0331-0017 - Victor 3-101 Size 4 Acetylene Cutting Tip (3 Inch Capacity)

Technical Overview of the Victor 3-101 Size 4 Acetylene Cutting Tip

The Victor 0331-0017 is a Size 4 cutting tip from the renowned 3-101 Series, engineered specifically for medium-duty oxy-acetylene cutting applications. Manufactured from a single piece of high-grade copper, this tip is designed to withstand the rigorous thermal cycles associated with industrial metal cutting while maintaining structural integrity and orifice precision. The 3-101 series geometry is optimized for use with Victor 100 Series cutting attachments, such as the CA1350 and CA1260, as well as compatible medium-duty handles.

Technically, the Size 4 orifice configuration allows for a substantial cutting capacity of approximately 3 inches (76 mm). To achieve optimal cut quality and slag ejection, the manufacturer specifies a cutting oxygen pressure range of 40 to 50 PSIG. The preheat oxygen requirement falls between 6 and 17 PSIG, while the fuel gas (acetylene) should be regulated to 5 to 10 PSIG. Adhering to these pressure parameters is critical for maintaining a neutral preheat flame and a laminar cutting stream, which directly influences the kerf width and the squareness of the cut face.

The one-piece copper design provides superior thermal conductivity compared to brass or multi-piece alternatives, aiding in cooler tip operation and reducing the risk of flashback. The tip features precision-drilled preheat ports that ensure an even distribution of the preheat flame around the cutting jet, facilitating rapid starts and consistent travel speeds of approximately 9 to 12 inches per minute on 3-inch plate. This specific SKU is strictly for use with Acetylene gas; utilizing alternative fuel gases with this tip design will result in improper flame characteristics and potential safety hazards.

Industrial professionals rely on the Victor 3-101 series for its balance of performance and durability. Whether utilized in manual hand-cutting scenarios or machine-cutting setups compatible with the 3-101 form factor, this tip delivers reliable service. Regular maintenance, including tip cleaning with appropriate wire cleaners, will extend the service life of the orifice and maintain the integrity of the gas stream.
