0333-0305 - Victor Size 3 Propane Cutting Tip 1-GPN Series

Technical Overview of the Victor 1-GPN Size 3 Cutting Tip

The Victor 0333-0305 is a Size 3, Series 1-GPN cutting tip engineered for heavy-duty industrial applications utilizing Propane or Natural Gas. As a genuine Victor component, it is manufactured to precise tolerances to ensure stable flame characteristics and optimal gas mixing. The 1-GPN series features a two-piece design consisting of a brass outer shell and a splined copper inner insert. This configuration is essential for alternate fuel gases like propane, which require a recessed flame focus to maintain ignition stability and prevent blow-offs during the preheat phase.

This specific tip is rated for cutting mild steel with a thickness of approximately 2-1/2 inches (63.5 mm). Operational specifications require a cutting oxygen pressure range of 45-50 PSIG and a fuel gas pressure of 6-10 PSIG. The total oxygen consumption is rated between 175-200 CFH, with preheat oxygen consumption ranging from 23-108 CFH depending on the flame setting. Fuel gas consumption is efficient at 14-18 CFH. The tip is designed to fit Victor "large series" equipment, including 300 Series torch handles and compatible cutting attachments such as the 2460 series.

The two-piece construction not only aids in combustion efficiency for slower-burning gases but also facilitates maintenance. The separation of the inner and outer members allows for easier cleaning of the preheat splines, ensuring consistent gas distribution. This tip is suitable for both manual hand cutting and mechanized machine cutting operations where general-purpose straight cutting is required.
