16K13 - Oxweld 4202 Propane Cutting Tip - Size 10 (10-Inch Capacity)

Technical Overview of the Oxweld 4202 Series Size 10

The ESAB Oxweld 4202 Series Cutting Tip (Part Number 16K13) is a high-capacity nozzle engineered for industrial cutting operations utilizing Propane or Natural Gas. As a Size 10 tip, it is designed to handle substantial material thicknesses, typically rated for cutting steel plate in the range of 10 inches (approx. 250mm). This makes it an essential component for heavy fabrication, demolition, and scrap processing where deep penetration and stable arc characteristics are not applicable, and thermal cutting is the primary method.

Unlike single-piece acetylene tips, the 4202 series features a two-piece construction consisting of an outer shell and an inner insert. This design is critical for alternative fuels; the splined gap between the insert and shell creates a focused, high-velocity preheat flame that anchors firmly to the tip face. This ensures that despite the lower burning velocity of propane or natural gas, the steel reaches ignition temperature rapidly. The internal geometry is precision-machined to maintain a laminar oxygen stream, preserving cut quality even at the extended standoff distances often required for thick plate cutting.

The tip seats are manufactured to exact Oxweld specifications, ensuring a leak-proof metal-to-metal seal with compatible torch heads (C-32, C-66, etc.). The chrome-plated outer sheath helps reflect radiant heat during prolonged heavy cuts, reducing the risk of tip overheating and extending the consumable's service life. Operators should ensure their regulator settings are adjusted for the high flow rates required by a Size 10 orifice to prevent starvation and backfires.
