Victor Size 4 MFA-1 Acetylene Heating Nozzle

Get Concentrated Heat with the Victor 4-MFA-1 Heating Tip

When your fabrication or repair job calls for serious heat, a standard welding tip just won't cut it. Enter the Victor 4-MFA-1 Heating Tip Assembly (0311-0599), your go-to solution for turning your medium-duty torch into a heating powerhouse. Designed specifically for Acetylene gas, this "rosebud" style tip features multiple flame ports that work together to deliver a concentrated, high-temperature zone. Whether you are preheating a steel plate before welding to prevent cracking, bending a stubborn piece of flat bar, or loosening a rusted nut on a piece of heavy machinery, the 4-MFA-1 gives you the thermal output you need to get the job done quickly.

This tip is built for the welder who uses a Victor 100 Series handle (like the 100FC). You don't need to drag out the heavy-duty barrel torch for every heating task; simply swap out your cutting attachment or welding nozzle for this heating assembly, and you are ready to go. The Size 4 rating means it is perfect for light-to-medium heating applications. It provides enough BTUs to heat up metal rapidly but is small enough to offer great control, preventing you from overheating surrounding areas or damaging sensitive components nearby. The flame stability is exactly what you expect from Victor—consistent, clean, and resistant to popping when set correctly.

Durability is key in the shop, and the 4-MFA-1 is constructed from high-quality copper to withstand the harsh environment of welding and fabrication. The multi-flame face is designed to resist clogging and wear, ensuring a long service life even with daily use. Remember, this tip is for Acetylene only—using it with propane will not work and can be dangerous. By adding this heating tip to your kit, you expand the versatility of your torch setup, allowing you to tackle bending, straightening, shrinking, and brazing tasks with professional ease. It’s an essential accessory for any welder looking to maximize the utility of their Victor medium-duty outfit.
