60°A Brass Nozzle Buyer's Guide: MIG & Plasma Torch Nozzles for Worldwide Buyers
Table of Contentsexpand_more
A 60°A brass nozzle is a tapered, self-insulated welding torch nozzle that channels shielding gas over the weld puddle and protects the contact tip from spatter. Choose it by torch series, bore diameter (3/8 in to 5/8 in) and tip recess (flush to 1/4 in).
Definition: A 60°A brass nozzle is a 60-degree tapered, self-insulated torch nozzle, typically machined from brass, that directs shielding gas and shields the contact tip in MIG welding and plasma cutting. Bore diameter and tip recess are its two critical selection dimensions.
Leading torch OEMs such as TWECO and AMERICAN TORCH TIP build these nozzles in numbered series — 21, 22 and 23 — so a nozzle that fits one torch body will not fit another. Getting the series right matters more than any other single decision.
How does a 60°A brass nozzle work?
The 60-degree taper accelerates shielding gas toward the weld puddle, improving coverage at the arc. The self-insulated body removes the separate insulator, cutting parts count and changeover time.
Brass construction resists spatter adhesion and conducts heat away from the nozzle face. That combination extends service life in high-duty MIG and plasma applications.
Which 60°A brass nozzle type suits your application?
Three families dominate: tapered, bottleneck and conical. Each trades gas coverage against access and visibility.
- Tapered — general MIG welding; good gas coverage, moderate access.
- Bottleneck — restricted joints and deep fillets; narrow profile reaches where tapered nozzles cannot.
- Conical — plasma cutting and general fabrication; focuses gas flow for precise cuts.
60°A brass nozzle specifications at a glance
| Attribute | Typical range | Notes |
|---|---|---|
| Bore diameter | 3/8 in to 5/8 in | Larger bore = more gas coverage, less access |
| Tip recess | Flush to 1/4 in | Deeper recess protects tip; shallower improves visibility |
| Projection | 3/32 in | Nozzle-to-tip relationship on bottleneck styles |
| Insulation | Self-insulated | Some bottleneck models require separate insulator |
| Pack quantity | 2-pack | Standard for TWECO and AMERICAN TORCH TIP |
Types and applications in Worldwide markets
Worldwide fabrication, shipbuilding, pipeline and repair shops run 50 Hz and 60 Hz power supplies side by side, so torch consumables must be sourced by series and dimension rather than by region. Export buyers typically specify nozzles by OEM part number to avoid cross-market mismatch.
Plasma cutting nozzles such as the 23 Series serve plate-cutting operations, while 21 and 22 Series MIG nozzles dominate structural and general fabrication. Both are stocked for international dispatch with export documentation.
How to select a 60°A brass nozzle
- Identify your torch series — 21, 22 or 23. This is non-negotiable; series determines thread and fit.
- Match bore diameter — 3/8 in for tight access, 5/8 in for maximum gas coverage.
- Set tip recess — flush to 1/8 in for visibility, 1/8 to 5/32 in for spatter protection, 1/4 in for heavy-duty.
- Confirm insulation type — self-insulated or separate insulator (sold separately on some bottleneck models).
- Check duty cycle — high-amperage, high-duty work favours larger bore and deeper recess.
- Verify pack quantity and export terms — most nozzles ship as 2-packs; confirm incoterms and documentation for Worldwide delivery.
Product comparison: 60°A brass nozzle ladder
| Model | Series | Style | Bore diameter | Tip recess | Best for |
|---|---|---|---|---|---|
| TWECO WS21T-37 Tapered MIG Nozzle | 21 | Tapered, self-insulated | 3/8 in | 1/8 to 5/32 in | Light-duty MIG, tight access |
| AMERICAN TORCH TIP 21T-37 Tapered Nozzle | 21 | Tapered | 3/8 in | 1/8 in | Precise gas flow, arc welding |
| TWECO WS22 Bottleneck Nozzle | 22 | Bottleneck | 1/2 in | Flush to 1/8 in | Restricted joints, visibility |
| TWECO 22 Series Bottleneck Nozzle | 22 | Bottleneck | 1/2 in | 1/4 in | Heavy-duty, deep fillets |
| TWECO EL22CT62 Tapered Nozzle | 22 | Tapered, self-insulated | 5/8 in | 1/8 to 5/32 in | High-coverage MIG |
| TWECO 23 Series Conical Nozzle | 23 | Conical, self-insulated | 5/8 in | 1/8 to 5/32 in | General fabrication and repair |
| AMERICAN TORCH TIP 23-62-F Conical Nozzle | 23 | Conical, self-insulated | 5/8 in | Flush to 1/16 in | Plasma cutting, precise cuts |
Step up the ladder when duty cycle rises: move from a 3/8 in bore 21 Series nozzle to a 5/8 in bore 22 or 23 Series nozzle as amperage and spatter increase. For restricted joints, switch to a bottleneck profile rather than a larger bore.

Key takeaways
- Match torch series (21, 22 or 23) before anything else — fit is series-specific.
- Bore diameter runs 3/8 in to 5/8 in; larger bore means more gas coverage, less access.
- Tip recess from flush to 1/4 in controls spatter protection versus visibility.
- Self-insulated designs cut parts count; some bottleneck models need a separate insulator.
- 3G Electric supplies Worldwide with export documentation and technical support.
