ESAB Model 33368 30 Amp Nozzle for Plasmarc PT-27 Plasma Torch, Pack of (5): Product Breakdown

Forge — Thu, 06 Aug 2026 10:15:51 +0000

The ESAB Model 33368 30 Amp Nozzle for Plasmarc PT-27 Plasma Torch, Pack of (5) is a consumable part used in plasma cutting. For buyers, maintenance teams, and welding support staff, the main question is not whether it is a replacement part, but whether it matches the torch family, amperage range, and cut duty you actually run on the shop floor. This draft stays focused on that practical check.

The product page indicates this is a 30 amp nozzle intended for PT-23 and PT-27 Plasmarc plasma torches. Beyond that, the important technical details that affect fit and performance should be verified against the machine manual and the torch consumable chart before purchase or installation. If a detail is not confirmed in the source material, treat it as Unknown (Verify).

Key Takeaways

This is a plasma nozzle consumable, not a universal part.
The listed amperage is 30 amp, but the correct operating range still needs verification against your torch and power source.
The source product information states PT-23 and PT-27 Plasmarc torch use.
As with any nozzle, cut quality depends on air quality, arc start condition, standoff, and wear state.
Pack quantity is five nozzles according to the source product listing.

What This Part Does

A plasma nozzle constricts and directs the plasma arc. In practical terms, it affects kerf shape, arc concentration, and edge quality. A worn nozzle can show up as wider kerf, rougher edge, harder starts, arc instability, or accelerated wear in related consumables. If your cut quality has changed, do not assume the nozzle is the only cause. Air contamination, electrode wear, damaged swirl components, incorrect stand-off, and double arcing can produce similar symptoms.

For broader root-cause checks, see the support article on plasma torch nozzle damage causes. For torch-family and consumable matching logic, the plasma drag shield compatibility guide is a useful reference point, even though this part is a nozzle and not a drag shield.

Buyer Checklist Before Ordering

Use this as a field check before you place the order or pull stock for a job:

Check torch family: Confirm the torch is PT-23 or PT-27 as listed in the source product information.
Check amperage: Confirm your application uses a 30 amp nozzle. If the machine is set up differently, the correct match is Unknown (Verify) until confirmed.
Inspect the current nozzle: Look for orifice distortion, spatter buildup, ovality, or heat damage.
Inspect related parts: Check electrode, retaining cap, swirl ring or equivalent torch components, and air passages as applicable to your torch design.
Verify cut problem symptoms: If the issue is intermittent arc transfer, poor start consistency, or excessive dross, confirm whether consumable wear is actually the cause.
Verify machine settings: Confirm air pressure, cutting speed, stand-off, and polarity per the equipment manual. Unknown (Verify) if manual data is not on hand.

Support and Troubleshooting Notes

When a nozzle is replaced too early, the real problem usually stays in the system. Use a simple inspect sequence:

1) Inspect the nozzle. Remove it and examine the orifice under good light. Check for wash-out, eccentric wear, cracks, or heavy spatter. If the opening no longer looks uniform, replacement is justified.

2) Inspect the electrode. A damaged electrode can create arc instability that looks like nozzle failure. Replace related consumables as a set when wear is obvious or when the torch manual recommends it.

3) Inspect air quality. Moisture, oil, and dirt in the air supply shorten consumable life. Verify dryer function, filter condition, and regulator behavior. If air quality has not been measured recently, it is Unknown (Verify).

4) Verify torch assembly condition. Check for damaged threads, loose fit, worn retaining parts, and signs of double arcing. If the consumable stack does not seat correctly, the nozzle will not run as expected.

5) Verify cut setup. Wrong travel speed or stand-off can destroy a new nozzle quickly. If the cut profile is poor immediately after installation, the issue may be setup rather than part quality.

Product / Parts Section

The source product information identifies the part as ESAB Model 33368 30 Amp Nozzle for Plasmarc PT-27 Plasma Torch, Pack of (5). The product summary also states use with PT-23 and PT-27 Plasmarc torches. No additional verified specs were provided in the source material, so any further material, dimensions, or certifications are Unknown (Verify).

For sourcing support, the product can be reviewed through the provided ArcWeld listing: Product not found.">ESAB Model 33368 30 Amp Nozzle for Plasmarc PT-27 Plasma Torch, Pack of (5). Use the listing as the product reference, then verify torch compatibility and amperage in the machine documentation before deployment.

How to Verify Fit in the Shop

Before issuing the part, run these checks:

Match the torch model: PT-23 or PT-27 per the source listing.
Match the consumable shape: Compare the old nozzle to the new one visually and by seating style.
Confirm the installation stack: Nozzle, electrode, and adjacent consumables should assemble without force.
Test on scrap: Make a short cut on comparable material before releasing the torch back to production.

Safety Notes

De-energize the system before changing consumables.
Do not inspect the plasma arc directly.
Wear eye and hand protection during part removal and test cuts.
Verify compressed air condition before use. Contaminated air can shorten consumable life and affect operator safety.
If the torch shows repeated double arcing or abnormal noise, stop and inspect the full torch stack before continuing.

FAQ

Is this nozzle only for the PT-27?
The source product information also states PT-23 compatibility. Verify the actual torch model and consumable chart before ordering.

Can I use this nozzle at amperage other than 30 amp?
The listing identifies it as a 30 amp nozzle. Other amperage use is Unknown (Verify) unless confirmed by the torch and power source documentation.

What causes a new nozzle to fail quickly?
Common causes include poor air quality, incorrect stand-off, damaged electrode parts, double arcing, and cutting too fast or too slow. Check the full system, not just the nozzle.

Should I replace only the nozzle?
Not always. If the electrode or other consumables are also worn, replace the worn set as a group according to the torch manual.
