2290H-1 - Uniweld 2290H-1 Harris Style Propane Heating Tip Size 1

Technical Overview of the Uniweld 2290H-1 Heating Tip

The Uniweld 2290H-1 is a specialized heavy-duty heating tip engineered to provide thermal performance equivalent to the Harris 2290-1H. Designed specifically for alternate fuel gases such as Propane, Natural Gas, and Propylene, this tip features a multi-flame "rosebud" configuration that delivers a high volume of heat for industrial applications. Unlike acetylene tips, the 2290H-1 is designed with specific port geometry and a recessed face to stabilize the flame of slower-burning alternate fuels, ensuring consistent combustion and minimizing the risk of flashback or flame lift-off during operation.

This Size 1 tip represents the entry-level size in the heavy-duty 2290H series, yet it is capable of generating significant BTU output suitable for heating medium-to-heavy sections of steel. The tip is manufactured from a solid copper shell, a material chosen for its exceptional thermal conductivity. This construction allows the tip to dissipate reflected heat rapidly, protecting the internal integrity of the nozzle and extending its service life even under continuous high-temperature use. The tip is designed to thread onto a compatible tip tube (such as the Harris or Uniweld 2393 tube), which in turn connects to a heavy-duty mixer (like the E-43) and torch handle (43-2 series).

Operational parameters for the 2290H-1 require appropriate oxygen and fuel gas pressures to maintain a neutral flame and achieve maximum efficiency. Because propane and natural gas have different stoichiometric requirements than acetylene, the use of T-grade hoses is mandatory to prevent hose degradation. The tip is ideal for applications requiring a broad soak heat, such as preheating weldments to prevent cracking, straightening structural members, bending pipe, and removing scale or rust. Users must ensure their gas supply system, particularly the fuel gas withdrawal rate, is sufficient to support the flow demands of this multi-flame orifice.

In summary, the Uniweld 2290H-1 offers a robust solution for fabricators utilizing alternate fuels. Its precise machining and durable copper alloy construction ensure reliable performance in demanding environments like shipyards, steel mills, and heavy fabrication shops. It serves as a direct replacement for OEM Harris tips, providing a cost-effective alternative without compromising on quality or safety standards.
