Upgrading your industrial heating apparatus with the 2290-H series translates directly into measurable operational improvements. We have engineered this nozzle to address the most common pain points experienced in high-volume metalworking facilities. From reducing fuel consumption to minimizing operator fatigue through efficient heat transfer, every aspect of this tool is designed to enhance your bottom line.
Accelerated Preheating: The optimized internal gas mixer design channels fuel with minimal turbulence, creating a highly focused flame that penetrates thick metals rapidly.
Enhanced Operator Safety: The robust one-piece architecture significantly mitigates the risk of dangerous flashbacks, providing peace of mind during continuous, high-intensity operations.
Reduced Downtime: By utilizing high-density copper alloys, the nozzle resists thermal degradation, meaning fewer replacements and longer uninterrupted production cycles.
Streamlined Inventory: Compatibility with multiple alternate fuel gases means your facility can consolidate its consumable inventory, simplifying procurement and storage.
Managing operational expenses is a critical priority for any large-scale fabrication facility. The 2290-H heating nozzle is specifically engineered to maximize the thermodynamic potential of cost-effective alternative fuel gases, including propane, natural gas, and propylene. By moving away from more expensive traditional fuels without sacrificing performance, your operation can realize significant cost savings.
Achieves a staggering heat output of over 1,000,000 BTUs per hour, ensuring that even the most massive steel structures reach target temperatures rapidly.
The precision-engineered flutes ensure an optimal oxygen-to-fuel ratio, resulting in a clean, complete combustion that minimizes wasted gas and reduces atmospheric emissions within the workshop.
Delivers a consistent, high-velocity flame that maintains its integrity even in drafty, open-air environments like shipyards.
We understand that overhauling your entire inventory of welding and heating equipment is a massive, often unjustifiable capital expense. Therefore, the 2290-H series is designed with universal integration in mind. It serves as a direct, drop-in upgrade for your existing hardware ecosystem, allowing you to enhance performance with minimal disruption.
Features an industry-standard 1/2" - 25 (M) thread connection, ensuring a secure, leak-free seal with a wide array of existing equipment.
Flawlessly compatible with mainstream torch handles such as the Harris 43-2, 63, V-315-C, and K-43, eliminating the need for proprietary adapters.
Pairs perfectly with E3-43 and F-43 mixers, allowing your procurement team to source this high-performance nozzle without disrupting your current supply chain of handles and mixers.
Industrial environments are unforgiving. Equipment is routinely dropped, exposed to extreme thermal shock, and subjected to continuous, grueling use. The 2290-H heating nozzle is built to survive and thrive in these exact conditions. Its heavy-duty, one-piece construction is a deliberate design choice to eliminate the weak points found in multi-part assembled nozzles.
Machined from a single block of high-thermal-conductivity copper alloy, ensuring uniform heat dissipation and preventing the tip from melting or deforming under its own massive heat output.
The absence of brazed joints or threaded sub-components means there are zero points of failure for gas leaks, drastically extending the operational lifespan of the tool.
The rugged exterior easily withstands the physical impacts common in heavy metalworking, reducing the frequency of your replacement cycles and lowering long-term maintenance costs.
No two heating jobs are exactly alike. A localized repair on a cast iron block requires a vastly different thermal approach than preheating a massive steel I-beam for structural welding. To accommodate the diverse needs of a modern fabrication plant, the 2290-H series is available in a comprehensive matrix of sizes, ensuring you always have the exact tool for the task.
Available in a complete range from Size 1H to Size 5H, providing granular control over your thermal application.
Smaller sizes offer precise, concentrated heat for localized straightening or bending, minimizing the heat-affected zone on sensitive components.
The largest sizes unleash the full 1,000,000+ BTU potential, blanketing massive surface areas with intense heat for rapid, uniform preheating prior to heavy structural welding.
In a bustling, dimly lit shipyard or a fast-paced manufacturing floor, clarity and ease of use are paramount. Misidentifying a heating tip can lead to suboptimal performance or, worse, severe safety hazards. We have engineered the 2290-H series to be as user-friendly as it is powerful, ensuring that your technicians can work confidently and efficiently.
Each nozzle features deeply engraved, high-contrast markings denoting the exact model and size, remaining legible even after months of exposure to soot and high temperatures.
This clear identification system empowers shop floor workers to instantly select the correct tool for the specific job, eliminating guesswork and preventing dangerous mismatches with gas pressures.
The standard hex-base design allows for swift, secure installation and removal using standard wrenches, minimizing setup time and keeping your workforce focused on the task at hand.
The true value of the 2290-H heating nozzle is realized in the field, where time is money and performance is non-negotiable. This tool is not designed for light hobbyist work; it is a heavy-duty implement forged for the most demanding industrial sectors. It empowers your workforce to tackle monumental tasks with confidence and efficiency.

To assist your procurement and engineering teams in making an informed decision, we have compiled a list of the most commonly asked technical questions regarding the 2290-H heating nozzle series. These answers provide deeper insights into the operational capabilities and maintenance requirements of the product.
No. The 2290-H series is explicitly engineered for alternative fuel gases such as Propane, Natural Gas, Propylene, Butane, and Methane. Using Acetylene with this specific multi-flame heating tip design poses a severe safety risk, including the potential for dangerous flashbacks and equipment destruction. Always ensure you are using the correct fuel gas.
The operating pressure varies significantly depending on the specific size of the nozzle being utilized. For the larger sizes, such as the 4H and 5H, the oxygen pressure requirement typically ranges from 50 to 110 PSIG. It is crucial to consult the specific flow chart for the exact size to ensure optimal flame characteristics and prevent gas starvation.
The primary advantage of the one-piece construction is its extremely low maintenance requirement. Because there are no internal threads or brazed joints to fail, standard maintenance is limited to keeping the gas orifices clean. We recommend using a dedicated tip cleaner of the appropriate size to gently remove any carbon buildup or slag from the flutes, ensuring a consistent, balanced flame.
This nozzle features a standard 1/2" - 25 (M) thread connection, which is fully compatible with industry-standard heavy-duty handles, including the 43-2, 63, V-315-C, and K-43 models. You will need to use an appropriate mixer, such as the E3-43 or F-43, to connect the nozzle to the handle securely.
The massive heat output is achieved through a combination of large, precision-drilled gas orifices and optimized internal flow dynamics. When paired with the correct high-flow mixer and supplied with adequate gas volumes (often requiring manifolded cylinders for continuous operation), the nozzle efficiently combusts large quantities of fuel, converting it directly into intense, usable thermal energy.
