3-101-0 - Uniweld 3-101 Series Acetylene Cutting Tip, Size 0, Victor Style

Technical Overview of the Uniweld 3-101-0 Cutting Tip

The Uniweld 3-101-0 is a precision-manufactured cutting tip designed for oxy-acetylene cutting processes. Engineered as a direct replacement for Victor 3-101 series tips, this component is fully compatible with Victor 100 Series cutting attachments and torch handles, as well as compatible aftermarket medium-duty equipment. The tip features a Size 0 orifice configuration, calibrated to effectively cut mild steel ranging from 3/8 inch (9.5 mm) to 1/2 inch (12.7 mm) in thickness.

Constructed from high-grade copper, the 3-101-0 utilizes a one-piece design that ensures optimal thermal conductivity and durability under high-heat conditions. The internal geometry is machined to strict tolerances to maintain a stable preheat flame and a focused cutting oxygen stream. This specific series is strictly for use with Acetylene gas; the port design and seating surfaces are not compatible with alternate fuel gases like Propane or Propylene, which require two-piece recessed tips (such as the 3-GPN series).

Operators will appreciate the consistent seating provided by the precision-tapered base, which ensures a leak-proof seal within the torch head. The tip is suitable for both manual hand cutting and machine cutting applications where a medium-duty Victor-style torch is employed. Proper gas pressure settings are critical for optimal performance; for a Size 0 tip, typical parameters involve an oxygen pressure of approximately 30-35 PSIG and an acetylene pressure of 3-5 PSIG, though operators should always consult the specific chart for their torch setup.

In industrial MRO environments, the Uniweld 3-101-0 serves as a reliable consumable for fabrication shops, structural steel repair, and general maintenance tasks requiring precise thermal cutting of carbon steel plate and pipe.
