OVERVIEW

Get the Heat You Need with the Victor 4-MFA Rosebud

When you have a bent frame to straighten, a large casting to pre-heat, or a surface that needs priming, a standard cutting tip just won't cut it. You need the soaking heat of the Victor 4-MFA Heating Nozzle (0323-0250). Known in the field as a "rosebud," this size 4 tip is a workhorse for welders and fabricators who rely on Acetylene for their heating applications. It attaches quickly and securely to your existing Victor 300 Series torch handle, turning your cutting setup into a powerful heating tool in seconds.

The 4-MFA is built to last. It features a heavy-duty one-piece design that can take the abuse of a busy shop environment. The multi-flame head produces a wide, soft, yet intense heat pattern that wraps around pipes or spreads across plates, allowing you to bring metal up to temperature quickly and evenly. This is essential for tasks like heat treating, where temperature consistency is key, or straightening, where you need localized heat to relax the metal's grain structure.

Safety and ease of use are built right in. The nozzle uses a double O-ring seal that seats perfectly in the torch handle, so you don't have to worry about gas leaks at the connection. The 12-inch length gives you good reach, keeping your hands away from the intense heat radiating off the steel. Whether you are working in a fabrication shop, on a pipeline, or in heavy equipment repair, the Victor 4-MFA gives you the thermal power you need to bend, shape, and prep steel efficiently.

Key Applications:

  • Straightening: Correcting warped flanges, beams, and structural members.
  • Pre-heating: Preparing thick plate or castings for welding to prevent cracking.
  • Priming: Drying off moisture or burning off contaminants before fabrication.
  • Bending: Heating pipe or bar stock for manual forming.

FAQ

The 4-MFA nozzle is designed to fit Victor 300 Series Torch Handles, such as the 300FC.

No, the MFA series is designed specifically for Acetylene or Hydrogen. For Propane or Natural Gas, you would need a UN or MZN series nozzle.

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

This is a multi-flame heating head (rosebud) used for heat treating, straightening, priming, and pre-heating metal.

Yes, the 4-MFA features an individual spiral mixer to ensure proper gas blending and flow characteristics.

The total length of the nozzle is 12 inches.

Yes, because this is a high-flow heating tip, you must ensure the withdrawal rate does not exceed 1/7th of the acetylene cylinder's capacity per hour to strictly avoid drawing acetone into the regulator and torch.

The Victor 4-MFA is a one-piece heating nozzle.
