0311-0650 - Victor 15-A-MFA Acetylene Rosebud Heating Tip

Victor 15-A-MFA Heating Tip Overview

The Victor 15-A-MFA Heating Tip (0311-0650) is a premium-grade consumable designed for heavy-duty industrial heating applications. Engineered by Victor, a leader in gas equipment, this tip belongs to the MFA series, which is specifically calibrated for use with Acetylene gas. The "MFA" designation stands for Multi-Flame Acetylene, indicating its specialized design to produce a concentrated, high-temperature flame suitable for rapid heat transfer.

This specific model is a Size 15, which places it at the higher end of the capacity spectrum for hand-held torch applications. A size 15 tip is capable of delivering a massive amount of heat, making it essential for tasks involving thick steel plates, heavy structural members, and large pipe sections. The multi-flame "rosebud" configuration ensures that the heat is distributed evenly over the target area while maintaining the intensity required to bring metal to working temperatures quickly.

Technical Specifications and Compatibility

The 15-A-MFA is constructed from high-quality copper and brass, ensuring durability and resistance to the extreme reflected heat often encountered during operation. It is designed to fit Victor Heavy-Duty Torch Handles, commonly known as the 300 Series (e.g., 315FC). Users must ensure they are using a handle with sufficient flow capacity to support a tip of this size.

Operational Considerations

Due to the high gas volume requirements of a Size 15 tip, operators must pay close attention to their acetylene supply. The withdrawal rate must not exceed 1/7th of the cylinder's capacity per hour to prevent the withdrawal of acetone from the cylinder. For a tip of this magnitude, manifolding multiple acetylene cylinders is often necessary to maintain safe and consistent flow rates. This tip is strictly for heating and should not be confused with cutting tips; it does not feature a central oxygen jet for oxidation.

Whether you are preheating for welding, flame straightening distorted components, or bending heavy bar stock, the Victor 15-A-MFA provides the thermal output and reliability professional fabricators demand.
