Miller-Smith CGA-510 Regulator

The Miller-Smith CGA-510 is a single-stage brass regulator built for acetylene cylinders. It delivers a fixed 15 psi outlet pressure through a 9/16 in.-18 LH B connection. The 2 1/2 in. gauges show supply pressure up to 400 psi and the body measures 3.25 in. diameter. An external relief valve and nickel-plated bonnet are included. This UL-listed unit suits general-purpose welding and cutting tasks.

Check cylinder and hose compatibility

Verify the cylinder valve matches the CGA-510 inlet before ordering. Confirm the downstream hose or torch accepts a 9/16 in.-18 LH B fitting. Ensure the acetylene supply pressure does not exceed the 400 psi maximum inlet rating. The regulator is preset at 15 psi delivery; it is not adjustable for higher-pressure applications.

Replaces worn or missing single-stage acetylene

This unit replaces a damaged or lost CGA-510 regulator on existing acetylene setups. The upgrade is worth it when the old gauge reads inaccurately, the relief valve has activated, or the bonnet threads are stripped. It does not serve applications needing adjustable delivery pressure or multi-stage pressure control.

Questions about this item

Does the Miller Electric 40-15-510 regulator come with a hose or torch, or must they be purchased separately?

The regulator is supplied alone; the 9/16 in.-18 LH outlet and CGA-510 inlet require compatible hose and torch assemblies that are sold separately.

Should I choose the 15 psi delivery model or is a higher-pressure version available for heavier cutting?

This unit provides a 15 psi delivery range; other pressure ratings exist in the same series, so select the model that matches your torch manufacturer’s specification.

What does the 15 psi delivery pressure actually mean when the regulator is on a 400 psi acetylene cylinder?

The single-stage design reduces cylinder pressure up to 400 psi down to a steady 15 psi at the outlet, suitable for light welding and brazing tips.
