21852 - ESAB PT-24 2-Hole Gas Swirl Ring

Technical Overview of the ESAB 21852 Swirl Baffle

The ESAB 21852 Swirl Baffle is a precision-engineered component designed exclusively for the PT-24 plasma cutting torch. In plasma cutting systems, the swirl baffle (often referred to as a swirl ring or gas distributor) plays a pivotal role in the fluid dynamics of the cutting process. It sits between the electrode and the nozzle, channeling the plasma gas into a high-velocity vortex. This swirling action forces the gas to move radially and tangentially, creating a centrifugal force that pushes the cooler, un-ionized gas to the outer walls of the nozzle bore while the hot, ionized plasma core remains centered.

This specific model features a 2-hole configuration. The number and angle of the holes are calculated to provide the exact gas velocity and swirl pitch required for the PT-24's operating amperage range. By maintaining a stable gas vortex, the baffle ensures the electric arc remains constricted and centered, which is vital for achieving square cut edges and minimizing dross. Furthermore, the efficient gas flow aids in the convective cooling of both the electrode and the nozzle, significantly extending the service life of these downstream consumables.

Manufactured to ESAB's strict OEM tolerances, the 21852 baffle is made from high-temperature resistant, non-conductive materials capable of withstanding the extreme thermal environment inside the torch head without deforming. Replacing a damaged or clogged swirl baffle is a standard maintenance procedure that restores the aerodynamic integrity of the plasma stream.
