OVERVIEW

Technical Overview of the Victor 4-MFA-1 Heating Nozzle

The Victor 4-MFA-1 (SKU: 0387-0071) is a specialized multi-flame heating nozzle engineered for medium-duty industrial applications. Designed to interface seamlessly with Victor 100FC series torch handles, this nozzle utilizes a Type MFA-1 configuration, specifically calibrated for Acetylene or Hydrogen fuel gases. The assembly features a robust copper and brass construction, ensuring high thermal conductivity and resistance to deformation under prolonged high-temperature exposure.

Technically, the Size 4 designation indicates the orifice array and flow capacity, which yields an approximate heat output of 29,400 BTU per hour. This thermal output is achieved through a multi-flame "rosebud" design that distributes the flame focus over a wider surface area compared to single-point welding tips. This distribution is critical for processes requiring uniform temperature elevation, such as normalizing, annealing, or pre-heating prior to welding. The 12-inch length of the assembly allows the operator to maintain a safe standoff distance while manipulating the thermal zone.

The nozzle's internal geometry is optimized to maintain stable flame characteristics and prevent flashback, provided it is operated within the recommended pressure parameters for Size 4 MFA tips. It is essential to note that this nozzle is not compatible with alternate fuels like Propane or Natural Gas, which require different injector designs (typically Type MFN). The 4-MFA-1 represents a precise balance of portability and power, enabling effective heat treatment capabilities on standard medium-duty torch platforms found in general fabrication and maintenance environments.

FAQ

The Victor 4-MFA-1 is designed to fit Victor 100 Series torch handles, including the popular 100FC models.

No, the MFA-1 series is designed specifically for Acetylene or Hydrogen gas. For Propane or Natural Gas, you would typically need a Type MFN or UN series nozzle designed for alternate fuels.

The Size 4 MFA-1 nozzle produces approximately 29,400 BTUs per hour, depending on gas pressure settings.

It is used for heavy heating applications such as straightening bent metal, heat treating, priming, and pre-heating materials before welding.

The total length of the Victor 4-MFA-1 nozzle assembly is 12 inches.

No, this is a heating nozzle (often called a rosebud). It is designed to apply heat, not to cut metal.

The nozzle is constructed from industrial-grade copper and brass to ensure heat resistance and durability.

The MFA-1 nozzle for the 100 series handle typically includes its own mixing mechanism or is designed to work directly with the handle's mixer, but always verify your specific handle's requirements. For the 100FC, it attaches directly.
