M6-4 - Victor Style Size 4 Acetylene Cutting Tip (M6 Series)

Industrial Grade M6-4 Acetylene Cutting Tip

The M6-4 Acetylene Cutting Tip is a robust, general-purpose consumable designed for professionals requiring reliable performance in oxy-fuel cutting operations. Modeled after the industry-standard Victor 1-101 series, this tip is engineered to fit a wide range of Victor-style cutting attachments and straight torches, making it a versatile addition to any fabrication shop or field service truck. The "M6" designation typically correlates to the medium-duty to heavy-duty tip geometry widely used in structural steel fabrication, scrap cutting, and maintenance repair operations.

Constructed from high-quality copper alloy, this one-piece tip is specifically optimized for acetylene gas. Acetylene tips require a specific internal geometry to manage the high flame velocity and heat output of the fuel. The single-piece design ensures maximum thermal conductivity, keeping the tip cool during prolonged cuts to prevent overheating and potential flashbacks. The tip features a precision-drilled central oxygen orifice sized for "Size 4" applications, which generally correlates to a cutting capacity of approximately 3 inches (75mm) of mild steel. Surrounding the cutting jet are multiple preheat orifices that provide a stable, concentric ring of fire, ensuring rapid preheating of the base metal and sustained ignition during the cut.

Proper maintenance of the seating surfaces is critical for safety. The M6-4 utilizes a standard conical seat that mates metal-to-metal with the torch head. Users should ensure the torch head is free of carbon and debris before installation to prevent gas leaks. This tip is ideal for manual cutting operations where edge quality and kerf width control are important. It is recommended to operate this tip within the manufacturer's suggested pressure ranges—typically 40-50 PSI for cutting oxygen and 5-10 PSI for acetylene—to achieve the cleanest cuts and prolong the life of the consumable.
