0305-0201 - Victor UM-1 Welding Mixer for J-Series Handles

Precision Gas Mixing for Light Duty Fabrication

The Victor 0305-0201 UM-1 Mixer is an essential component for professionals utilizing Victor's J-Series torch handles for light-duty welding, brazing, and soldering applications. Engineered to the high standards synonymous with the Victor brand, this mixer assembly is designed to blend oxygen and fuel gas—typically acetylene or hydrogen—into a homogenous mixture before it reaches the welding nozzle. This precise mixing is critical for maintaining a stable, neutral flame that allows for controlled heat input and clean metallurgical bonds.

Constructed from high-quality brass, the UM-1 mixer is built to withstand the thermal stresses of daily use while resisting corrosion and wear. It features precision-machined seating surfaces that ensure a gas-tight seal when attached to compatible handles such as the J-28, J-40, and the popular J-100C. The internal spiral design of the mixer promotes optimal turbulence, ensuring that the gases are thoroughly combined. This results in a flame that is easier to adjust and maintain, reducing the likelihood of popping or flashback during operation.

This mixer is specifically calibrated for use with Type 13 welding nozzles, generally in sizes 0, 1, and 2. It serves as the bridge between the handle and the tip, making it a vital part of any HVAC technician's or jeweler's toolkit. Whether you are repairing copper tubing, fabricating small metal parts, or performing delicate maintenance work, the Victor UM-1 Mixer provides the reliability and performance required for high-quality craftsmanship.
