Pressure Gauge for Welding Regulators

This Miller-Smith Equipment gauge measures 0 to 30 psi and 0 to 2 Bar for welding regulator applications. It features a 2-inch steel case in black with brass and bronze wetted parts. The bottom-mounted 1/4 inch MNPT connection suits panel installations where liquid filling is not required.

Accuracy Under Continuous Use

The gauge maintains a +/-3-2-3 percent accuracy rating across its dual-scale range during sustained pressure monitoring. Its basic steel case construction provides durability for ongoing welding operations without liquid damping. The 1 psi smallest graduation supports consistent readings throughout extended work periods.

Straightforward Bottom-Mount Installation

The 1/4 inch MNPT bottom connection allows direct threading into compatible regulator ports without panel mounting hardware. No calibration certificate is included, so verification may be needed for critical applications. The non-liquid-filled design eliminates leakage risk but offers less vibration dampening than filled alternatives.

Questions about this item

How much heat or noise does the GA134-03 produce when running all day?

The gauge is a passive mechanical instrument with no powered components, so it generates no heat and makes no noise during continuous use.

What existing fitting must I already have to install this gauge?

You need a female 1/4 in MNPT port on the regulator or manifold for the gauge's bottom-mounted male thread to screw directly into.

Will the 0-30 psi scale match the older regulator I plan to keep?

Yes, if your existing regulator operates within 0-30 psi (0-2 Bar), the gauge's primary and secondary ranges align exactly with that working pressure.
