0311-0129 - Victor 4-W-J Welding Nozzle Size 4

Technical Overview of the Victor 4-W-J Elbow Tip

The Victor 0311-0129 4-W-J Elbow Tip is a specialized welding component designed for precision and durability in oxy-acetylene applications. Part of the renowned Victor J-Series line, this nozzle is engineered to fit J-Series torch handles, providing a reliable solution for light-to-medium duty welding tasks. The assembly features a one-piece copper elbow tip which offers excellent thermal conductivity and resistance to heat deformation, ensuring a long service life even under continuous use.

A key technical feature of the 4-W-J tip is its individual Spiral Mixer. This built-in component is critical for optimizing flame characteristics, ensuring a thorough mix of oxygen and fuel gas (Acetylene or Hydrogen) before ignition. The result is a stable, long cone flame that provides consistent heat input, essential for high-quality welds. The mixer design also aids in preventing flashback, enhancing the safety profile of the equipment.

The connection mechanism utilizes a double O-ring seal, a hallmark of Victor's design philosophy. This feature allows for a gas-tight seal to be achieved by hand-tightening, eliminating the need for a wrench during tip changes and reducing wear on the torch head threads. The brass coupling nut includes a built-in snap ring that serves to protect the cone-end of the tip from damage when not in use or during handling. All Victor nozzle assemblies, including the 4-W-J, undergo 100% flame testing prior to distribution, verifying performance parameters and flow consistency.

This Size 4 tip is calibrated for specific material thicknesses, typically suitable for welding steel ranging from approximately 1/4 inch (6.4 mm) depending on the specific torch settings and operator technique. It represents a critical consumable for professionals requiring precise flame control and reliable equipment integration within the Victor gas apparatus ecosystem.
