0004470898 - ESAB Finemarker Gas Baffle for PT-36 Torch

Technical Overview of the ESAB Gas Baffle Finemarker (0004470898)

The ESAB 0004470898 Gas Baffle is a specialized consumable component engineered for the Finemarker assembly, typically utilized in conjunction with the PT-36 plasma torch on automated gantry systems. In the context of plasma marking, the gas baffle plays a pivotal role in fluid dynamics, specifically controlling the distribution and swirl velocity of the plasma gas. Unlike standard cutting baffles designed for high-amperage material severance, this Finemarker baffle is optimized to constrict the arc at lower amperages, allowing for surface etching and character marking without penetrating the base material.

Manufactured to ESAB's stringent OEM specifications, this component ensures dimensional accuracy and material integrity. The baffle is constructed from high-performance, heat-resistant composites capable of withstanding the thermal cycling inherent in rapid marking operations. It sits within the torch head assembly, directing the gas flow around the electrode and through the nozzle orifice. A compromised or worn baffle can lead to turbulent gas flow, resulting in an unstable arc, double arcing, or indistinct markings. For industrial MRO professionals maintaining ESAB m3 Plasma systems or similar setups utilizing the Finemarker tool, replacing this baffle at recommended intervals is essential for preserving the longevity of the torch head and ensuring consistent marking quality.

Integration of the 0004470898 baffle is straightforward for technicians familiar with the PT-36 architecture. It is designed to seat perfectly within the retaining cap assembly, ensuring a gas-tight seal and proper alignment of the consumable stack. By maintaining the correct gas swirl, the baffle also aids in cooling the electrode and nozzle, indirectly contributing to the lifespan of surrounding consumables. This part is strictly for the marking configuration and should not be used for standard plasma cutting operations.
