OVERVIEW

Technical Overview: MFA-4 Oxy-Acetylene Heating Head

The GENMFA-4 is a high-performance replacement heating head designed to replicate the specifications of the Victor MFA series. Engineered for use with Oxygen and Acetylene gases, this size #4 tip utilizes a multi-flame configuration to deliver a concentrated yet broad heat output, suitable for industrial metalworking applications. The assembly is constructed from high-grade copper, ensuring excellent thermal conductivity and resistance to deformation under high-temperature conditions.

This heating nozzle is specifically threaded to fit Victor-style 300 and 310 series torch handles (and compatible 300-series generic handles). It operates efficiently within a pressure range of 8-12 PSIG for Oxygen and 6-10 PSIG for Acetylene. The multi-port face design creates a stable flame pattern that maximizes BTU transfer to the workpiece, reducing the time required to reach critical temperatures for metallurgical processes.

Operators should note that this tip is strictly for use with Acetylene; use with alternate fuel gases such as Propane or Propylene requires a different tip design (typically MFN series) to prevent backfires and ensure proper combustion. The GENMFA-4 is an essential component for MRO environments requiring reliable thermal tools for maintenance, fabrication, and structural repair.

FAQ

The MFA-4 fits Victor-style 300 and 310 series torch handles, as well as compatible generic handles with the same thread pattern.

No, the MFA series is designed specifically for Acetylene. Using Propane requires an MFN series tip to ensure proper combustion and safety.

The recommended settings are typically 8-12 PSIG for Oxygen and 6-10 PSIG for Acetylene, though you should always consult the specific chart for your regulator and torch setup.

A 'rosebud' or multi-flame tip is used for applying large amounts of heat to a broad area, useful for bending, straightening, preheating, and brazing heavy materials.

No, this is a Victor-style generic replacement part designed to meet or exceed the performance specifications of the original equipment.

You should use a standard tip cleaner set. Insert the appropriate size wire into the flame ports to remove carbon buildup and slag, ensuring a clean flame pattern.

MFA tips are designed for Acetylene gas, while MFN tips are designed for alternative fuels like Propane or Natural Gas. They have different internal geometries to handle the different gas densities and burn rates.

This is the heating head (tip) only. It requires a compatible torch handle; the mixing chamber is typically integrated into the heating head assembly or the handle depending on the specific torch design, but for 300 series, the mixer is often part of the head assembly.
