0324-0074 - Victor W-1 Series Size 4 Acetylene Welding Nozzle

Technical Overview of the Victor 4-W-1 Welding Nozzle

The Victor 4-W-1 Welding Nozzle (SKU: 0324-0074) is a precision-engineered component designed for medium-duty oxy-fuel applications. Part of the W-1 Series, this nozzle is specifically calibrated as a Size 4 tip, making it suitable for a defined range of material thicknesses in general-purpose welding and preheating scenarios. The assembly is constructed with a one-piece swaged copper elbow, which provides excellent thermal conductivity and resistance to deformation under high-heat conditions. The tip geometry features a 65-degree angle and a total length of 4-1/2 inches, dimensions that facilitate access to various joint configurations while maintaining a safe distance from the heat source.

A critical technical feature of the 4-W-1 nozzle is its integrated spiral mixer. Unlike universal mixers, this individual mixer is optimized for the specific flow rates of a Size 4 tip, blending oxygen and fuel gas (Acetylene or Hydrogen) to produce a stable, long cone flame. This ensures consistent heat output and reduces the likelihood of flashback. The connection mechanism utilizes a double O-ring seal, which creates a gas-tight interface with the torch handle. This design eliminates the need for wrench tightening, preserving the integrity of the threads and sealing surfaces over time. The nozzle is compatible exclusively with Victor 100 Series torch handles.

Durability is further enhanced by the brass coupling nut, which includes a built-in snap ring. This ring serves to protect the cone end of the nozzle from physical damage during handling and storage. Every unit undergoes 100% flame testing at the manufacturing facility to verify flow characteristics and seal integrity before shipment. The nozzle is engineered to support the withdrawal rates associated with standard acetylene cylinders, provided the 1/7th rule is observed, or a manifold system is employed for higher volume requirements.
