0311-0240 - Victor Type 55 Multi-Flame Heating Nozzle, Size 6, Alt Fuel

Victor Professional 55 Series Multi-Flame Heating Head - Size 6

The Victor Professional 55 Series Multi-Flame Head (SKU: 0311-0240) represents a specialized solution for heavy industrial heating applications utilizing alternative fuel gases. Engineered specifically for use with Propane, Natural Gas, Propylene, and other non-acetylene fuels, this Size 6 heating nozzle is designed to deliver high-capacity thermal output for processes such as heat treating, metal straightening, and surface priming. The assembly is strictly compatible with the Victor HD 310C torch handle and necessitates the use of a 3/8-inch hose to ensure adequate gas volume and flow stability.

Technically, the Type 55 Series distinguishes itself through a robust architectural design focused on operational longevity and safety. A defining feature of this nozzle is the raised center point on the face of the head. This mechanical standoff serves a critical function: it prevents the flame orifices from being compressed or obstructed should the head come into direct contact with the plate or workpiece. By maintaining this physical separation, the design preserves the integrity of the flame cone and prevents the dangerous pressure buildups that can lead to flashbacks.

Furthermore, the internal geometry of the Type 55 incorporates an improved mixer design. This mixer is calibrated to handle the specific flow characteristics and combustion ratios of alternative fuels, which differ significantly from acetylene. The result is a heating head that offers superior resistance to sustained backfire, even under the thermal stress of continuous heavy-duty operation. The flow performance is optimized to provide a consistent, broad heat pattern necessary for bringing large metal sections to temperature efficiently. Industrial operators must note that this specific model is not compatible with acetylene gas due to the different withdrawal rates and combustion velocities involved.

In summary, the Victor 0311-0240 provides a reliable, high-performance interface for heavy heating requirements, combining Victor's legacy of gas apparatus engineering with specific safety enhancements for modern alternative fuel usage.
