OVERVIEW

Victor 0311-0540 12-A-MFA Multiflame Heating Tip & Elbow Overview

The Victor 0311-0540 12-A-MFA Multiflame Tip & Elbow is a premium industrial heating component designed for heavy-duty fabrication and maintenance applications. As part of the renowned Victor MFA series, this nozzle assembly is engineered specifically for use with Acetylene gas, leveraging the high flame temperature and heat transfer properties of the fuel to deliver exceptional thermal performance. The "12" designation indicates a large orifice size, capable of generating massive BTU output required for heating thick steel plates, large diameter pipes, and structural members.

This assembly features a multi-flame "rosebud" design, which distributes heat evenly across a wider surface area compared to single-point cutting or welding tips. This distribution is critical for processes such as preheating prior to welding, post-weld heat treatment, straightening warped steel, and bending heavy metal components. The integrated elbow configuration provides the necessary angle to keep the operator's hand at a safe distance from the radiant heat while allowing for ergonomic positioning during prolonged use.

Constructed from high-quality brass and copper, the 12-A-MFA is built to withstand the rigors of shipyard, construction, and heavy manufacturing environments. It is designed to interface seamlessly with Victor's heavy-duty torch handles, such as the 300 Series or HD 310C, ensuring a secure connection and optimal gas flow. Industrial MRO professionals rely on this specific SKU for its reliability and the consistent flame characteristics that Victor equipment is known for. Proper pressure settings are essential for safe operation; a tip of this size typically requires substantial gas volume, so ensuring your regulator and hose setup can supply the necessary SCFH is vital for preventing flashback and maintaining a stable flame.

Whether used for shrinking a fitting, bending a beam, or bringing a casting up to temperature, the Victor 0311-0540 stands as a definitive tool for thermal manipulation in the metalworking industry.

FAQ

The 'A' in the model number indicates it is designed specifically for Acetylene gas.

This tip is designed for heavy-duty handles, typically the Victor 300 Series or HD 310C handles.

No, this is a multi-flame heating nozzle (often called a rosebud) used for heating, bending, and straightening, not for cutting.

This is a size 12 tip, which is a large size intended for heavy heating applications.

The product is described as a Tip & Elbow assembly. In the MFA series, the tip often threads onto the elbow/mixer assembly. This SKU typically represents the complete nozzle assembly ready to attach to the handle.

No, MFA tips are designed for Acetylene. For Propane or Natural Gas, you should use MFN series tips.

While specific conditions vary, a size 12 MFA tip generally requires Oxygen pressures around 50-60 PSIG and Acetylene pressures around 12-15 PSIG. Always consult the specific Victor tip chart for safety.

Size 12 tips consume a high volume of acetylene. Drawing too much gas too quickly can withdraw acetone from the cylinder, damaging equipment and creating safety hazards. Manifolding cylinders may be necessary.
