Victor 2-1-101 Acetylene Cutting Tip Size 2 (Clamshell)

Technical Specifications: Victor 2-1-101-CS (0387-0136)

The Victor 0387-0136 is a Size 2 cutting tip from the 1-101 series, the industry standard for general purpose manual cutting with Acetylene. This tip is precision-manufactured to deliver a stable preheat flame and a coherent high-velocity oxygen stream, essential for producing square faces and clean top edges on carbon steel. The "CS" designation denotes retail-ready clamshell packaging, ensuring the seating surfaces and orifices remain factory-pristine until deployment.

Operational Parameters

Designed for the 1-inch to 1.5-inch (25-38mm) cutting range, the Size 2 tip requires specific pressure settings for optimal performance. Typically, oxygen pressure should be set between 35-40 PSIG for cutting, while Acetylene fuel pressure is generally maintained between 3-5 PSIG. Operators should always consult the specific cut charts for their torch handle to fine-tune these settings based on hose length and regulator flow characteristics. The 1-101 geometry is optimized for Acetylene's burning velocity, ensuring flash resistance and flame stability even during aggressive piercing operations.

Compatibility and Construction

This tip features a one-piece copper construction. Unlike two-piece tips used for alternate fuels, the single-piece design maximizes heat transfer away from the tip face, reducing the risk of overheating and flashback. The internal geometry is swaged to reduce turbulence in the gas flow, resulting in a smoother cut surface that requires less secondary grinding. The 0387-0136 is compatible with all Victor 300 Series torch handles and cutting attachments (such as the CA2460), as well as other "Victor Style" heavy-duty equipment that accepts the 1-101 seat configuration.

Application Notes

The 2-1-101 is strictly for use with Acetylene. Attempting to use this tip with Propane, Propylene, or Natural Gas will result in flame instability and potential equipment damage due to the lack of a recess for flame anchoring required by alternate fuels. For shops utilizing Acetylene, this Size 2 tip is a critical inventory item, bridging the gap between light sheet metal work and heavy plate processing. Its robust design withstands the rigors of daily industrial use, including heat reflection during hole piercing and beveling.
