Single-Stage Flowmeter Regulator

The Miller Enterprises 22-80-320 is a single-stage flowmeter regulator built for general-purpose welding. Its brass body and neoprene diaphragm handle argon, carbon dioxide and helium from a high-pressure cylinder. A CGA-580 inlet connects to the supply while a 5/8 in.-18 RH internal outlet feeds the hose. A filtered seat and flowball are included.

Welders Using Argon, CO2 or Helium

This regulator suits welders who need a 0 to 80 psi delivery range from a cylinder rated up to 3,500 psi. The UL-listed design includes a 2 in. supply gauge reading to 4000 psi. Buyers who require multi-stage pressure control or a different outlet thread should look at other models.

0 to 80 psi Delivery Range

The adjustable delivery pressure spans 0 to 80 psi, which is the key figure for matching the regulator to your welding process. The single-stage construction reduces inlet pressure directly to this working range. Confirm that your application operates within these limits before fitting the unit.

Questions about this item

Should I pick the 0-80 psi delivery range or a different regulator for argon welding?

The 0-80 psi delivery range on this Miller 22-80-320 suits argon, CO₂ and helium shielding gases; choose it when your process needs flow control up to 80 psi.

What does the 4000 psi supply-pressure gauge tell me during a weld?

The 4000 psi gauge shows remaining cylinder pressure so you know when to change tanks; it reads up to the 3,500 psi max inlet rating of the brass body.

How does the CGA-580 inlet and 5/8-18 RH outlet affect hose compatibility?

CGA-580 connects directly to standard argon/CO₂/helium cylinders; the 5/8-18 RH internal outlet accepts common welding hoses and flowmeter fittings.
