Cutting-tip numbers can look interchangeable, but the wrong series, seat, or fuel-gas design can create a poor flame and an unsafe connection. The RX WELD 3-101 Series Acetylene V-Style Cutting Torch Tips package gives you four tip sizes, 0 through 3, for compatible light- and medium-duty V-style cutting attachments. Its main advantage is having several common sizes in one compact set. Its main limitation is strict compatibility, so this review focuses on fit, included parts, safe setup, and the jobs this assortment makes sense for.
Quick Verdict
Rating: 8/10, recommended with caveats
Best For: Welders, repair shops, maintenance crews, and DIY metalworkers who already use a compatible V-style acetylene cutting attachment.
Bottom Line: This four-piece set is a convenient way to keep sizes 0, 1, 2, and 3 available for mixed cutting work. Buy it only after confirming the 3-101 series, tip seat, cutting attachment, and acetylene fuel requirements for your torch.

What Are the RX WELD 3-101 Torch Tips?
The RX WELD RXCT30123 package is a four-tip replacement and backup assortment for acetylene oxy-fuel cutting. It includes size 0, 1, 2, and 3 tips in the 3-101 series. The set does not replace the rest of your torch system, and it does not include a torch handle, cutting attachment, oxygen or acetylene regulator, hose, cleaner, or safety equipment.
The range is useful when your work changes from lighter sheet or small repair cuts to thicker plate handled within the limits of your compatible torch. Instead of buying four sizes separately, you can keep one matched series together in a small package that weighs about 7 ounces.
This is an aftermarket-style V-pattern set, not a universal nozzle kit. The listing identifies the CA 1350-90° and CA 1260-90° cutting attachments, while Victor equipment references also pair the 3-101 series with those medium- and light-duty attachment families. You should still compare your exact attachment markings and manual before ordering.
Before You Buy: Do not order by the numbers 0, 1, 2, and 3 alone. Those are tip sizes, not proof of fit. Your attachment must accept the 3-101 series seat and must be approved for acetylene use.
Who Should Buy It?
Best For
- You own a compatible CA 1350-90° or CA 1260-90° style cutting attachment that uses 3-101 acetylene tips.
- You cut several steel thicknesses and want sizes 0 through 3 available without buying each one separately.
- You need a compact spare set for a garage, service truck, farm shop, maintenance area, or small fabrication bench.
Skip If
- Your torch uses a different tip series, seat design, or cutting attachment.
- You use propane, propylene, natural gas, or another fuel gas instead of acetylene.
- You need an OEM tip, a certified material specification, or a pressure and thickness chart supplied with the package.
Fit and Compatibility
Fit is the deciding factor for this set. The product is identified as a 3-101 V-style tip assortment for light- and medium-duty acetylene cutting equipment. The listed attachments are CA 1350-90° and CA 1260-90°. A similar-looking tip from another series may have a different seat, length, mixer relationship, or gas-flow pattern.
Before buying, read the markings on your cutting attachment and the tip currently installed. Match the complete designation, not just the first or last number. You can also compare the series with the Victor/ESAB Type 101 product reference, then follow the manual for your specific torch.
Do not force a tip into a seat that feels wrong or rely on extra tightening to stop a leak. A correct tip should seat as designed with clean, undamaged contact surfaces. If the threads, nut, seat, or attachment are worn, replacing the tip alone may not correct the problem.
Build Quality and Package Details
The product listing describes a tight-sealing connection, a heat-resistant base, and controlled gas flow. Those are relevant design goals for any cutting tip, but they do not remove the need for inspection and leak testing. The exact alloy, coating, hardness, and dimensional tolerances are not published in the verified product details, so this review does not assign a specific material grade.
The listed package measures 3.7 × 3.23 × 0.94 inches and weighs 7 ounces. That makes the set easy to keep in a labeled parts drawer or service box. Store each tip where the seating surface and orifices cannot be dented, contaminated, or mixed with a different fuel-gas series.
Only the four tips are listed as included. You may need to supply a correctly sized tip cleaner, leak-detection solution approved for fuel-gas equipment, and any replacement seals or attachment parts specified by your torch manufacturer.
