16K10 - Purox 4202 Series Acetylene Cutting Tip Size 5

Technical Overview of the ESAB Purox 4202 Series Cutting Tip

The ESAB Purox 4202 Series Acetylene Cutting Tip, identified by SKU 16K10 for Size 5, is a premium consumable engineered for industrial oxy-fuel cutting applications. This nozzle is manufactured from hard-drawn, electrolytic, tough pitch copper, a material selected for its superior thermal conductivity and resistance to deformation under high-temperature conditions. Unlike multi-piece tips or those made from standard copper alloys, the one-piece construction of the 4202 series ensures a robust and long-lasting service life, capable of withstanding the rigors of continuous machine and hand cutting operations.

Technically, the 4202 series is characterized by its medium preheat capability. This design feature incorporates a specific arrangement of preheat orifices—typically six—that provide sufficient thermal energy to maintain the ignition temperature of the steel substrate without causing excessive melting of the top edge. This balance makes the Size 5 tip particularly effective for beveling applications where flame stability and heat control are critical. The internal geometry of the tip is swaged to precise tolerances, optimizing the laminar flow of the cutting oxygen stream. This results in a clean kerf with minimal slag adhesion, reducing the need for post-cut machining or grinding.

Compatibility is a key specification for the 16K10 model. It is designed to seat perfectly in all Purox brand cutting torches, ensuring a gas-tight seal and safe operation. The tip is rated for use strictly with Acetylene gas, leveraging the high flame temperature of this fuel for rapid piercing and fast cutting speeds. Operators should adhere to standard pressure settings for the 4202 series to maximize efficiency and safety. The Size 5 designation indicates its specific bore diameter and cutting capacity range within the series, making it a versatile choice for mid-range plate thicknesses commonly encountered in fabrication shops and heavy industry.
