MFA-1-4 - MFA-1 Size 4 Oxy-Acetylene Rosebud Heating Tip for Victor 100 Series

Technical Overview of the MFA-1-4 Heating Head

The Generic MFA-1-4 Heating Head is a precision-engineered aftermarket replacement component designed to function seamlessly with Victor® 100 Series medium-duty torch handles. This unit is part of the MFA-1 series, specifically calibrated for Oxy-Acetylene gas mixtures. It features a multi-flame configuration, commonly referred to as a "rosebud," which is essential for applications requiring high heat input over a distributed surface area rather than a focused point.

Fabricated from high-grade copper and brass, this heating nozzle is built to withstand the intense thermal cycles associated with industrial heating tasks. The #4 tip size offers a balanced heat output suitable for medium-duty applications, such as preheating weldments, straightening warped steel, and bending pipe or bar stock. The base of the tip is machined with tight tolerances and includes dual O-rings to ensure a secure, leak-proof seat within the torch handle mixer.

Operators should note that this specific model is designed strictly for Acetylene gas. The internal geometry of the MFA series is optimized for the flame propagation rate of acetylene; using alternative fuels like Propane or Propylene with this tip can result in flame instability or overheating. This component is an ideal stock replacement for MRO inventories supporting fabrication shops, automotive repair centers, and general maintenance departments utilizing standard Victor-style medium-duty oxy-fuel equipment.
