Victor GT350-150-580 Two-Stage Inert Gas Regulator

Reliable Pressure for Professional Welders

When you are in the middle of a critical weld or a complex pressure test, the last thing you want to worry about is your gas flow fluctuating. The Victor GT350-150-580 Two-Stage Regulator is the heavy-duty workhorse designed to solve that exact problem. Unlike standard single-stage regulators that let pressure creep up as your tank gets low, this two-stage marvel keeps your output rock-steady from the moment you crack the valve until the tank is empty. It is the ideal upgrade for professionals using Argon, Nitrogen, or Helium who demand consistency in their workflow.

Built for the Shop Floor

Victor knows that welding shops and job sites aren't gentle places. That is why the GT350 series is constructed with a rugged forged brass body that can take a beating. The 2-inch steel gauges are clear and durable, allowing you to check your cylinder and delivery pressure at a glance without squinting through scratched plastic lenses. The adjustment knob is smooth and responsive, thanks to the Delrin cap bushing, giving you fine-tuned control over your gas flow. Whether you are TIG welding aluminum with Argon or pressure-testing an AC line with Nitrogen, this regulator gives you the confidence that your equipment is performing safely and accurately.

Versatility with CGA 580

The CGA 580 connection on this regulator makes it incredibly versatile for a welder's arsenal. It fits standard tanks for Argon (for MIG/TIG welding), Nitrogen (for purging and HVAC testing), and Helium. With a delivery pressure range of up to 150 PSIG, it offers plenty of power for most shop air tools or high-flow shielding gas setups, while still being sensitive enough for lower pressure needs. Stop fighting with cheap regulators that drift and leak; upgrade to the Victor GT350-150-580 and experience the difference that professional-grade gas equipment makes in your daily operations.

Why Choose Two-Stage?

For welders, consistency is key to a quality bead. A two-stage regulator acts like a cruise control for your gas flow. It automatically compensates for the dropping pressure in your gas cylinder, meaning you don't have to stop welding to tweak the knob every hour. This saves you time, reduces gas waste, and helps prevent porosity caused by inadequate shielding gas coverage near the end of a tank. It is an investment in quality that pays for itself in saved time and frustration.
