Flowmeter Regulator for Argon, CO₂, Helium
This single-stage regulator connects to a cylinder via a CGA-580 inlet and delivers gas at a 50 psi outlet pressure. It includes a 6 ft hose with inert connections and a precision flow-adjustment valve for welding use. The brass body measures 2.0 in diameter and carries a 1 1/2 in gauge showing supply pressure up to 4000 psi. Maximum inlet pressure is 3000 psi.
Suits MIG and TIG welders using inert shielding
Designed for Argon, Carbon Dioxide and Helium service on standard cylinders. The single-stage design and fixed 50 psi delivery range will not meet the needs of jobs requiring multi-stage pressure stability or higher outlet pressures. Buyers needing a different inlet fitting or a wider pressure range should look at other models.
CGA-580 inlet with 50 psi delivery pressure
The regulator is built for cylinders fitted with a CGA-580 valve and provides a fixed outlet pressure of 50 psi through a 5/8 in.-18 RH internal outlet. This combination determines whether the unit matches your cylinder and welding process.

Questions about this item
What cylinder valve type must the gas supply already have for the CGA-580 inlet to connect?
The regulator fits a standard CGA-580 cylinder valve used for argon, carbon dioxide and helium.
Can the 5/8 in.-18 RH internal outlet thread mate with the fittings on my existing 6 ft inert hose?
Yes, the included 6 ft hose already has inert hose connections that match the 5/8 in.-18 RH outlet.
What reading on the 1 1/2 in. supply-pressure gauge confirms the regulator is delivering the set 50 psi?
The delivery gauge should hold steady at 50 psi while the flow-adjustment valve is open and gas is flowing.
