Victor 3-101 Size 2 Acetylene Cutting Tip | 1-1/2 Inch Capacity

Technical Precision: Victor 3-101 Size 2 Acetylene Tip

For welders and metalworkers demanding precision in their oxy-acetylene cutting, the Victor 0331-0015 (Series 3-101, Size 2) is the go-to tip for medium-duty applications. This tip is designed to deliver a clean, controlled cut on mild steel up to 1-1/2 inches thick. The one-piece copper design is not just about durability; it is about performance. Copper's high thermal conductivity keeps the tip cooler during extended cuts, preventing the preheat holes from clogging due to molten spatter adhesion and reducing the likelihood of flashback.

Optimized Gas Flow and Pressure Settings
To achieve the best results with this Size 2 tip, correct pressure settings are vital. The manufacturer specifies a cutting oxygen pressure range of 40-45 PSIG. This pressure is sufficient to blow through 1.5-inch plate without causing turbulence that would roughen the cut face. The preheat oxygen should be set between 4-12 PSIG, while the acetylene fuel gas requires a low-pressure setting of 3-7 PSIG. Adhering to these parameters ensures a neutral preheat flame that brings the steel to ignition temperature rapidly without melting the top edge excessively.

Compatibility and Maintenance
This tip is part of the 3-101 family, meaning it is compatible with Victor's medium-duty torch handles (like the 100 series) and cutting attachments (1300 and 1200 series). It is strictly for use with Acetylene gas; attempting to use it with alternate fuels like Propane or Propylene will result in poor performance and potential safety hazards due to the specific recess and porting design meant for Acetylene's flame velocity. The tip features a cutting speed capability of 13 to 17 inches per minute, allowing for efficient workflow. To maintain this performance, regular inspection of the seating surface and cleaning of the orifices with a proper tip cleaner is recommended to ensure the gas stream remains unobstructed and true.
