0311-0474 - Victor 1-TE Replacement Tip End for Acetylene Welding & Brazing

Technical Overview of the Victor 0311-0474 1-TE Tip

The Victor 0311-0474 is a specialized replacement tip end designated as the 1-TE model, engineered specifically for oxy-acetylene welding and brazing applications. As part of the TE series division, this component is designed to interface seamlessly with compatible Victor nozzle assemblies, utilizing a standard 5/16" - 27 thread pitch. This specific threading ensures a gas-tight seal and proper alignment within the torch assembly, which is critical for maintaining safety and flame stability during operation. The tip features a Size 1 orifice, calibrated to deliver a precise volume of acetylene gas, making it suitable for light-to-medium gauge metal fabrication and repair.

Constructed from high-grade copper alloy, the 1-TE tip end is optimized for thermal conductivity, effectively dissipating heat away from the orifice to prevent pre-ignition or backfire. The overall length of the component is 1-1/2 inches, a dimension that balances reach with rigidity. In industrial MRO contexts, the ability to replace the tip end independently of the mixer or elbow reduces long-term operational costs. The internal geometry of the tip is machined to promote laminar gas flow, reducing turbulence before the ignition point. This results in a defined inner cone and a consistent outer envelope, essential for high-quality metallurgical bonding.

Technicians should note that this tip is rated exclusively for Acetylene gas. Attempting to use this specific tip geometry with alternate fuel gases such as Propane or Propylene may result in flame instability due to the differing burning velocities and BTU outputs of those gases. The 0311-0474 adheres to Victor's rigorous quality control standards, ensuring that the orifice diameter remains within tight tolerances to guarantee predictable heat output. This precision allows operators to calculate heat input accurately based on the material thickness, ensuring compliance with welding procedure specifications (WPS) that require specific tip sizes.

Installation requires a standard wrench fitment, and care should be taken not to over-torque the 5/16" - 27 threads, which could deform the seating surface. Regular inspection of the tip face for spatter accumulation or carbon buildup is recommended to maintain optimal flow characteristics. The 1-TE represents a critical consumable in the Victor oxy-fuel ecosystem, providing a reliable solution for precision thermal joining processes.
