Getting steady shielding gas from a small TIG torch can make the difference between a clean bead and a weld that shows oxidation, porosity, or unstable arc behavior. The Welding Knight TIG Gas Lens Collet Body 45V44 13N23 is a 10-piece consumable set made for welders who use 3/32-inch tungsten with WP-9, WP-20, or WP-25 style TIG torches. It gives you five 13N23 collets and five 45V44 gas lens collet bodies, so you can replace worn parts or keep spares ready at the bench. This review helps you decide whether this set fits your torch, your tungsten size, and the type of TIG work you do most often.
Quick Verdict
Rating: 8.2/10
Best For: TIG welders using WP-9, WP-20, or WP-25 torches with 3/32-inch tungsten electrodes.
Bottom Line: This set is worth considering if you want a simple replacement kit for smoother shielding gas flow and more stable TIG work. The main limitation is size compatibility, since it is built for 3/32-inch tungsten and specific torch series only.
Key Takeaways
- The Welding Knight 45V44 13N23 set includes five 3/32-inch collets and five matching gas lens collet bodies.
- It is designed for WP-9, WP-20, and WP-25 series TIG torches, not larger WP-17, WP-18, or WP-26 torch setups.
- The 45V44 gas lens design helps smooth shielding gas flow compared with a standard collet body, which can improve gas coverage around the tungsten and weld puddle.
- The kit is best for welders who already use 3/32-inch, 2.4mm tungsten electrodes and want multiple replacement consumables in one package.
- It is a consumable part, so you still need to inspect the screen, threads, and collets regularly and replace worn or contaminated pieces.

What Is the Welding Knight TIG Gas Lens Collet Body 45V44 13N23?
The Welding Knight 45V44 13N23 set is a replacement consumable kit for small TIG torch setups. It pairs 13N23 collets with 45V44 gas lens collet bodies, both sized for 3/32-inch, 2.4mm tungsten electrodes.
A gas lens sits at the front of the torch and helps distribute shielding gas more evenly around the tungsten. Compared with a standard collet body, this design can support cleaner shielding coverage and better puddle visibility when your cup, tungsten stickout, gas flow, and torch angle are set correctly.
This is not a full TIG torch kit. It does not replace your torch, cup, back cap, gas supply, regulator, or tungsten electrodes. It is best viewed as a focused replacement pack for welders who already know their torch series and electrode size.
Before You Buy: Confirm your torch series and tungsten size before ordering. This set is for WP-9, WP-20, and WP-25 style torches using 3/32-inch tungsten, so it is not the right match for every TIG torch or electrode size.
Who Should Buy It?
Best For
- You use a WP-9, WP-20, or WP-25 series TIG torch.
- You run 3/32-inch, 2.4mm tungsten for common shop, automotive, fabrication, or repair work.
- You want several replacement collets and gas lens bodies instead of buying one piece at a time.
Skip If
- Your torch is a WP-17, WP-18, WP-26, or another larger torch series that uses different consumables.
- You need collets for 1/16-inch, 1/8-inch, or mixed tungsten sizes.
- You need a complete gas lens kit with cups, insulators, back caps, and tungsten included.
Gas Flow and Arc Control
The main reason to use a gas lens is shielding control. A standard collet body sends gas through ports that can create more turbulent flow, while a gas lens uses a screen-style diffuser to smooth the gas before it exits the cup.
For you, that can mean steadier gas coverage around the tungsten and weld puddle. Better gas coverage can help reduce contamination risks, especially on materials where shielding quality matters, such as stainless steel, aluminum, and other TIG-sensitive workpieces.
The part still needs the rest of your setup to be correct. A gas lens will not fix dirty base metal, a contaminated tungsten, an incorrect flow rate, or a torch angle that pulls air into the shielding zone.
Compatibility and Application
The 45V44 gas lens collet body and 13N23 collet size are intended for 3/32-inch tungsten electrodes in WP-9, WP-20, and WP-25 series torch setups. That makes this set useful for welders who already run one of those torch families and want a direct consumable replacement.
