slipping Tungsten? Your Collet Body Is Worn (Here’s the Fix).

Troubleshooting Support: Common Symptoms

• Symptom: Tungsten slips in the torch. Check the collet, collet body, and collet size before assuming the torch head is faulty.
• Symptom: Shielding gas coverage looks uneven. Inspect the gas lens, cup, and front-end cleanliness. Gas flow disruption can come from clogging or damage.
• Symptom: The front end overheats or discolors quickly. Verify amperage, cup selection, and duty cycle practices. Unknown (Verify) for application-specific thermal limits.
• Symptom: Arc starts are inconsistent. Check tungsten condition and seating first. Then inspect the collet body and torch wear surfaces.

Product and Parts Breakdown

The product listed by ArcWeld is Large Diameter Gas Lens Collet Body for TIG torch #17, 18, 26. The product title and source description are the only confirmed identifiers here. Do not assume additional dimensions, thread details, material grades, or certification claims unless your internal sourcing or the vendor page confirms them. Unknown (Verify).

Use case: front-end replacement in a compatible TIG torch setup where a gas lens collet body is required and the tungsten size matches the consumable stack.

Package count: 2-pack, as stated in the product title.

Compatibility note: Torch series #17, 18, and 26 are listed in the product name. Do not assume every torch built around those numbers uses the same front-end consumables without checking your current parts. Verify torch make, series, cup type, collet, and tungsten size before ordering.
