The Tip End #P-3 Oxy/Propane DHC-2000 represents a critical component for users of the legendary DHC-2000 (formerly Henrob and Dillon) oxy-fuel torch system. Unlike standard oxy-acetylene torches that rely on high-pressure turbulent mixing, the DHC-2000 utilizes a unique low-pressure mixing chamber that delivers optimal gas utilization. This specific #P-3 tip is engineered to maximize the thermal efficiency of propane, a fuel gas often relegated to cutting or heating but transformed into a precision welding medium by the DHC system.
The geometry of the P-3 tip is calculated to maintain a stable, non-oxidizing flame even at the low 4 PSI working pressure characteristic of the Cobra/DHC line. This stability is paramount when working with sensitive metallurgies such as aluminum or cast iron, where flame chemistry can dictate the success of the weld. The tip's orifice is precision-drilled to ensure a laminar flow, reducing the noise and turbulence associated with standard torch tips while focusing the BTU output exactly where it is required.
Constructed from high-grade copper alloy, the tip offers excellent thermal conductivity, preventing the nozzle from overheating during extended duty cycles. This thermal management is essential for preventing pre-ignition or "popping" inside the tip, a common issue with inferior consumables. For industrial maintenance and fabrication professionals, the P-3 size offers a versatile range, capable of handling material thicknesses that require significant heat input without sacrificing the fine control the DHC-2000 is known for.
By optimizing for propane, this tip also presents an economic advantage, allowing for substantial operational savings over acetylene without compromising weld quality. It is an indispensable accessory for any fabrication shop leveraging the unique capabilities of the DHC-2000 system for structural repairs, automotive restoration, or intricate metal shaping.
