22K44 - Victor UN-J Mixer Assembly for J-Series Handles

Precision Gas Mixing for Professional Fabrication

The Victor 22K44 Mixer Assembly (commonly referred to as the UN-J Mixer) is a fundamental component for light-to-medium duty oxy-fuel welding and brazing applications. Engineered by ESAB under the Victor brand, this mixer is designed to sit between the torch handle and the welding nozzle, performing the critical function of blending oxygen and fuel gas into a combustible mixture. The 22K44 utilizes a spiral mixing chamber, a design hallmark of Victor equipment, which creates turbulence to ensure a homogenous gas mix. This results in a stable, controllable flame that is essential for high-quality brazing, soldering, and welding operations.

Constructed from high-grade brass, the 22K44 is built to withstand the thermal cycling and mechanical stress typical of industrial environments. It features a double O-ring sealing system that fits securely into compatible torch handles, preventing dangerous gas leaks and minimizing the risk of flashbacks. This mixer is specifically calibrated for use with J-Series handles, including the J-28, J-40, and the widely used J-100C. It serves as the mounting point for various nozzle series, including Type 4, Type 13, and Type 108, making it a versatile addition to any fabricator's toolkit.

Proper maintenance of the mixer is vital for safety. The 22K44 is designed for easy inspection and cleaning. Its threaded connections are machined to tight tolerances, ensuring a secure fit that resists loosening during operation. Whether utilizing acetylene, propane, or other fuel gases, this mixer adapts to the specific flow requirements of the attached tip, providing consistent performance across different fuel types.
