0781-2703 - Victor GRF400-320 CO2 Flowmeter Regulator, CGA 320, 2-40 SCFH

Reliable CO2 Flow Control for Light Duty Welding

If you are looking for an economical yet high-quality solution for managing your CO2 shielding gas, the Victor GRF400-320 Regulator/Flowmeter is an excellent choice. Designed by Victor, a leader in gas equipment, this unit is perfect for hobbyists, maintenance crews, and light fabrication shops that need reliable performance without the bulk and cost of heavy-duty industrial regulators.

Compact and Efficient Design
Space is often at a premium in mobile welding carts and small workshops. The GRF400-320 combines the regulator and flowmeter into one compact unit. This "all-in-one" design not only saves space but also makes setup a breeze. You simply attach it to your CO2 tank using the CGA 320 fitting (don't forget your washer!), connect your gas hose, and you are ready to weld. The easy-to-read flow tube lets you dial in your gas flow between 2 and 40 SCFH with precision, ensuring you get the perfect shield for your weld puddle without wasting gas.

Designed for CO2 Applications
Carbon Dioxide is a popular shielding gas for MIG welding because it provides deep penetration and is cost-effective. However, CO2 can be tricky to regulate because it can freeze up regulators during heavy use. The GRF400-320 is specifically engineered to handle CO2 for light-duty cycles (rated at 20%). This means it performs reliably for standard tacking, short beads, and general repairs. If you are running long, continuous production welds, you might need a heated regulator, but for most general repair and light fabrication tasks, this unit is the perfect fit.

Key Benefits:

• Economical: Get Victor quality at a price point that fits smaller budgets.
• Easy to Read: The clear flow tube and ball float take the guesswork out of setting your gas flow.
• Standard Fit: Works with standard CO2 cylinders and gas hoses found in almost every welding shop.

Upgrade your welding setup with the Victor GRF400-320 and experience consistent gas flow that leads to better weld quality and less spatter.
