0781-9431 - Victor G350 Heavy Duty Acetylene Regulator CGA 300

Precision and Visibility for Professional Fabricators

For the professional welder, the regulator is the heart of the oxy-fuel system, and the Victor G350-15-300 Acetylene Regulator is designed to keep that heart beating steadily. Whether you are performing intricate heating applications or heavy-duty cutting, consistent gas flow is critical for maintaining a neutral flame and achieving high-quality results. This single-stage regulator delivers that consistency, smoothing out cylinder pressure fluctuations to provide a stable output that you can trust.

One of the first things you will notice about the G350-15-300 is the gauge quality. Victor has equipped this model with large, 2.5-inch high-contrast gauges. In the dim lighting of a welding booth or the glare of an outdoor job site, these gauges are significantly easier to read than standard 2-inch models. The clear markings allow you to track your remaining cylinder contents and your delivery pressure with precision, ensuring you never run dry in the middle of a critical cut. The polished brass housing of the gauges adds a layer of rugged protection against sparks and knocks.

Ergonomics play a huge role in daily comfort, and the G350 excels here as well. The adjustment knob is designed to be smooth and responsive, allowing you to dial in the exact pressure you need within the safe 2-15 PSIG range for acetylene. The internal mechanism features a stainless steel diaphragm and a high-strength alloy bonnet, ensuring that the regulator responds quickly to changes in demand—such as when you trigger a cutting torch. The CGA 300 connection fits standard commercial acetylene tanks (always check your tank valve type), and the 9/16"-18 outlet mates perfectly with standard
