1535-80-COMPLETE - Oxweld Style 1535-80 Propane Cutting Tip - Heavy Duty

Technical Overview: Generic 1535-80 Propane Cutting Tip

The Generic 1535-80 is a high-capacity cutting tip engineered for industrial oxy-fuel cutting applications utilizing Propane or Natural Gas. Designed as a direct aftermarket replacement for the Oxweld 1535 series, this tip features a two-piece construction essential for alternative fuel gases. The internal brass spline is precision-machined to retard the flame velocity of propane, ensuring a stable, high-temperature preheat flame necessary for piercing and maintaining the cut on heavy sections.

This specific model is a Size 80, calibrated for an extensive cutting range of approximately 8 to 12 inches (200mm to 300mm) of mild steel. This makes it suitable for heavy scrapping, demolition, and ingot cutting where deep penetration and substantial oxygen flow are required. The tip geometry is optimized to maintain a coherent oxygen jet over long distances, ensuring clean kerf walls even at maximum depth.

Durability is enhanced through a full chrome-plated finish. In high-heat environments typical of heavy plate cutting, the chrome surface reflects radiant heat, keeping the tip cooler than bare copper alternatives. Additionally, the smooth chrome surface resists the adhesion of molten slag and spatter, simplifying maintenance and prolonging the service life of the consumable. The tip seats are machined to tight tolerances to ensure leak-free compatibility with standard Oxweld-style torch heads, including C-32, C-66, and compatible machine torches.

Operators should ensure their gas supply system (regulators and hoses) is capable of delivering the high volume of oxygen and fuel gas required for a Size 80 tip to prevent starvation and backfires. Proper pressure settings are critical for optimal performance and safety.
