MFA-8 - Victor Style MFA-8 Rosebud Heating Tip, Size 8

Heavy-Duty Heating Performance

The GENMFA-8 Heating Head is a premium-quality, Victor-style replacement nozzle designed for industrial oxy-acetylene heating applications. Engineered to fit standard 300 and 310 series torch handles, this multi-flame "rosebud" tip is an essential tool for fabricators, boilermakers, and heavy equipment repair technicians who require rapid heat transfer for large metal components.

Optimized Multi-Flame Design

Unlike single-point welding tips, the MFA-8 features a multi-port face that produces a broad, soft, and high-intensity flame. This configuration allows for the even distribution of heat across a wider surface area, making it significantly more efficient for tasks such as preheating prior to welding, straightening bent steel structures, and hot forming. The Size 8 orifice configuration is calibrated to deliver a substantial BTU output, capable of bringing thick plate and heavy wall pipe to working temperature quickly.

Robust Construction & Compatibility

Manufactured from high-grade copper and brass, the GENMFA-8 is built to withstand the intense reflected heat generated during heavy heating operations. It features a precision-machined coupling end with double O-rings to ensure a secure, leak-free connection to the torch handle. This nozzle is specifically designed for use with Acetylene gas and requires appropriate regulator settings (typically 20-30 PSI Oxygen and 10-15 PSI Acetylene) to maintain a stable flame and prevent backfire. Users must ensure their acetylene supply is sufficient to meet the withdrawal rates of a Size 8 tip to prevent solvent withdrawal from the cylinder.

Applications

• Preheating heavy castings and plate before welding.
• Flame straightening of structural steel beams.
• Bending and forming of pipe and bar stock.
• Large-scale brazing and soldering operations.
• Removing seized nuts and bolts on heavy machinery.
