Single-Stage Flowmeter Regulator
The Miller-Smith Equipment H2051B-580 is a single-stage flowmeter regulator built for welding applications. It connects to a gas cylinder via a CGA-580 inlet and delivers a regulated pressure of 50 psi for argon, carbon dioxide or helium supply.
Precision Flow-Adjustment Valve
The included precision flow-adjustment valve allows the operator to set the exact gas flow required for the weld. This accessory changes the setup from simple pressure regulation to accurate flow control, which is critical for consistent shielding gas coverage.
Brass Body with Stainless Steel Components
The regulator body is constructed from brass with a 2.0 in diameter and incorporates 300 Series Stainless Steel elements. The 1 1/2 in supply pressure gauge reads 0 to 4000 psi while the maximum inlet pressure is rated at 3 000 psi. The 5/8 In. -18 RH Internal outlet connection fits standard welding hose fittings for direct torch attachment.

Questions about this item
Will the 1 1/2 in supply pressure gauge need periodic recalibration?
The gauge reads 0 to 4000 psi and is built into the brass body; no user recalibration procedure is described, so plan on professional service if readings drift.
What limits continuous flow when the cylinder pressure drops?
The single-stage design delivers a fixed 50 psi outlet; as inlet pressure falls below that level the regulator can no longer maintain the set flow.
How hot does the brass body get during an all-day welding shift?
The 2.0 in brass body dissipates heat from the expanding gas; under normal argon or CO₂ use it stays warm but not hot enough to require extra cooling.
