66Z33 - Victor Type 55 Size 10 Multi-Flame Heating Nozzle (Propane/Natural Gas)

Technical Overview: Victor Type 55 Size 10 Heating Nozzle

The Victor Type 55 Size 10 Heating Nozzle (SKU: ESB66Z33) is a high-performance, multi-flame heating assembly engineered specifically for use with alternative fuels such as Propane and Natural Gas. Manufactured by ESAB under the Victor brand, this nozzle is designed to deliver substantial thermal energy for heavy industrial applications including preheating, straightening, and shrinking of thick metal sections. Unlike acetylene nozzles, the Type 55 series utilizes the specific combustion characteristics of propane and natural gas to provide a soaking heat that is ideal for large surface areas.

Technically, the nozzle features a heavy-duty construction comprising a durable outer shell and a precision-drilled multi-flame tip face. It is designed to integrate directly with Victor 300 Series heavy-duty torch handles (such as the 315FC). The assembly includes an integral mixer or is designed to work with the handle's mixing system to ensure the correct oxygen-to-fuel ratio, preventing flashback and ensuring a stable flame even at high flow rates. The Size 10 designation indicates a high flow capacity, capable of generating significant BTU output required for working with heavy plate and structural members.

Operators must note that this nozzle is not compatible with Acetylene. Attempting to use acetylene with a Type 55 nozzle can result in dangerous flashbacks or equipment damage due to the different burning velocities and pressure requirements of the gases. The nozzle is optimized for the lower burning velocity of alternative fuels, utilizing a recessed tip design or specific port geometry to maintain flame stability.
