0004485802 - ESAB PT-36 Air Curtain Bushing 0004485802

Genuine ESAB Replacement for Precision Plasma Systems

The ESAB 0004485802 Bushing Air Curtain is a critical component designed for the maintenance and repair of high-performance automated plasma cutting systems, specifically those utilizing the PT-36 torch platform and m3 Plasma systems. In the realm of mechanized plasma cutting, the air curtain serves a vital role: it creates a barrier of air (or sometimes water, depending on the configuration) around the arc. This barrier is essential for suppressing the noise generated by the high-velocity plasma jet, containing hazardous fumes, and in some applications, allowing for underwater cutting to minimize heat distortion and glare.

This specific bushing acts as a mechanical interface and spacer within the air curtain assembly. Its primary function is to maintain concentricity between the torch body and the outer shroud components. Without a properly seated and intact bushing, the air curtain may become misaligned. Misalignment can lead to uneven airflow, which disrupts the shielding effect, potentially causing turbulent cuts, increased noise levels, or even damage to the torch consumables due to improper cooling or debris ingress. Manufactured to ESAB's exacting OEM specifications, this part ensures that your expensive plasma system operates within its designed tolerances.

For industrial MRO procurement, selecting genuine OEM parts like the 0004485802 guarantees material compatibility and dimensional accuracy. Generic substitutes in high-precision plasma torches can often lead to premature failure or subtle performance drops that affect cut quality over time. This bushing is engineered from durable materials capable of withstanding the thermal cycles and environmental conditions typical of a heavy-industrial cutting table. Whether you are performing routine preventative maintenance or repairing a crashed torch, this bushing is the correct specification for restoring the air curtain assembly to full functionality.

Installation is straightforward for qualified maintenance personnel familiar with the PT-36 breakdown. By replacing worn or cracked bushings, you protect the longevity of the entire torch head and ensure consistent, high-quality production results.
