0324-0111 - Victor 8-MFA-1 Rosebud Heating Tip for 100 Series Handles

Victor 8-MFA-1 Heating Nozzle (0324-0111)

The Victor 8-MFA-1 Heating Nozzle is a premium multi-flame heating head designed for industrial professionals who require reliable and intense heat output for metalworking applications. Known commonly as a "rosebud" tip, this nozzle is engineered to fit Victor 100 Series torch handles, making it an essential accessory for medium-duty oxy-fuel outfits. With a tip size of 8, it is capable of generating approximately 117,600 BTUs per hour, providing the thermal energy necessary for efficient heat treating, metal straightening, and priming tasks.

This nozzle is specifically calibrated for use with Acetylene and Hydrogen fuel gases. It is critical to note that this tip is not compatible with alternate fuels such as Propane or Natural Gas; using incorrect fuels can damage the equipment and pose safety risks. The 8-MFA-1 features a multi-flame design that distributes heat over a wider surface area compared to standard welding tips, preventing localized melting while ensuring the workpiece reaches the desired temperature uniformly. This makes it particularly effective for bending steel bars, preheating weldments to prevent cracking, or removing stubborn, rusted fasteners through thermal expansion.

Safety is paramount when operating high-output heating nozzles. Due to the significant volume of gas required to sustain the 117,600 BTU output, operators must adhere to the "1/7th rule" for acetylene withdrawal. This rule states that you should not withdraw more than one-seventh of an acetylene cylinder's capacity per hour. For the 8-MFA-1, the withdrawal rate often exceeds the capacity of a single standard cylinder, meaning that manifolding multiple cylinders is frequently required to operate this nozzle safely and efficiently. Failure to manifold can result in acetone withdrawal from the cylinder, which causes unstable flames and equipment damage.

The nozzle measures 12 inches in length, providing a safe working distance between the intense heat of the flame and the torch handle. This ergonomic design helps reduce operator fatigue and heat exposure during prolonged use. Whether you are working in structural steel fabrication, automotive repair, or general industrial maintenance, the Victor 0324-0111 offers the durability and performance expected from the Victor brand.