The set also supports compatible 53N series ceramic gas lens cups when your torch front-end parts match. Before installing it, compare the part numbers on your current consumables, check your torch manual, or confirm the replacement chart for your torch brand.
This kit is a practical choice for light fabrication, hobby TIG welding, automotive repair, stainless work, aluminum practice, and general bench use. It is less useful if your shop switches between several tungsten diameters, because the package focuses on one size only.
Pro Tip: Keep one new collet and one new gas lens body aside as a comparison set. When your arc feels less stable or your shielding looks worse, compare the used parts against the unused pieces for thread wear, screen damage, discoloration, or distortion.
Build Quality and Package Count
The set includes ten small consumable pieces: five collets and five gas lens collet bodies. That quantity is useful because collets can lose grip over time, and gas lens screens can become blocked or damaged after repeated use.
The listed item weight is 3.2 ounces, and the package dimensions are compact enough for a toolbox drawer, consumable organizer, or TIG cart. Since these are precision front-end parts, you should store them away from grinding dust, loose metal chips, and moisture.
The article-supported purpose is durability during normal TIG use, but these are still consumables. Treat them as replaceable wear parts, not lifetime torch components.
Installation and Setup
Installation is straightforward when the parts match your torch. Let the torch cool, turn off the machine and gas flow, then remove the cup and old collet body. Thread the 45V44 gas lens body into the torch head by hand first, then tighten it carefully without forcing the threads.
Insert the 3/32-inch tungsten through the 13N23 collet, install the back cap, and set your tungsten stickout based on the cup size and welding position. A gas lens can allow more controlled shielding than a standard collet body, but you still need enough cup coverage to protect the puddle.
Avoid overtightening. Too much force can damage threads, distort small parts, or make future removal harder.
How It Performs in Real Use
For Daily Bench Welding
For common TIG bench work, this set makes sense as a replacement pack for the consumables you touch often. If your old collet does not grip the tungsten evenly or your gas lens screen looks clogged, swapping in fresh parts can help restore a more consistent setup.
For Stainless and Aluminum Practice
Gas coverage matters when you want cleaner-looking TIG beads on stainless or aluminum. This gas lens setup can help create smoother shielding flow, but you still need clean metal, correct gas flow, proper cup size, and a properly prepared tungsten.
For Tight Joints and Better Visibility
A gas lens can give you more flexibility with tungsten stickout than a standard collet body when the setup is correct. That can help you see the puddle better in corners, fillets, and tight access points. Do not overextend the tungsten beyond what your cup and gas flow can shield.
For Long-Term Consumable Rotation
The five-piece count for each component gives you spares for routine replacement. This is useful if you weld often, teach beginners, or keep a TIG setup ready for repair work where a worn collet can slow you down.
How to Use It Correctly
- Match the tungsten size: Use this set with 3/32-inch, 2.4mm tungsten electrodes only.
- Check your torch series: Confirm WP-9, WP-20, or WP-25 compatibility before installing.
- Use the right cup: Pair the gas lens with a compatible 53N series gas lens cup when your torch setup requires it.
- Inspect the screen: Replace the gas lens body if the diffuser screen is blocked, crushed, or contaminated.
- Do not overtighten: Snug is usually enough for small TIG front-end parts.
- Control gas flow: Too little shielding can cause contamination, while too much flow can create turbulence. Follow your welding machine, torch, and gas setup guidance.
Compatibility and Safety Notes
TIG torch consumables are small metal parts that sit close to heat, current, and shielding gas flow. Always let the torch cool before changing them, and avoid touching front-end parts immediately after welding.
Check that the gas lens, collet, cup, back cap, and tungsten all fit together before striking an arc. A loose front-end setup can affect tungsten grip, gas coverage, and torch control.
This product does not include safety gear. You still need a proper welding helmet, gloves, ventilation, eye protection, and safe TIG welding practices for the material you are welding.
Customer Experience and Satisfaction
Buyer feedback for this type of replacement set usually centers on fit, thread quality, tungsten grip, and gas coverage. For this Welding Knight kit, the strongest appeal is its simple 10-piece format for a common 3/32-inch setup.
