Miller-Smith Flow Gauge Regulator CGA-580

The Miller-Smith Equipment Flow Gauge Regulator is a single-stage unit built for argon shielding gas. It connects to a cylinder through a CGA-580 inlet and delivers a fixed 50 cfh flow rate. The brass body uses high-conductivity wrought copper components and a neoprene diaphragm. A 2-inch gauge displays supply pressure up to 4,000 psi with a 3,500 psi maximum inlet rating.

Suits MIG and TIG setups needing fixed argon flow

Welders who require adjustable delivery pressure or a different gas service should look at another regulator. The single-stage design and 50 cfh limit mean it cannot serve applications that need variable flow or higher volume. Buyers using inlet connections other than CGA-580 will need a different model.

CGA-580 inlet with 50 cfh argon delivery

The decisive specification is the CGA-580 inlet paired with a 50 cfh delivery range for argon. This combination determines whether the regulator matches the cylinder and flow requirements of the specific welding process. Verify the cylinder fitting and required flow before purchase.

Questions about this item

What cylinder fitting does the CGA-580 inlet require on my gas supply?

The regulator connects directly to a cylinder valve with a CGA-580 outlet, which is the standard fitting for argon cylinders in many regions.

Will the 5/8 In.-18 RH internal outlet thread onto my existing MIG gun hose?

Yes, the 5/8 In.-18 RH internal outlet matches the common torch-end fitting used on many MIG and TIG welding guns.

How can I verify the 50 cfh flow setting once the regulator is installed?

Open the cylinder valve, adjust the knob until the 2 in gauge needle rests at 50 cfh, and confirm the supply gauge shows up to 4,000 psi cylinder pressure.
