2290-4H - Uniweld 2290-4H Harris Style Propane Heating Tip #4

Unleash Maximum Heat with the Uniweld 2290-4H

The Uniweld 2290-4H is a powerhouse heating tip designed for industrial professionals who require immense thermal output for heavy-duty applications. Modeled after the popular Harris style, this #4 size heating head is engineered specifically for use with alternative fuels like Propane and Natural Gas. By utilizing these gases, operators can achieve substantial cost savings compared to acetylene while still generating the high BTUs necessary for working with thick steel plates and heavy castings.

With a staggering heat output range of 400,000 to 820,000 BTU per hour, the 2290-4H is capable of bringing large metal workpieces up to temperature rapidly. This makes it an indispensable tool for preheating prior to welding, straightening warped structural beams, or bending large-diameter pipes. The multi-flame design, often referred to as a "rosebud," distributes heat evenly across a wide surface area, preventing hot spots and ensuring uniform thermal soak.

Compatibility is key with the 2290-4H. It is designed to fit Uniweld tip elbows such as the 2310, 2316, and 2328, as well as comparable Harris style mixers and elbows. Due to the high volume of gas required to sustain its massive flame, it is critical to use a 3/8-inch internal diameter hose. Smaller hoses may restrict flow, leading to flame starvation or overheating of the tip. Whether you are in a shipyard, a structural steel fabrication shop, or a heavy equipment repair facility, the Uniweld 2290-4H delivers the reliable, high-intensity heat you need to get the job done efficiently.
