0324-0109 - Victor 4-MFA-1 Rosebud Heating Tip for 100 Series Handles

Victor 4-MFA-1 Heating Nozzle (0324-0109)

The Victor 4-MFA-1 Heating Nozzle is a specialized multi-flame component engineered for medium-duty industrial heating applications. Identified by the part number 0324-0109, this nozzle belongs to the MFA-1 series, specifically designed for compatibility with Victor 100 Series torch handles, such as the 100FC. It utilizes Acetylene or Hydrogen as a fuel gas, providing a concentrated and consistent heat source essential for precision metalworking tasks.

Technically, the 4-MFA-1 is a Size 4 tip, capable of generating approximately 29,400 BTUs per hour. This thermal output is achieved through a multi-flame "rosebud" design that distributes heat evenly across a targeted area, making it superior to standard cutting tips for non-cutting thermal applications. The assembly measures 12 inches in length, offering the operator sufficient distance from the radiant heat of the workpiece while maintaining control. The nozzle features a double O-ring seal to ensure a secure, leak-proof fit within the torch handle mixer, maintaining safety standards during operation.

This heating nozzle is constructed from high-grade copper, ensuring excellent thermal conductivity and resistance to deformation under high temperatures. It is primarily utilized in fabrication shops for preheating base metals prior to welding, straightening warped steel structures, and priming surfaces. By delivering a controlled high-temperature flame, the 4-MFA-1 allows for efficient heat transfer without the risk of localized melting associated with improper tip selection. It is a critical accessory for MRO (Maintenance, Repair, and Operations) environments where medium-duty oxy-fuel heating is required.
