35665 - ESAB PT-15XL 340A Oxygen Plasma Nozzle (Reverse Flow)

Genuine ESAB 35665 340A Oxygen Nozzle for PT-15XL

Maximize the potential of your automated cutting table with the ESAB 35665 Nozzle, a premium consumable designed for the PT-15XL plasma torch. This nozzle is rated for 340 Amps, placing it in the upper echelon of heavy-plate cutting capabilities. It is specifically engineered for Oxygen (O2) plasma cutting, a process that delivers the smoothest edges and fastest travel speeds on carbon steel. Whether you are processing structural steel, heavy machinery parts, or shipbuilding components, this nozzle provides the arc constriction necessary to slice through thick materials with precision and minimal heat-affected zones.

The ESAB 35665 is a "Reverse Flow" nozzle, a specification that refers to the direction of gas flow and the internal geometry required by the torch head. It is crucial to match the nozzle type to your specific PT-15XL setup to prevent gas turbulence and ensure a stable arc. The nozzle acts as the final focusing lens for the plasma jet; its orifice diameter and shape determine the energy density of the cut. ESAB utilizes high-grade copper alloys and advanced machining techniques to produce nozzles that resist heat deformation and erosion, extending the service life of the consumable even under the punishing conditions of 340-amp operation.

Using the correct nozzle is about more than just fit; it is about performance. At 340 amps, the thermal stress on torch components is immense. The ESAB 35665 is designed to facilitate efficient heat transfer to the torch's water-cooling system. A compromised or non-OEM nozzle can lead to overheating, which not only destroys the nozzle but can also damage the electrode and the torch body itself. By choosing genuine ESAB consumables, you are protecting your investment in the PT-15XL system and ensuring consistent cut parameters shift after shift.

Operators will appreciate the consistency provided by fresh ESAB nozzles. A sharp, well-defined nozzle orifice produces a stiff, columnar arc that clears molten metal efficiently, resulting in dross-free cuts that require little to no secondary grinding. When the cut quality starts to degrade—manifesting as rounded top edges or varying bevel angles—it is time to swap in a new 35665 nozzle. This simple maintenance step restores the torch to factory-level performance, ensuring your high-amperage oxygen cutting remains efficient, accurate, and profitable.
