0330-0008 - Victor 1-101 Size 5 Heavy Duty Acetylene Cutting Tip

Technical Overview of the Victor 1-101 Size 5 Cutting Tip

The Victor 0330-0008 is a Size 5 cutting tip from the renowned 1-101 series, specifically engineered for heavy-duty oxy-acetylene cutting operations. This component is manufactured from high-grade copper, a material selected for its superior thermal conductivity, which helps maintain the tip's structural integrity under the intense heat reflected from heavy plate cutting. The one-piece design integrates both preheat and cutting oxygen paths into a solid copper body, ensuring a stable flame and minimizing the risk of flashback compared to two-piece designs often used with alternate fuel gases.

Technically, the Size 5 orifice is calibrated to handle a substantial material thickness of 5 inches (approximately 127 mm). To achieve optimal performance, the manufacturer specifies a cutting oxygen pressure range of 40 to 45 PSIG (or up to 50 PSIG depending on specific conditions) and a preheat oxygen pressure of 10 to 22 PSIG. The acetylene fuel gas should be regulated between 7 and 13 PSIG. Operators should note that exceeding 15 PSIG with acetylene is unsafe. Under these parameters, the tip supports a travel speed of 6 to 8 inches per minute, balancing thermal input with kerf removal efficiency.

This tip is designed to interface with Victor's heavy-duty torch series, commonly known as the 300 Series (including handles like the 315FC with cutting attachments or ST series straight torches). The seating surface is precision-machined to ensure a gas-tight seal, preventing leaks that could compromise safety or cut quality. The 1-101 series is strictly for acetylene gas; attempting to use this tip with propylene, propane, or natural gas will result in poor preheat performance and potential equipment damage due to the different combustion velocity requirements of those gases.

In industrial MRO environments, the 0330-0008 is a critical consumable for fabrication shops dealing with structural steel, heavy equipment repair, and demolition. Its ability to maintain a focused cutting stream over a 5-inch depth makes it indispensable for processing thick sections where plasma or mechanical cutting may not be feasible. Regular maintenance, including the use of appropriate tip cleaners, is recommended to maintain the laminar flow of the cutting oxygen stream.
