0004470920 - ESAB Finemarker 1.0mm Plasma Nozzle

Precision Plasma Marking with ESAB

The ESAB 0004470920 Finemarker Nozzle is a specialized consumable designed for industrial plasma marking applications. Engineered with a precise 1.0mm orifice, this nozzle is the focal point of the Finemarker system, a process used to etch part numbers, layout lines, bend lines, and drill points onto metal plates during the fabrication process. Unlike standard cutting nozzles which focus the arc to sever material, this marking nozzle constricts the low-amperage arc just enough to discolor or score the surface metal without penetrating it.

Using genuine ESAB OEM parts is critical for automated systems where repeatability is paramount. The 0004470920 nozzle is manufactured to tight tolerances, ensuring that the gas flow and arc characteristics remain consistent from one part to the next. This consistency is vital for automated CNC tables where a failed mark can lead to identification errors downstream in the assembly process. The high-quality copper alloy construction ensures efficient heat dissipation, prolonging the life of the consumable even during long production runs.

This nozzle is compatible with ESAB's dedicated Finemarker torches and systems often found on gantry cutting machines. Whether you are marking mild steel, stainless steel, or aluminum, this 1.0mm nozzle provides the control needed for legible, permanent identification. It is an essential component for fabricators utilizing plasma systems for both cutting and marking operations.
