VH5 - Uniweld VH5 Propane Rosebud Heating Tip #5 for VHE-10 Elbow

Technical Overview of the Uniweld VH5 Heating Head

The Uniweld VH5 is a specialized multi-flame heating head, commonly referred to in the industry as a "rosebud," designed to facilitate heavy-duty thermal applications. Engineered for compatibility with Victor-style equipment, this specific nozzle is sized as a #5, placing it in the mid-to-high range of heat output capabilities suitable for industrial fabrication environments. It is strictly calibrated for use with alternative fuels, specifically Propane and Natural Gas, and should not be utilized with Acetylene due to the distinct pressure and withdrawal rate requirements of different fuel gases.

Structurally, the VH5 features a robust copper construction which aids in heat dissipation, preventing the tip itself from overheating during prolonged use. The multi-flame orifice configuration is designed to produce a broad, soaking heat pattern rather than a concentrated point, making it the ideal tool for preheating base metals prior to welding, post-weld heat treating, or bringing large metal sections up to temperature for bending and straightening operations. The tip is designed to thread directly onto a Uniweld VHE-10 heating elbow (or compatible Victor-style equivalent), which then connects to a standard heavy-duty torch handle.

Operators utilizing the VH5 must ensure their gas supply system is capable of sustaining the necessary flow rates. Propane heating heads typically consume significant volumes of oxygen and fuel to generate their high BTU output. The recessed face of the nozzle provides a degree of protection for the flame ports, reducing the likelihood of occlusion from molten spatter or accidental contact with the workpiece. This unit represents a critical component for MRO operations requiring efficient, large-scale thermal transfer without the cost implications of Acetylene.

Operational Specifications

When integrating the VH5 into a production line, verify that the mixing assembly (the elbow/mixer) is rated for propane service. Using this head with an acetylene mixer can lead to backfires or unstable flame characteristics. The #5 size indicates a substantial heat generation capacity, requiring appropriate safety gear, including high-shade eyewear and heat-reflective clothing, to protect the operator from the intense radiant energy produced.
