The ESAB 16K17 is a size #7 cutting tip from the 4203 series, specifically engineered for use with Propane and Natural Gas fuel sources. This nozzle is designed to be compatible with Purox style torch handles and attachments, offering a direct replacement for OEM specifications. The defining characteristic of this component is its one-piece solid copper construction. Utilizing hard-drawn, electrolytic tough pitch copper, the nozzle offers superior thermal conductivity compared to brass or tellurium copper alloys, allowing it to run cooler and resist the adhesion of spatter even during prolonged cutting operations.
Internal gas flow dynamics are optimized through a triple swaging process. This technique creates gas passages that are mirror-smooth, minimizing friction losses and turbulence within the tip. The internal angles are radiused to ensure laminar flow of the preheat gases and the cutting oxygen stream. This non-turbulent flow is critical for maintaining a cylindrical oxygen stream over a greater distance, which directly correlates to cleaner cut faces, sharper top edges, and reduced slag accumulation at the bottom of the kerf. The #7 size orifice is calibrated for general purpose cutting, providing a medium preheat intensity sufficient for beveling applications and piercing plate steel.
The 4203 series is designed with longevity in mind. The preheat passages are machined deep and parallel to the central axis. This geometric feature permits the face of the nozzle to be dressed (filed flat) to remove damage or obstruction without altering the flame characteristics or gas ratios. This re-dressability significantly extends the operational life of the consumable. The base of the tip features conical seating surfaces, which facilitate self-centering during installation and ensure a metal-to-metal gas-tight seal within the torch head, preventing backfires and leaks.
