Small TIG torch parts can affect arc control, tungsten grip, and downtime more than many welders expect. The Mtsooning 5PCS 45V44 TIG Welding Collet is a small replacement part made for welders who use 2.4mm, or 3/32 inch, tungsten electrodes with compatible TIG torches. Its main strengths are the copper construction, five-piece pack, and fitment for several WP-style torch models. The main limitation is simple but important: you need to confirm your torch model and parts setup before buying.
Quick Verdict
Rating: Recommended with caveats, 8/10
Best For: TIG welders who need spare 2.4mm / 3/32 inch collets for WP-9, WP-20, WP-24, or WP-25 torch setups.
Bottom Line: The Mtsooning 5PCS 45V44 collet set makes sense if you want several copper replacement collets for common TIG torch models. It is not the right buy if your torch uses a different collet series, tungsten size, or non-matching parts stack.

What Is the Mtsooning 5PCS 45V44 TIG Welding Collet?
The Mtsooning 5PCS 45V44 TIG Welding Collet is a replacement collet set for TIG welding torches. A collet holds the tungsten electrode inside the torch assembly, so proper fit matters for stable setup and predictable welding performance.
This set is built around a 2.4mm, or 3/32 inch, tungsten size. The article lists compatibility with WP-9, WP-20, WP-24, and WP-25 TIG welding torches, which makes it useful if your current torch setup matches those models.
The five-piece pack also gives you spares. That helps if you weld often, switch parts during maintenance, or want backups ready when a collet becomes worn, heat-marked, or less secure.
Before You Buy: Match the 45V44 part number, 2.4mm / 3/32 inch tungsten size, and your TIG torch model before ordering. A correct torch model still needs the right matching collet body, gas lens, cup, and back cap setup.
Who Should Buy It?
Best For
- TIG welders using 2.4mm / 3/32 inch tungsten electrodes.
- Users with WP-9, WP-20, WP-24, or WP-25 torch models listed by the article.
- Welders who want a small pack of spare copper collets for replacement and maintenance.
Skip If
- Your TIG torch uses a different collet series or part number.
- You need collets for a tungsten size other than 2.4mm / 3/32 inch.
- You are looking for a full torch consumables kit with cups, collet bodies, and back caps included.
Material Quality and Durability
The source article describes the Mtsooning 45V44 collets as copper parts. Copper is commonly used in TIG torch consumables because it handles heat transfer well in the torch assembly.
For you, the practical benefit is reliability during normal welding sessions. A solid collet should hold the tungsten firmly and support a consistent setup when it fits the torch correctly.
Still, this is a wear part. Heat, repeated tightening, dirt, and normal use can eventually reduce performance. If the collet no longer grips the tungsten well, replacement is safer than forcing more use from a damaged part.
Fit and TIG Torch Compatibility
The article lists the Mtsooning 45V44 collet for WP-9, WP-20, WP-24, and WP-25 TIG welding torches. That range gives it useful flexibility if you own one of those supported torch models.
| Torch Model | Article-Supported Fit | Buyer Note |
|---|---|---|
| WP-9 | Yes | Confirm your torch consumable setup before ordering. |
| WP-20 | Yes | Check that you need the 45V44 part and 3/32 inch size. |
| WP-24 | Yes | Match all related consumables, not only the torch number. |
| WP-25 | Yes | Useful if your torch setup accepts this collet series. |
Compatibility is the biggest buying factor with this product. A collet is a small part, but a wrong size can cause poor tungsten grip, setup frustration, or wasted time during a job.
Installation and Replacement Benefits
The source article notes that installation does not require specialized tools. That makes the set practical for quick replacement when you already know how your TIG torch assembly comes apart.
For normal use, you remove the torch parts, replace the worn collet with the matching 45V44 collet, and reassemble the torch with the correct tungsten size. You should follow your torch manual or parts diagram if you are unsure about the order of the components.
The five-piece count is helpful because collets are small and easy to misplace. Keeping extras in your welding drawer or consumables box can reduce downtime when one part wears out.
Pro Tip: Store the spare collets in a labeled parts container with your matching 3/32 inch tungsten electrodes. That makes it easier to avoid mixing them with other TIG sizes.
How It Performs in Real Use
For Routine TIG Welding
For regular TIG work, the main job of this collet is simple: hold the tungsten electrode securely inside the torch. When the part fits correctly, it helps you maintain a steady torch setup without repeated adjustment.
For Maintenance and Replacement
This set is useful when you want small replacement parts ready before a collet fails. If you notice cracking, heavy discoloration, or weaker electrode grip, swapping in a fresh collet can help restore a more dependable setup.
For Small Shops and Home Welders
A five-piece pack works well for home garages, repair benches, and small welding stations. You do not need a large bulk kit if you only want spare 45V44 collets for a compatible torch.
For Longer Welding Sessions
During extended work, heat and repeated use can stress consumables. Having several collets on hand lets you replace a questionable part instead of pushing through with a worn one.
How to Use It Correctly
First, confirm that your torch model and collet part number match. Then confirm that you are using 2.4mm, or 3/32 inch, tungsten electrodes.
Do not overtighten the torch assembly to compensate for a worn or mismatched part. If the tungsten does not sit securely, stop and inspect the collet, collet body, and related torch parts.
Keep the collets clean and dry when stored. Dirt, debris, and damage can affect how well the collet seats inside the torch.
Compatibility and Safety Notes
TIG welding involves heat, electricity, bright arc light, and hot metal. Always use proper welding PPE, including a welding helmet, gloves, protective clothing, and safe ventilation for your work area.
Let the torch and consumables cool before handling or replacing parts. A copper collet can still be hot after welding, even though it is small and easy to overlook.
You should also inspect the full torch assembly, not only the collet. A worn collet body, damaged back cap, incorrect cup, or wrong tungsten size can create problems that a new collet alone will not fix.
Cleaning and Maintenance
The original article recommends cleaning the collet with a soft brush and an appropriate solvent. That is a practical approach when the part has surface residue but is not cracked or badly worn.
Avoid using a damaged collet just because it still fits. Cracks, deformation, and heavy discoloration are signs that replacement may be the better choice.
After cleaning, let the part dry before storage or installation. Keeping small TIG consumables organized by size also helps you avoid setup mistakes.

Is It Worth the Price?
The Mtsooning 5PCS 45V44 TIG Welding Collet set is worth considering if you need several small replacement collets instead of a full torch parts kit. The value comes from the five-piece count, copper material, and support for the torch models listed in the article.
It is a smart buy for everyday use if your current setup already uses 45V44 collets and 2.4mm / 3/32 inch tungsten. It is not the best fit if you are unsure about your torch model, need a different tungsten size, or want a complete kit with cups and collet bodies.
How It Compares to Alternatives
Compared with larger TIG consumables kits, this Mtsooning set is more focused. You get replacement collets, not a full assortment of cups, collet bodies, back caps, or tungsten electrodes.
If you need a wide range of parts, a full TIG consumables kit may be better. If you only need 45V44 collets in 2.4mm / 3/32 inch size, this five-piece pack is the simpler option.
