0004450620 - ESAB Quattrojet Propane/NG Machine Cutting Nozzle Size 3 (200mm)

Precision Engineering: ESAB Quattrojet Propane/NG Nozzle

The ESAB Quattrojet Nozzle (Size 3, 200mm) represents the upper echelon of machine cutting consumables. For professional welders and fabricators utilizing automated oxy-fuel gantries or track burners, the choice of nozzle dictates the quality of the cut edge and the thermal input into the base material. This nozzle is specifically calibrated for Propane and Natural Gas (NG), featuring internal geometries that optimize the preheat flame for these slower-burning gases. This ensures a rapid start and a sustained, powerful cutting jet that maintains stability even at high travel speeds.

The "Quattrojet" nomenclature refers to ESAB's high-speed divergent bore technology. Unlike standard straight-bore tips, high-speed nozzles expand the cutting oxygen stream as it exits the tip, increasing velocity to supersonic levels. This results in a narrower kerf, less slag adhesion, and a squarer edge. The 200mm length of this specific SKU (0004450620) offers distinct advantages in heat management and physical clearance, allowing the cutting torch to operate effectively even when navigating complex fixtures or uneven plate surfaces.

Maintenance and longevity are also addressed in the design. The nozzle is typically chrome-plated or treated to resist the adhesion of molten spatter, which is common during the piercing process. This keeps the preheat holes clear and the cutting stream unobstructed for longer periods. For operations transitioning from Acetylene to Propane/NG to improve safety and reduce cylinder handling, the ESAB Quattrojet is the perfect companion to maintain high productivity levels.
