223-0309 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 580, 150 PSI

Uncompromising Stability for High-Purity Applications

For professional welders and fabricators working with specialized applications requiring absolute precision, the Miller Smith 223-03-09 Silverline Regulator offers a level of performance that standard industrial regulators cannot match. While designed for analytical labs, this high-purity two-stage regulator is the ultimate upgrade for TIG welding stations or purging setups where gas consistency is non-negotiable. If you are working with sensitive materials like titanium or high-grade stainless steel, the purity of your shielding gas is just as important as your arc stability.

The defining feature of this regulator is its two-stage architecture. In standard welding operations, as your gas cylinder drains, the outlet pressure can fluctuate, leading to inconsistent gas coverage and potential weld defects. The 223-03-09 solves this by stepping down the pressure in two stages, ensuring that your flow rate remains rock-steady at your set point (up to 150 PSI) regardless of whether your tank is full or running low. This "set it and forget it" reliability allows you to focus entirely on the puddle without worrying about your gas delivery.

Durability meets precision with the Silverline series. The regulator is built from solid brass bar stock, ensuring it can handle the physical demands of a shop environment, while the plated finish protects the exterior from corrosion and grime. The internal stainless steel diaphragm provides a distinct advantage over rubber diaphragms found in standard regulators; it does not absorb atmospheric contaminants or moisture, ensuring that the Argon, Helium, or Nitrogen reaching your workpiece is as dry and pure as it was in the tank.

Equipped with a CGA 580 connection, this regulator fits standard inert gas cylinders. The large, easy-to-read 2-1/2 inch gauges allow you to monitor your tank levels and output pressure at a glance from across the room. Whether you are setting up a back-purge for sanitary stainless piping or running a high-end laboratory test bench, the Miller Smith 223-03-09 delivers the consistent, clean performance required for top-tier results.