Cutting Range and Flame Control
Sizes 0 through 3 give you a useful progression, but the number alone does not set a universal metal-thickness limit. Cutting capacity depends on the attachment, oxygen flow, acetylene flow, hose length and diameter, regulator capacity, material condition, and the chart used for the complete torch system.
The smaller tips in this set are the logical choices for lighter cutting within the equipment chart. The larger sizes provide more capacity for heavier plate when your regulators, hoses, attachment, and cylinders can supply the required flow. Moving to a larger tip without checking the chart can cause poor preheat, excess gas use, backfire, or an unstable cut.
Clean orifices help the preheat flames stay even around the center oxygen jet. When one or more holes are partly blocked, you may see an uneven flame, a wandering kerf, slag that will not clear, or a cut that repeatedly loses penetration. Stop and inspect the tip instead of increasing pressure to compensate for a blockage.
Compatibility and Safety
Oxy-acetylene equipment can cause fire, explosion, burns, and cylinder hazards when it is assembled or operated incorrectly. Use these tips only with compatible, serviceable equipment and follow the torch, regulator, hose, cylinder, and tip instructions. Wear the shade, eye protection, gloves, clothing, and other personal protective equipment required for your work.
Inspect the tip before every use. Check the seating surface, threads, outer body, and all orifices. Do not use a tip with cracks, distorted holes, damaged threads, a burned seat, or signs that it has been dropped or overheated. Keep oil and grease away from oxygen equipment, and use reverse-flow check valves or flashback protection when your equipment instructions or workplace rules require them.
Perform the leak check and lighting sequence specified by your equipment manufacturer. For broader workplace requirements, review OSHA 29 CFR 1910.253 for oxygen-fuel gas welding and cutting. If you are not trained to set up oxy-fuel equipment, have a qualified person inspect the system and show you the correct procedure.
Pro Tip: Label each storage slot with the full tip number, such as 0-3-101 or 2-3-101. That prevents you from mixing sizes or returning a used, partly clogged tip to the clean-spare compartment.
How It Performs in Real Use
For Lighter Sheet and Repair Cuts
The smaller tips give you a controlled starting point when your torch chart calls for them. They are useful for patch work, brackets, damaged fasteners, and lighter scrap. A clean tip and steady travel speed matter more than trying to force the cut with excess pressure.
For Medium-Thickness Steel Plate
The larger tips in the assortment let you step up without changing to another product series. This is useful for plate, structural offcuts, farm repairs, and demolition work that stays inside the capacity of your light- or medium-duty torch. Confirm that your gas supply can support the required flow before installing size 2 or 3.
For Mixed Repair and Fabrication Work
A four-size set reduces downtime when one job includes several material thicknesses. You can keep the same 3-101 family while selecting the size called for by the chart. That is more practical than trying to make one worn tip handle every cut.
For Backup and Service-Truck Storage
The 7-ounce package is small enough for a service box, but the tips need protected storage. Keep them dry, clean, and separated from loose hardware. A spare set is most useful when you also carry the correct cleaner and know which size your common jobs require.
How to Use It Correctly
Shut down, isolate, cool, and depressurize the equipment as directed by its manual before changing a tip. Remove the old tip without damaging the attachment, inspect the seat, and clean away debris with an approved method. Install the selected 3-101 tip evenly and tighten it only as specified for the attachment.
After assembly, perform the prescribed leak test. Set the regulator pressures from the chart for your exact tip, material thickness, hose setup, and torch. Light and adjust the torch using the manufacturer sequence, then make a short test cut on scrap before starting critical work.
Use a purpose-made cleaner that matches each orifice. Push it gently and straight. Do not use drill bits, nails, welding wire, or an oversized cleaner because enlarging or misshaping the holes changes gas flow and can ruin the tip.
Common Mistakes to Avoid
- Buying by size number without confirming the 3-101 series and seat.
- Using an acetylene tip with propane, propylene, or natural gas.
- Guessing pressures from another torch, tip series, or hose setup.
