The ESAB 1646-1715 (QTRW64180STL) is a one-piece AFN-type acetylene fuel nozzle designed for heavy-duty, straight-line cutting. It is manufactured from hard-drawn, electrolytic, tough-pitch copper and features a triple-swaged interior with rounded internal angles to facilitate non-turbulent gas flow and precise metal fabrication.
Features
One-piece solid copper construction provides maximum cooling and heat resistance
Triple-swaged interior ensures mirror-smooth gas passages for efficient flow
Rounded internal angles eliminate turbulence for clean, smooth cuts with minimal kerf
Closely spaced preheat ports around the cutting orifice provide high concentration of preheat flames
Long, parallel preheat passages allow the nozzle to be redressed without affecting performance
Conical seats provide instant alignment and tight seals to prevent leaks at the nozzle nut
Electrolytic tough-pitch copper construction outlasts standard copper alloy nozzles
