1600210 - Harris 1390-5N Alternate Fuel Separable Brazing Tip

Technical Overview of the Harris 1390-5N Brazing Tip

The Harris Model 1390-5N is a specialized separable brazing tip designed specifically for use with alternate fuels such as propane, natural gas, and propylene. Engineered for precision and durability, this tip features a one-piece construction utilizing high-grade tellurium copper. Tellurium copper is selected for its superior machining properties and high electrical and thermal conductivity, ensuring that the tip maintains stability over a broad BTU range during operation. This material choice significantly enhances the longevity of the tip, resisting deformation under high-heat conditions common in industrial brazing applications.

Operational Efficiency and Design

A key design feature of the 1390-5N is its counter-bored tip end. This geometric configuration is critical for maximizing flame stability and heat concentration, allowing for efficient heat transfer to the workpiece. The tip is designed to function seamlessly with a low-pressure "F" injector-type mixer, optimizing the fuel-oxygen mixture for a clean and consistent flame. The engineering behind the tip allows a single size to accommodate a wide variety of joint sizes, providing versatility for operators working on diverse assemblies without the need for constant tip changes.

Leak Prevention and Maintenance

The Harris 1390-5N utilizes a precision-machined metal-to-metal tip contact seat. This design eliminates the need for thread sealants or joint compounds, which can often contaminate the gas stream or degrade over time. The metal-to-metal seal ensures a leak-proof connection, enhancing safety and reducing gas wastage. Furthermore, the tip is engraved with the model number and tip size, facilitating easy identification in a busy workshop environment. This clear labeling aids in inventory management and ensures the correct tip is selected for the specific fuel gas and mixer setup.

Manufacturing and Specifications

Manufactured in Poland, the 1390-5N adheres to strict quality control standards. It is backed by a one-year manufacturer's warranty, attesting to its reliability and build quality. The tip is compatible with standard Harris equipment designed for alternate fuels, making it a seamless replacement or upgrade for existing setups. Its robust construction and thoughtful design make it an essential component for professionals requiring consistent brazing performance with alternate fuel gases.
