1800500 - Harris H-85-1 Oxy-Acetylene Rosebud Heating Tip Assembly

Technical Overview of the Harris H-85-1 Heating Tip Assembly

The Harris H-85-1 is a specialized heating tip assembly designed to deliver high-efficiency thermal output for industrial metalworking applications. Engineered as a cohesive unit, this model integrates the tip tube and mixer into a single assembly, streamlining the equipment setup process for operators using compatible Harris torch handles. Specifically calibrated for Oxy-Acetylene gas mixtures, the H-85-1 utilizes a multi-flame "rosebud" configuration to distribute heat evenly across a targeted surface area, making it an essential tool for processes requiring rapid thermal saturation.

Compatibility is a key feature of the H-85 series. This assembly is designed to fit the widely used Harris 43 Series torch handles (such as the 43-2), as well as other compatible medium-to-heavy duty handles in the Harris lineup. The connection mechanism features a precision-machined base with double O-ring seals, ensuring a gas-tight fit that prevents back-leakage and maintains consistent pressure during operation. The use of copper in the tip head construction aids in effective heat dissipation, prolonging the service life of the consumable even under sustained high-temperature use.

In terms of performance, the H-85-1 is categorized as a size 1 tip within the H-85 family. This designation indicates a specific flow rate and BTU output suitable for medium-duty heating tasks. Unlike single-flame welding tips, the multi-orifice design of this heating assembly allows for a broader flame profile, significantly reducing the time required to bring base metals to the critical temperatures needed for bending, straightening, or pre-weld heat treatment. Operators must ensure that their acetylene supply system can support the withdrawal rate required by multi-flame tips to prevent solvent withdrawal from the cylinder.

The assembly's robust design withstands the rigors of industrial environments, from shipyards to structural steel fabrication shops. By combining the mixer and tip, Harris minimizes the potential for mismatching components, thereby enhancing safety and operational consistency. The H-85-1 represents a reliable solution for professionals requiring precise control over heat input without compromising on power or durability.
