60°A Brass Nozzle Buyer's Guide: MIG & Plasma Torch Nozzles for Worldwide Supply
Table of Contentsexpand_more
A 60°A brass nozzle is a tapered or conical welding-torch nozzle that channels shielding gas over the weld puddle and shields the contact tip from spatter. For Worldwide buyers, selection comes down to three numbers: bore diameter (3/8 in to 5/8 in), tip recess (flush to 5/32 in), and torch series compatibility (21, 22 or 23 Series).
What is a 60°A brass nozzle?
A 60°A brass nozzle is a consumable torch nozzle with an approximately 60-degree tapered or conical profile, machined from brass for thermal conductivity and spatter release. It is the front-end component that shapes shielding-gas flow and protects the contact tip in MIG welding and plasma cutting.
In practice, the "60°A" descriptor maps onto the tapered and conical nozzle families sold by AMERICAN TORCH TIP and TWECO — the two brands 3G Electric stocks across its 21, 22 and 23 Series nozzle range.
How does a 60°A brass nozzle work?
The nozzle sits over the contact tip and forms an annular passage for shielding gas. The taper or cone concentrates gas flow toward the arc, displacing atmospheric oxygen and nitrogen that would otherwise cause porosity.
Brass is chosen because it resists spatter adhesion better than steel and dissipates heat quickly, extending consumable life in high-duty-cycle fabrication. Self-insulated designs eliminate a separate insulator, while bottleneck and standard designs may require one sold separately.
Which 60°A brass nozzle type suits your application?
Three families cover most Worldwide welding and cutting work:
- Tapered nozzles — narrow profile for restricted joints and out-of-position MIG welding.
- Bottleneck nozzles — extended reach for deep grooves and pipe roots; often used with a separate insulator.
- Conical nozzles — broad gas coverage for general fabrication, repair and plasma cutting.
60°A brass nozzle specification table
| Attribute | Typical range | Notes |
|---|---|---|
| Bore diameter | 3/8 in to 5/8 in | Larger bore = wider gas coverage |
| Tip recess | Flush to 5/32 in | Deeper recess = more tip protection |
| Projection | 3/32 in typical | Bottleneck styles only |
| Profile angle | ~60° taper/cone | Defines gas-focus behaviour |
| Insulation | Self-insulated or separate | Confirm before ordering |
| Pack quantity | 2-pack standard | Per 3G Electric listings |
How to select a 60°A brass nozzle
- Identify your torch series. 21, 22 and 23 Series nozzles are not interchangeable; confirm the torch model first.
- Match bore diameter to the joint. 3/8 in for tight access, 1/2 in for general work, 5/8 in for broad coverage.
- Set tip recess for the process. 1/8 to 5/32 in recess suits most MIG; flush to 1/16 in suits plasma cutting.
- Confirm insulation design. Self-insulated nozzles simplify changeovers; bottleneck styles may need a separate insulator.
- Check duty cycle and spatter load. High-amperage, high-spatter work justifies brass conical nozzles over tapered.
- Verify export and voltage context. Worldwide buyers should confirm 50 Hz / 60 Hz power supply compatibility for the welding power source, not the nozzle itself.
Product comparison: 60°A brass nozzle ladder
| Model | Series | Profile | Bore diameter | Tip recess | Insulation |
|---|---|---|---|---|---|
| TWECO WS21T-37 Tapered MIG Nozzle | 21 Series | Tapered | 3/8 in | 1/8 to 5/32 in | Self-insulated |
| American Torch Tip 21T-37 Tapered Nozzle | 21 Series | Tapered | 3/8 in | 1/8 in | Self-insulated |
| TWECO WS22 Bottleneck Nozzle | 22 Series | Bottleneck | 1/2 in | Flush to 1/8 in | Insulator separate |
| TWECO 22-50 Bottleneck Nozzle | 22 Series | Bottleneck | 1/2 in | 1/4 in | Insulator separate |
| TWECO EL22CT62 Tapered Nozzle | 22 Series | Tapered | 5/8 in | 1/8 to 5/32 in | Self-insulated |
| TWECO 23 Series Conical Nozzle | 23 Series | Conical | 5/8 in | 1/8 to 5/32 in | Self-insulated |
| American Torch Tip 23-62-F Conical Nozzle | 23 Series | Conical | 5/8 in | Flush to 1/16 in | Self-insulated |
Step up the ladder when duty cycle rises: start with a 3/8 in tapered nozzle for light fabrication, move to a 1/2 in bottleneck for deeper joints, and finish with a 5/8 in conical nozzle for high-amperage, high-spatter production welding or plasma cutting.

Key takeaways
- Match torch series (21, 22, 23) before anything else — nozzles are not interchangeable.
- Bore diameter drives gas coverage; tip recess drives tip protection.
- Confirm self-insulated vs insulator-separate designs to avoid changeover delays.
- 3G Electric supplies Worldwide with export documentation and technical sizing support.
