OVERVIEW

Victor 15-MFA Heating Nozzle: Technical Overview

The Victor 15-MFA Heating Nozzle (SKU: 0323-0262) is a premium-grade, multi-flame heating head engineered for heavy-duty industrial applications. Designed to function exclusively with Acetylene and Hydrogen fuel gases, this nozzle is a critical component for professionals requiring precise and intense heat distribution. The MFA series is characterized by its one-piece construction, which integrates an individual spiral mixer. This design element is pivotal for ensuring a consistent and safe mixture of oxygen and fuel gas, resulting in a stable flame profile even under demanding conditions.

Mechanically, the nozzle is built to withstand the rigors of industrial environments. It features a robust brass coupling nut equipped with a built-in snap ring, facilitating a secure and durable connection to the torch handle. The interface utilizes a double O-ring seal mechanism, which provides a superior gas-tight seal compared to metal-to-metal connections, significantly reducing the risk of leaks and backfires. With a physical length of 17.5 inches, the 15-MFA is designed to keep the operator at a safe distance from the radiant heat of the workpiece, enhancing safety during prolonged use.

Compatibility is specific and critical for this component. The Size 15 MFA nozzle is designed for use with Victor HD 310C series torch handles. Operators must ensure they are using a 3/8-inch (9.5mm) hose to supply the necessary volume of gas required for a tip of this magnitude. A crucial operational parameter for the Size 15 tip is the acetylene withdrawal rate. Due to the high volume of gas consumption, users must adhere to the "1/7th rule," ensuring that the withdrawal rate does not exceed 1/7th of the cylinder's contents per hour. Failure to do so may require the use of an acetylene manifold system to supply sufficient volume safely.

This nozzle is not compatible with propane or natural gas; attempting to use these alternative fuels can result in flame instability and potential equipment damage. The MFA series represents Victor's commitment to quality in oxy-fuel equipment, providing reliable performance for heat treating, straightening, and priming tasks in fabrication, shipbuilding, and heavy equipment repair sectors.

FAQ

The Victor 15-MFA is designed specifically for use with Victor HD 310C series torch handles.

No, the MFA series is engineered for Acetylene or Hydrogen gas only. For propane or natural gas, you must use the Victor MFN series nozzles.

Due to the high flow requirements of a Size 15 tip, a 3/8-inch (9.5mm) hose is required to ensure safe and adequate gas delivery.

This heating nozzle has an overall length of 17.5 inches, providing excellent reach and operator safety.

A 'rosebud' or multi-flame tip is used to apply large amounts of heat to a broad area quickly, ideal for bending, straightening, and pre-heating metal.

Large heating tips like the Size 15 consume acetylene very rapidly. You must not withdraw more than 1/7th of a cylinder's capacity per hour to prevent dangerous acetone withdrawal. You may need to manifold cylinders to use this tip safely.

Yes, the Victor 15-MFA is a one-piece nozzle that includes an individual spiral mixer built into the assembly.

It is best suited for heavy-duty applications such as heat treating, priming, straightening bent steel, and pre-heating thick materials before welding.
