1502214 - Harris 6290-1.5VVCP High-Speed Propylene Machine Cutting Tip

Harris Model 6290-1.5VVCP Machine Cutting Tip Overview

The Harris Model 6290-1.5VVCP is a specialized machine cutting tip engineered to deliver optimal performance when using propylene as a fuel gas. Part of the renowned Harris 6290 family, this tip utilizes a sophisticated two-piece construction method that separates the preheat maintenance from the cutting oxygen stream, allowing for precise flame characteristics tailored to alternate fuels. The internal shell is machined from high-quality brass to ensure consistent gas flow and thermal stability, while the outer shell features a robust electroless nickel plating. This plating is not merely aesthetic; it provides critical protection against radiant heat and prevents molten spatter from adhering to the tip, a common issue in high-duty cycle machine cutting applications.

Technically, the 1.5VVCP is designed with a .034 cup depth and specific internal geometry to accelerate the cutting oxygen stream, classifying it as a high-speed tip. This design results in a narrower kerf width compared to standard general-purpose tips, which directly translates to material savings and reduced gas consumption over the life of the project. The increased cutting speed capability allows operators to traverse the workpiece faster, thereby reducing the total heat input into the base metal. Lower heat input is crucial for minimizing thermal distortion, particularly in large-scale fabrication and shipbuilding where dimensional accuracy is paramount. The tip is calibrated for a cutting range of approximately 2 to 4 inches (50-100mm), making it a versatile choice for medium-to-heavy plate processing.

The "P" designation in the model number explicitly indicates its optimization for Propylene, a fuel gas that offers a higher heat release in the secondary flame compared to acetylene, making it highly effective for machine cutting where preheat dwell times can be minimized. This tip fits all standard Harris machine torches designed for the 6290 seat style, ensuring seamless integration into existing industrial setups. Manufactured in Poland to strict quality standards, the 6290-1.5VVCP represents a convergence of durability, efficiency, and precision engineering for the modern industrial fabricator.
