Victor Size 12 MFA Acetylene Heating Nozzle

Get the Heat You Need with Victor MFA

When you are staring down a piece of cold 1-inch plate that needs to be bent, or a warped beam that needs straightening, you need serious heat, and you need it fast. That is where the Victor 0311-0649 12-A-MFA Heating Tip comes into play. This is a classic "rosebud" style tip designed strictly for acetylene, giving you that intense, hot flame that only oxy-acetylene can provide. If you are running a Victor 300 series torch handle (the big heavy-duty ones), this tip screws right on and turns your cutting torch setup into a powerful heating machine.

The "Size 12" on this tip means it is a beast. It puts out a massive amount of heat, perfect for preheating heavy castings before welding or getting stubborn metal red-hot for bending. Unlike cutting tips that focus a stream of oxygen to slice metal, this multi-flame adapter (MFA) spreads the heat out through multiple orifices. This allows you to soak the heat into the metal quickly without melting it away, giving you the malleability you need to work the steel. It is an essential tool for any fabricator, millwright, or structural welder who deals with heavy iron.

Durability is key in any shop, and Victor doesn't disappoint. The 12-A-MFA is built tough with a heavy copper shell that withstands the reflected heat from the work surface. The threads are solid, and the seating surface is designed to seal up tight so you don't have to worry about leaks. Whether you are shrinking a stretched panel or heating a rusted nut the size of a fist, this tip delivers consistent performance.

Remember, this tip is for Acetylene only. Do not try to run propane or natural gas through it—those gases require different injector styles (like the MFN series). Stick to acetylene, set your pressures correctly for the high flow this size 12 tip demands, and you will have the thermal power to tackle the toughest heating jobs in the shop. Add the Victor 0311-0649 to your kit and stop struggling with undersized tips that just can't keep up with the thickness of your material.
