0387-0024 - Victor Size 4 W-Series Welding Nozzle with Spiral Mixer

Technical Overview of the Victor 4-W-CS Welding Nozzle

The Victor 0387-0024 4-W-CS Welding Nozzle is a precision-engineered component designed for the W Series product line, specifically compatible with 300 Series torch handles. This nozzle distinguishes itself through its integrated individual Spiral Mixer. Unlike generic tips that may rely on handle-based mixing, the spiral mixer within the nozzle assembly ensures optimized turbulence and gas blending, resulting in optimum flame characteristics for Acetylene and Hydrogen fuel gases. The assembly is rated as Size 4, suitable for a specific range of material thicknesses in general-purpose welding and preheating applications.

Structurally, the nozzle features a one-piece copper elbow tip, chosen for its high thermal conductivity and resistance to spatter adhesion. The connection interface is secured by a Brass Coupling Nut equipped with a built-in snap ring. This snap ring serves a critical protective function, shielding the cone-end from physical damage during storage or handling. A defining technical feature of this assembly is the double O-ring seal mechanism. This design creates a positive, gas-tight connection that eliminates the need for torque application via a wrench, thereby reducing the risk of thread deformation or overtightening damage to the torch head.

The geometry of the tip is set at a 65-degree angle, providing a balance between reach and visibility for the operator. The flame profile is characterized as a "long cone flame," which provides a focused heat source necessary for precise puddle manipulation in welding operations. Every unit undergoes 100% flame testing before leaving the manufacturing facility, ensuring that flow rates and flame geometry meet strict quality assurance standards. This nozzle represents a high-fidelity solution for industrial MRO environments requiring reliable oxy-fuel equipment.
