0387-0145 - Victor Size 0 Acetylene Cutting Tip 3-101 Series

Technical Overview of the Victor 0387-0145 0-3-101-CS Cutting Tip

The Victor 0387-0145, also known as the 0-3-101-CS, is a premium-grade cutting tip designed for manual oxy-acetylene cutting operations. As part of the renowned Victor 3-101 series, this consumable is engineered to meet the rigorous demands of industrial metal fabrication, structural steel work, and general maintenance applications. The "Size 0" designation indicates its specific calibration for cutting mild steel ranging from 3/8 inch (9.5 mm) to 1/2 inch (12.7 mm) in thickness, making it one of the most versatile sizes for everyday fabrication tasks.

Manufactured from high-quality copper alloy, the 0-3-101 tip features a one-piece design that integrates the preheat and cutting oxygen paths into a solid, durable unit. This construction method ensures optimal heat conduction, preventing the tip from overheating during prolonged use, which is a common failure point in inferior multi-piece designs. The tip is precision-drilled to ensure a stable, concentric preheat flame that evenly brings the base metal to kindling temperature, while the central cutting oxygen bore delivers a high-velocity stream to remove molten slag efficiently.

This specific model comes in "CS" or clamshell packaging, providing retail-ready protection against dust and impact. It is designed to fit standard Victor 300 Series torch handles and cutting attachments, as well as compatible "Victor Style" equipment. Users should ensure their regulator settings are adjusted to the manufacturer's recommended pressures—typically around 30-35 PSI for oxygen and 3-5 PSI for acetylene for this specific tip size—to achieve the cleanest cut face and minimize slag adhesion. The 3-101 series is strictly for use with Acetylene gas; attempting to use alternative fuels like Propane or Natural Gas with this tip will result in poor performance and potential safety hazards due to the different burning velocities and recessed tip requirements of alternate fuels.

For MRO specialists and procurement officers, the Victor 0387-0145 represents a standard stock item that ensures continuity of operations for welding and cutting crews. Its reliability reduces downtime associated with tip fouling or premature burnout, providing a lower total cost of ownership compared to generic alternatives.
