0333-0268 - Victor Size 6 GPP Propylene Cutting Tip, 8-Inch Capacity

Technical Overview of the Victor 0333-0268 6-GPP Cutting Tip

The Victor 0333-0268 is a Size 6, Type GPP cutting tip engineered specifically for use with Propylene fuel gas. This consumable is a critical component for industrial oxy-fuel cutting operations requiring the ability to sever thick metal sections. The tip features a two-piece construction, consisting of a brass shell and an internal insert, which is characteristic of tips designed for alternative fuels like propylene. This design aids in the proper mixing of preheat gases and facilitates easier cleaning compared to single-piece acetylene tips. The unit is manufactured in Mexico and adheres to Victor's rigorous quality standards for gas equipment.

Performance specifications for the 6-GPP are optimized for heavy-duty applications. The tip is rated for a metal thickness cutting capacity of 8 inches (approximately 203 mm). To achieve this performance, the operator must maintain a cutting oxygen pressure range of 55-65 psig. The fuel gas pressure requirement is set between 10-15 psig. In terms of volumetric flow, the total oxygen consumption ranges from 450 to 500 cubic feet per hour (cfh), while the total fuel gas consumption is between 25 and 35 cfh. The preheat oxygen consumption varies significantly based on flame adjustment, ranging from 23 to 153 cfh. These flow rates ensure sufficient thermal energy density and kinetic force to oxidize and remove molten metal from deep kerfs.

The physical dimensions of the tip are approximately 0.8 x 0.7 x 3.2 inches, making it compatible with standard Victor-style torches designed for alternative fuels. The cutting speed for this specific tip size on 8-inch material is rated at 4 to 6 inches per minute (ipm). This relatively slow travel speed is dictated by the thermal inertia of the thick workpiece and the oxidation rate of the steel. The 6-GPP is suitable for both manual hand torches and mechanized machine cutting setups, providing versatility across different fabrication environments. It is classified under the GPP series, which denotes General Purpose Propylene, distinguishing it from high-speed or specialty tips.

Maintenance of the 0333-0268 involves regular inspection of the seating surfaces and the orifice. As a two-piece tip, the outer shell can be removed to clean the splines of the inner member, ensuring consistent preheat flame distribution. Users should verify that their regulator and hose systems are capable of delivering the required high-volume oxygen flow (up to 500 cfh) to prevent starvation during the cut, which could lead to backfires or poor cut quality.
