0558005217 - ESAB PT-37/38/39 Plasma Torch Gas Swirl Baffle 30-80A

Precision Gas Flow Control for ESAB PT Series Torches

The ESAB Gas Baffle (SKU: 0558005217) is a precision-engineered component designed to manage the fluid dynamics of plasma gas within the torch head. Specifically calibrated for the PT-37, PT-38, and PT-39 torch models, this baffle functions effectively within an amperage range of 30 to 80 Amps. In plasma cutting systems, the gas baffle—often referred to as a swirl ring—plays a pivotal role in constricting the arc and cooling the consumables. By inducing a specific swirl pattern to the gas flow as it surrounds the electrode and exits through the nozzle, this component ensures the plasma column remains centered and stable, which is essential for achieving high-quality cuts with minimal bevel.

Manufactured in the United States, this OEM part adheres to ESAB's rigorous tolerance standards. The physical dimensions of 1.75 x 1.35 x 1.4 inches ensure a perfect interference fit within the torch head assembly, preventing gas leakage and ensuring that the full volume of air or nitrogen is utilized for the cutting process. The material composition is selected to withstand the intense thermal radiation and conductive heat generated during the plasma process, resisting deformation that could lead to turbulent flow and arc instability. For industrial maintenance and repair operations (MRO), utilizing genuine ESAB baffles guarantees that the torch operates within its design parameters, maintaining the integrity of the electrical isolation and gas distribution systems.

Failure to replace a worn or damaged gas baffle can lead to a cascade of issues, including rapid electrode wear, nozzle orifice erosion, and poor cut edge quality. This 30-80 Amp baffle is optimized for the mid-range power settings typical of the PT-38 torch series, balancing the velocity of the gas to protect the electrode emitter while providing sufficient force to blow molten metal from the kerf. It is a critical spare part for any facility utilizing ESAB plasma cutting equipment.