- Overtightening a tip to compensate for a damaged or dirty seat.
- Continuing to cut after repeated backfires, popping, uneven flames, or visible tip damage.
Pros and Cons
Pros
- Includes four clearly stepped sizes: 0-3-101 through 3-3-101.
- Designed for acetylene and listed for compatible V-style light- and medium-duty attachments.
- CA 1350-90° and CA 1260-90° compatibility is clearly identified.
- Compact 7-ounce package is easy to store as a working assortment or backup set.
- Buying four sizes together can be more convenient than sourcing each tip separately.
Cons
- Limited to compatible 3-101 acetylene setups, so it will not fit every Victor-style or V-style torch.
- No verified alloy specification, warranty term, or pressure and thickness chart is included in the available product details.
- The package lists tips only, so you must supply the torch system, cleaner, and required safety equipment.
Is It Worth the Price?
The RX WELD 3-101 set is worth considering if you use several compatible tip sizes and want one ready-made assortment. Its value comes from convenience, compact storage, and coverage from size 0 through size 3. A shop that repeatedly uses only one size may get better value from buying that single tip as needed.
This is a practical aftermarket option for routine repair, maintenance, and occasional fabrication work. It is not the best fit when your purchasing policy requires OEM parts, published dimensional tolerances, a manufacturer-supplied cut chart, or a documented warranty.
How It Compares to Alternatives
Victor OEM Series 3 Type 101 tips are the clearest alternative when you want factory-branded parts and official product support. They are commonly sold one size at a time, which can be better for a shop that already knows its most-used tip but less convenient when you need a full 0-to-3 assortment.
Single-size RX WELD 3-101 packs can also make more sense when one tip wears faster than the others. Other aftermarket four-piece V-style sets may include a cleaner, but you still need to compare the exact series, attachment list, included sizes, and fuel gas. This RX WELD package makes the most sense when the four included sizes match your actual workload.
Frequently Asked Questions
What cutting attachments are these RX WELD tips listed to fit?
The product identifies CA 1350-90° and CA 1260-90° cutting attachments. Confirm the full attachment marking, 3-101 series, seat, and acetylene requirement before buying because similar-looking V-style tips are not automatically interchangeable.
Which exact tip sizes come in the package?
You get four tips: 0-3-101, 1-3-101, 2-3-101, and 3-3-101. The torch, cutting attachment, regulators, hoses, and cleaner are not listed as included.
Can you use these tips with propane or another fuel gas?
No other fuel gas is verified for this set. It is listed for acetylene, so do not use it with propane, propylene, natural gas, or another gas unless the tip and equipment manufacturers expressly approve that exact combination.
What metal thickness can sizes 0 through 3 cut?
There is no single safe thickness answer based on the tip number alone. Use the chart for your exact torch, attachment, hose, gas supply, and material because required pressures and flow can change across equipment setups.
How should you clean a 3-101 cutting tip?
Use a purpose-made tip cleaner that matches the orifice and work gently from the correct end. Do not use drill bits, nails, random wire, or an oversized cleaner because they can enlarge or distort the gas passages.
Is this a complete cutting torch kit?
No. The listed package contains four cutting tips only. You need compatible torch equipment, oxygen and acetylene supplies, regulators, hoses, and the safety components required by your setup.
What are signs that a tip should be replaced?
Replace a tip with cracked or burned surfaces, damaged threads, distorted holes, a damaged seat, or repeated performance problems that proper cleaning does not correct. Stop using the torch if you get persistent popping, backfire, leaks, or an uneven flame and inspect the complete system.
Who should skip this four-piece set?
Skip it if you cannot verify the 3-101 series and attachment fit, use a fuel gas other than acetylene, or require an OEM component. It is also unnecessary when your work uses only one tip size and you already have reliable spares.
The Bottom Line
The RX WELD RXCT30123 is a sensible four-tip assortment for buyers who can confirm a compatible 3-101 acetylene V-style cutting attachment. Its best feature is the useful size 0-to-3 range in one compact package. Skip it when your torch uses another series or fuel gas, or when you need OEM documentation and a supplied cut chart.
