Victor 6-MFA-1 Multi-Flame Heating Nozzle, Size 6

Get the Heat You Need with the Victor 6-MFA-1 Rosebud

When you are stuck with a bent frame, a seized bearing race, or a piece of steel that just won't cooperate, you need heat—and you need it fast. The Victor 6-MFA-1 Heating Nozzle is the go-to "rosebud" for welders and fabricators running Victor 100 Series torch handles. Unlike a cutting torch which focuses heat to pierce, this multi-flame head is designed to soak heat into the metal efficiently, allowing you to bend, straighten, or preheat materials without damaging the surface. Whether you are in an automotive body shop, a farm repair center, or a light fabrication facility, this nozzle turns your standard torch handle into a powerful heating tool.

The Size 6 tip is a perfect middle-ground for medium-duty work. It pumps out nearly 60,000 BTUs per hour, giving you enough thermal punch to bring steel to a cherry-red temperature quickly, but it is still manageable enough for precise control on smaller parts. The 12-inch length is a feature you will appreciate after a few minutes of work; it keeps your hand far enough away from the hot zone so you don't cook your gloves while you are trying to heat a bracket. It runs on Acetylene (or Hydrogen), providing that intense, concentrated heat that propane tips sometimes struggle to match on localized spots.

Using the 6-MFA-1 is straightforward, but it demands respect. Because it draws a significant volume of gas to feed its multiple flame ports, you need to make sure your Acetylene tank is large enough to handle the flow. Starving a rosebud is a recipe for popping and overheating. Once set up correctly with a neutral flame, this nozzle runs quiet and hot, making tasks like priming heavy plate for welding or shrinking stretched metal a breeze. It is a genuine Victor part, meaning the threads are clean, the seats seal tight, and the flame pattern is consistent right out of the box.

Common Applications:

• Straightening: Correcting warped flanges or bent structural members.
• Preheating: Bringing base metals up to temperature before welding to prevent cracking.
• Loosening: Expanding rusted nuts or seized pins for easier removal.
• Forming: Heating flat bar or rod for bending into custom shapes.
