0387-0062 - Victor 8-MFA Professional Heating Nozzle, Size 8, 300 Series

Heavy-Duty Multi-Flame Heating Performance

The Victor 8-MFA Heating Nozzle (SKU: 0387-0062) is a professional-grade component engineered for industrial fabrication, structural steel work, and heavy repair applications. Designed to interface seamlessly with Victor 300 Series and 300FC Series torch handles, this size 8 nozzle utilizes a multi-flame configuration to deliver a substantial heat output of approximately 117,600 BTU per hour. This high thermal transfer capability makes it an essential tool for pre-heating thick plate prior to welding, straightening bent structural members, and heat-treating large metal components.

Constructed from high-quality copper and brass, the 8-MFA is built to withstand the rigors of daily industrial use. The assembly features an individual spiral mixer which optimizes the fuel gas and oxygen mixture, ensuring a stable, high-intensity flame. It is specifically calibrated for use with Acetylene and Hydrogen fuel gases. Operators must note that the high withdrawal rate required to sustain 117,600 BTU/hr typically exceeds the safe withdrawal capacity of a single standard acetylene cylinder (1/7th rule). Consequently, manifolding of cylinders is essential to maintain safe and efficient operation, preventing solvent withdrawal and ensuring flame stability.

With a length of 12 inches, the nozzle allows the operator to maintain a safe working distance from the intense radiant heat generated during operation. The MFA series represents the standard for heavy-duty oxy-acetylene heating, providing the reliability and performance required in shipyards, rail yards, and heavy fabrication shops. Proper gas pressure settings and flow rates are critical for maximizing the lifespan of the tip and ensuring process safety.
