0305-0331 - Victor UM-350 Universal Torch Mixer for 315FC Handles

Upgrade Your Torch for Welding and Heating

If you are running a Victor rig, you know that versatility is key. The Victor 0305-0331 (UM-350) Mixer is the part you need to turn your cutting torch handle into a multi-purpose tool. Designed specifically for the Victor 315FC and other 300-series handles, this mixer allows you to attach welding elbows and heating nozzles, giving you the freedom to tackle brazing, soldering, and heavy heating jobs with the same handle you use for cutting.

We know that equipment in the shop takes a beating. That’s why the UM-350 is machined from solid brass. It handles the heat, resists the knocks, and threads on smooth every time. When you are switching from a cutting attachment to a rosebud for heating up a seized bolt or bending steel, this mixer drops right in. It creates the perfect blend of oxygen and acetylene (or other fuel gases) to give you a clean, hot flame that doesn't sputter or pop. A consistent flame means better puddles when you're welding and faster heat transfer when you're preheating.

Don't get stuck with a one-trick pony. By keeping a UM-350 mixer in your toolbox, you ensure your rig is ready for anything. It fits standard W-Series welding tips and MFA heating nozzles, making it a universal solution for your heavy-duty handle. The O-rings are tough, the threads are precise, and the performance is exactly what you expect from Victor. Stop struggling with poor flame quality or mismatched parts—grab the genuine Victor mixer and get back to work with a torch that performs as hard as you do.

Installation is simple: unscrew your cutting attachment, screw on the UM-350 mixer, attach your selected tip, and you are ready to light up. It’s a small investment that massively expands the capabilities of your oxy-fuel setup.
