639993 - Victor 639993 Replacement Mixer Throat #100

Precision Replacement for Oxy-Fuel Safety

The ESAB Victor 639993 Mixer Throat #100 is a critical internal component designed for specific Victor oxy-fuel mixer assemblies. In the world of industrial gas cutting and welding, the mixer is the heart of the torch, responsible for blending oxygen and fuel gas at precise ratios to create a stable, controllable flame. The throat of the mixer plays a pivotal role in this process, often utilizing the Venturi effect to accelerate gas flow and ensure thorough turbulence-free mixing.

Over time, the internal components of a torch mixer can suffer from heat stress, carbon buildup, or mechanical wear. A worn or damaged throat can disrupt the gas flow dynamics, leading to an unstable flame, difficulty in setting a neutral flame, or, more dangerously, an increased risk of flashback or backfire. Replacing the throat with this genuine OEM part restores the original engineering specifications of your equipment.
