0781-4253 - Victor GT350 Heavy Duty Two-Stage CO2 Regulator 5-60 PSI

Victor GT350-60-320: The Welder's Choice for CO2 Control

When it comes to shielding gas regulation, consistency is key to a quality weld. The Victor 0781-4253 GT350-60-320 Regulator is a heavy-duty, two-stage regulator designed specifically for Carbon Dioxide (CO2) service. In MIG welding and flux-cored applications where CO2 is used as a shielding gas, maintaining a steady flow and pressure is essential to prevent porosity and ensure arc stability. The GT350's two-stage architecture excels here by compensating for the drop in cylinder pressure as the tank empties, meaning you won't have to constantly adjust your settings while you work.

Industrial Grade Durability

Fabrication shops can be tough on equipment, which is why the GT350 series is built to last. The body and bonnet are machined from high-strength forged brass, offering superior resistance to impact and wear compared to lighter-duty alternatives. The internal components are equally robust, featuring a stainless steel diaphragm in the second stage for accurate pressure regulation and long-term reliability. This model connects via a CGA 320 fitting, ensuring compatibility with standard industrial CO2 cylinders, and supports inlet pressures up to 3000 PSIG.

Performance Specifications

This regulator provides a delivery pressure range of 5 to 60 PSIG, making it versatile for various shop needs beyond just welding, such as purging or pneumatic testing. The large 2.5-inch gauges are protected by a sturdy case and provide clear readings at a glance. The adjustment knob is designed for smooth operation, allowing welders to dial in the exact pressure required with ease. Safety is also paramount, with built-in pressure relief valves to protect the low-pressure side of the system.

Why Choose Two-Stage?

For professional welders, time is money. A single-stage regulator often requires the operator to increase the spring tension as the cylinder pressure falls to maintain the same output, a phenomenon known as "droop" or "climb" depending on design. The Victor GT350 eliminates this variable, providing a set-it-and-forget-it solution that lets you focus on laying the perfect bead. Invest in the Victor GT350-60-320 for a regulator that works as hard as you do.
