1535-100 - Oxweld Style 1535-100 Propane Cutting Tip Internal

Precision Engineered Internal Cutting Tip for Propane Applications

The 1535-100 Internal Cutting Tip is a critical component for industrial oxy-fuel cutting operations utilizing alternative fuels such as propane or natural gas. Designed as the inner member of a two-piece tip assembly, this product features precision-machined splines that channel the preheat gas mixture effectively. Unlike single-piece acetylene tips, propane requires a specific turbulence and anchoring mechanism to maintain a stable flame front; the interaction between this internal member and the corresponding external sleeve creates the necessary recess and flow characteristics to achieve this.

Manufactured to meet or exceed OEM specifications for Oxweld style apparatus, the 1535-100 is constructed from high-quality brass and copper alloys. This ensures excellent thermal conductivity and resistance to the high reflected heat typical of heavy plate cutting. The '100' size designation indicates a large oxygen bore, suitable for cutting thicker sections of carbon steel. The seating surfaces are machined to tight tolerances to prevent gas leakage within the torch head, ensuring safety and performance consistency.

Operators utilizing this tip can expect a distinct preheat flame pattern that allows for rapid starts even on dirty or scaled plate. The separation of the internal and external parts facilitates easier cleaning and maintenance compared to solid tips. When paired with the correct outer sleeve, the 1535-100 delivers a high-velocity oxygen stream that produces smooth, square cuts with minimal top edge rounding and reduced slag adherence at the bottom of the kerf.