You should judge the product by how well it fits your torch and how consistently it holds the tungsten. If your torch accepts 45V44 and 13N23 consumables, the set gives you enough pieces to replace worn parts while keeping spares on hand.
Pros and Cons
Pros
- Includes five 13N23 collets and five 45V44 gas lens collet bodies.
- Fits common WP-9, WP-20, and WP-25 TIG torch setups.
- Made for widely used 3/32-inch, 2.4mm tungsten electrodes.
- Gas lens design supports smoother shielding gas flow than a standard collet body.
- Compact package is easy to store with other TIG consumables.
Cons
- Limited to 3/32-inch tungsten, so it will not cover every electrode size.

- Does not include ceramic cups, insulators, back caps, or tungsten electrodes.
Is It Worth the Price?
The Welding Knight 45V44 13N23 set offers strong value if you already use the matching torch series and tungsten size. You get multiple replacement collets and gas lens bodies, which is useful because these parts wear, collect contamination, and can get damaged during regular TIG work.
It is worth considering if you want a small consumable pack for everyday shop use, practice welding, or backup parts on a TIG cart. The value drops if you need a mixed-size assortment or a full front-end kit with cups and extra accessories.
How It Compares to Alternatives
Compared with a standard 13N collet body setup, this 45V44 gas lens set gives you the gas lens design that many TIG welders prefer for smoother shielding coverage. Compared with assorted 45V42 to 45V45 kits, this package is more focused because every piece supports the same 3/32-inch size.
If you use WP-17, WP-18, or WP-26 torches, you should compare larger torch consumables instead. If you switch between several tungsten sizes, an assorted kit may be more convenient than this single-size 10-piece set.
Frequently Asked Questions
What torch models does the Welding Knight 45V44 13N23 set fit?
It is made for WP-9, WP-20, and WP-25 series TIG torches. You should still compare your current torch parts or torch manual before ordering, since some aftermarket torches may use different front-end consumables.
Can I use this set with different tungsten sizes?
No. This set is sized for 3/32-inch, 2.4mm tungsten electrodes. If you use 1/16-inch, 1/8-inch, or mixed tungsten sizes, you need matching collets and gas lens bodies for those sizes.
What comes in the package?
The package includes 10 pieces total: five 13N23 collets and five 45V44 gas lens collet bodies. It does not include cups, tungsten electrodes, back caps, or a TIG torch.
Do I need special cups with this gas lens body?
You need compatible gas lens cups for the torch setup, commonly 53N series cups when the rest of the front-end parts match. Do not assume your standard cup will fit without checking your torch parts chart.
Will a gas lens automatically make my welds cleaner?
A gas lens can improve shielding gas flow, but it does not solve every weld-quality issue by itself. You still need clean base metal, correct gas flow, a clean tungsten, the right cup size, and proper torch angle.
How often should I replace the collet or gas lens body?
Replace the collet when it no longer grips the tungsten securely or shows visible distortion. Replace the gas lens body if the screen is clogged, crushed, heat damaged, or causing inconsistent shielding.
Can I clean and reuse these parts?
You can reuse them if they remain clean, undamaged, and able to hold the tungsten properly. Use gentle cleaning and inspection, and replace any gas lens body with blocked or damaged screen material.
Who should skip this TIG gas lens set?
Skip it if your torch is not a WP-9, WP-20, or WP-25 style setup, or if you do not use 3/32-inch tungsten. You should also skip it if you need a complete kit that includes cups, back caps, insulators, and tungsten electrodes.
The Bottom Line
The Welding Knight TIG Gas Lens Collet Body 45V44 13N23 set is a smart buy for TIG welders who use WP-9, WP-20, or WP-25 torches with 3/32-inch tungsten. Its biggest strength is the focused 10-piece replacement format with gas lens bodies and matching collets, while its main limitation is narrow compatibility. Skip it if you need mixed sizes, larger torch-series consumables, or a complete front-end accessory kit.
