0781-2701 - Victor GRF400-580 Argon/CO2 Flowmeter Regulator

Precision Shielding Gas Flow for MIG & TIG Welding

Upgrade your welding setup with the Victor® GRF400-580 Regulator/Flowmeter, a high-quality gas control device engineered for the welder who demands accuracy and reliability. Model 0781-2701 is part of the renowned Victor GRF400 series, designed specifically to provide smooth, consistent shielding gas flow for light fabrication, automotive restoration, and serious hobbyist applications. Unlike simple gauge regulators, this flowmeter uses a vertical tube and float ball system, giving you a visual and accurate reading of your gas flow in Standard Cubic Feet per Hour (SCFH).

The GRF400-580 is built to last. It features a robust brass body and an impact-resistant Lexan flowtube that can survive the rigors of a garage or small shop. The flowtube is housed within a one-piece protective cover, shielding it from sparks, spatter, and impact. The integrated precision needle valve puts you in complete control, allowing you to dial in the exact flow rate needed for your specific weld joint and position. This precision helps eliminate porosity caused by insufficient coverage and saves money by preventing the over-consumption of expensive shielding gases.

This unit is versatile enough to handle the three most common shielding gases. It is calibrated for Argon (5-50 SCFH), Helium (20-150 SCFH), and Carbon Dioxide (5-40 SCFH). The inlet is a standard CGA-580, compatible with Argon, Nitrogen, and Argon/CO2 mix cylinders. The outlet is a standard CGA-032 (5/8"-18 RH Female), ready to accept standard gas hoses found on most Miller, Lincoln, and ESAB machines. Whether you are TIG welding stainless steel or MIG welding mild steel, the Victor GRF400-580 ensures your gas delivery is one variable you won't have to worry about.
