0333-0403 - Victor 4-3-GPN Propane/Natural Gas Cutting Tip, Size 4

Industrial Grade Propane & Natural Gas Cutting Performance

The Victor 0333-0403, also known as the 4-3-GPN Cutting Tip, is a high-performance consumable designed specifically for general purpose hand and machine cutting applications. Engineered by Victor, a leader in gas equipment, this tip is part of the renowned Series 3 line, ensuring compatibility with standard Victor 300 series torch handles and cutting attachments. The 'GPN' designation indicates its optimization for General Purpose Natural gas and Propane, making it an essential component for industrial environments where these alternative fuels are preferred over acetylene for their cost-effectiveness and availability.

This Size 4 tip boasts a substantial cutting capacity, capable of severing steel up to 3 inches (76mm) in thickness. The internal geometry of the tip is constructed using a two-piece design, which is characteristic of high-quality alternative fuel tips. This design features a splined brass inner member and a heavy-duty copper outer shell. The separation allows for easier cleaning and maintenance compared to single-piece acetylene tips, as the outer shell can be removed to access the splines where carbon buildup or slag may accumulate. This feature significantly extends the service life of the consumable in rigorous industrial settings.

Operational parameters are critical for achieving the best cut quality. The 4-3-GPN is rated for a cutting speed of 8 to 11 inches per minute, providing a balance between speed and precision. It requires a cutting oxygen pressure range of 45 to 50 PSIG and a fuel gas pressure of 8 to 12 PSIG. Adhering to these specifications ensures a stable preheat flame and a powerful, non-turbulent cutting stream that produces clean edges with minimal slag adhesion. Whether utilized in a manual hand torch for demolition and fabrication or mounted on a machine torch for automated shape cutting, this tip delivers consistent, reliable thermal cutting performance.

Manufactured in Mexico to Victor's stringent quality standards, the 0333-0403 ensures safety and reliability. The robust construction withstands the high heat and physical demands of heavy fabrication shops, scrap yards, and construction sites. By utilizing propane or natural gas, operators can achieve deep cuts with a softer preheat flame that reduces the risk of melting the top edge of the cut, a common issue with hotter burning fuels on thick plate.
