16K12 - Purox 4202 Series Size 6 Acetylene Cutting Tip

High-Performance Industrial Cutting

The ESAB Purox 4202 Series Acetylene Cutting Nozzle (SKU: 16K12) represents the pinnacle of gas cutting technology for heavy industrial applications. Designed specifically for use with acetylene fuel gas, this Size 6 tip is engineered to deliver clean, precise cuts on mild steel up to 6 inches in thickness. The nozzle features a one-piece copper construction which ensures optimal thermal conductivity and durability under high-heat conditions. This design philosophy not only extends the service life of the consumable but also maintains a consistent flame profile during extended operation.

Technically, the 16K12 nozzle operates within a specific pressure range to maximize efficiency and safety. It requires a cutting oxygen pressure of 60 to 70 PSIG and an acetylene pressure of 10 to 12 PSIG. At these settings, the nozzle consumes approximately 340 to 460 cubic feet per hour (CFH) of total oxygen and 22 to 28 CFH of acetylene. The resulting flame produces a kerf width averaging between 0.130 and 0.160 inches, allowing for tight tolerances in fabrication work. The cutting speed ranges from 6 to 9 inches per minute, providing a balance between throughput and cut quality.

The "Medium Preheat" designation of this nozzle is achieved through six precision-drilled preheat holes. This configuration provides sufficient thermal energy to rapidly bring the base metal to ignition temperature, making it suitable for starting cuts on heavy plates and for beveling applications where heat input must be maintained across an angled surface. Whether utilized in general-purpose hand cutting or mounted in machine cutting setups, the Purox 4202 Series ensures reliability and performance consistent with ESAB's manufacturing standards. The tip is manufactured in Mexico and adheres to strict quality control measures to ensure compatibility with Purox style torches.
