OVERVIEW

Victor 0305-0175 UM-350 Mixer Assembly

The Victor 0305-0175, also known as the UM-350 Mixer, is a critical component designed for heavy-duty oxy-fuel heating applications. Engineered by Victor Technologies, a leader in gas equipment, this mixer is specifically built to blend oxygen and fuel gases (such as acetylene, propane, or natural gas) safely and efficiently before they reach the heating nozzle. It serves as the interface between the torch handle and the heating tip, ensuring the correct volumetric ratios are maintained for optimal flame temperature and stability.

Constructed from high-quality brass, the UM-350 offers superior resistance to heat and corrosion, making it suitable for harsh industrial environments. It is designed to fit Victor "VanGuard" 300 series torch handles, including the popular 315FC and HD 310C models. This mixer is required when utilizing specific high-capacity heating nozzles, such as the Type MFA (for acetylene) and Type MFN (for alternate fuels like propane and natural gas). By using the correct mixer, operators ensure that the gas velocity and turbulence are managed correctly, which is essential for preventing flashbacks and sustaining a consistent heating flame.

In industrial maintenance and fabrication, the integrity of the mixing chamber is paramount. The UM-350 utilizes precision-drilled ports to create a uniform gas mixture, which translates to better heat transfer and fuel efficiency. Whether used for preheating thick steel plates, straightening structural members, or bending pipe, this mixer provides the reliability professionals demand. It is a direct replacement part, ensuring full compatibility with existing Victor heavy-duty apparatus.

FAQ

The UM-350 mixer is designed for Victor 300 Series heavy-duty torch handles, such as the 315FC and HD 310C.

This mixer is typically used with Type MFA (acetylene) and Type MFN (propane/natural gas) heating nozzles.

No, the UM-350 is a heating mixer. Cutting attachments usually have their own integrated mixing chambers or require a different configuration.

Yes, the mixer itself can handle both gases, but you must use the correct nozzle (MFA for acetylene, MFN for propane) attached to the mixer.

It is constructed from solid brass for durability and heat resistance.

Simply thread the mixer onto the torch handle output, and then thread your heating nozzle into the mixer. Ensure all connections are wrench-tight.

Yes, the mixer assembly typically comes with the necessary O-rings installed for a gas-tight seal.
