639885 - Victor Style Mixer for W300/W400 Torch Handles

Precision Gas Mixing for Heavy-Duty Applications

The #1A-2A Mixer W300/400 is a critical component designed to facilitate the precise blending of oxygen and fuel gases within heavy-duty welding and heating torch assemblies. Engineered to meet the rigorous standards of industrial fabrication, this mixer is fully compatible with Victor W-300 and W-400 series handles, ensuring seamless integration into existing oxy-fuel setups. The unit functions by creating a controlled turbulence zone where gases are mixed thoroughly before entering the welding or heating tip, a process essential for maintaining a neutral, oxidizing, or carburizing flame as required by the operator.

Constructed from high-grade brass, the mixer offers superior thermal conductivity and resistance to deformation under high-heat conditions. The internal geometry is machined to tight tolerances to prevent flow restrictions and back-pressure, which significantly reduces the risk of flashback during operation. The assembly features dual O-ring seals that provide a secure, leak-proof connection to the torch handle, maintaining system integrity and operator safety. This component is suitable for use with various fuel gases, including acetylene, propane, and propylene, depending on the tip configuration used downstream.

For maintenance and repair operations (MRO), the #1A-2A Mixer represents a reliable replacement part that restores the functional efficiency of aging torch handles. By ensuring proper gas ratios, it enhances the quality of welds and the speed of heating applications, making it an indispensable asset for professional welders and fabricators demanding consistency and precision.
