0004450294 - ESAB IAD Series Internal Cutting Tip 40-60mm

Precision Internal Nozzle for Heavy Plate Cutting

The ESAB 0004450294 is a specialized Internal Nozzle from the IAD series, engineered to deliver high-performance oxy-fuel cutting capabilities for material thicknesses ranging from 40mm to 60mm. In the realm of industrial machine cutting, the integrity of the nozzle bore and the precision of the seating surfaces are paramount. This component acts as the core of the cutting assembly, directing the cutting oxygen stream with exacting velocity and turbulence control to ensure a clean, exothermic reaction through the workpiece.

Manufactured to ESAB's rigorous OEM standards, this internal nozzle features a concentric design that ensures perfect alignment within the outer cap or retaining nut. This alignment is critical for maintaining a stable preheat flame ring and a centered cutting stream, which directly correlates to the squareness of the cut edge and the minimization of the heat-affected zone (HAZ). The 40-60mm range specification indicates that the internal geometry—specifically the throat length and exit diameter—is optimized to maintain stream coherence through plates of this substantial gauge.

Operators of automated cutting gantries and mechanized torches rely on the IAD series for its consistency. Unlike generic aftermarket replacements, which may suffer from micro-imperfections leading to stream divergence, this genuine ESAB part maintains a tight laminar flow. This results in faster cutting speeds, reduced gas consumption, and significantly less post-cut machining or grinding. The nozzle is constructed from high-thermal-conductivity alloys that dissipate heat rapidly, reducing the risk of flashback and prolonging the service life of the consumable even under high-duty-cycle conditions.

Whether utilized in structural steel fabrication, shipbuilding, or heavy equipment manufacturing, the ESAB 0004450294 ensures that your cutting parameters remain stable. It is an essential consumable for maintenance teams looking to restore their cutting machines to factory-level performance specifications.
