OVERVIEW

Ultimate Reliability for Critical Welding

For professional welders and fabricators working with exotic materials or in environments requiring absolute gas purity, the Miller Smith 322-70-24-00-00 Stainless Steel Regulator is the tool of choice. When welding reactive metals like titanium or high-grade stainless steel, even trace amounts of atmospheric contamination or moisture can ruin a weld. This regulator's 316 stainless steel construction ensures that your shielding gas remains pure from the cylinder to the torch, preventing oxidation and defects caused by off-gassing components found in standard brass regulators.

The two-stage design is a game-changer for long welds and automated processes. It automatically compensates for the drop in cylinder pressure as you work, providing a steady, unwavering flow of gas until the tank is practically empty. This means you won't have to constantly adjust your settings or worry about flow surges that could disrupt your shielding coverage. With a delivery range of up to 100 PSI, it is versatile enough for standard TIG/MIG applications as well as high-pressure purging requirements.

Durability is built into every aspect of the 320 Silverline Series. The stainless steel diaphragm is convoluted for sensitivity but robust enough to handle the rigors of industrial use. The metal-to-metal seal ensures a tight closure that won't leak, saving you money on wasted gas and increasing safety in the shop. The regulator also features a captured vent port, adding an extra layer of safety by allowing potential leaks to be vented away from the workspace.

This model comes with a CGA 580 connection, making it compatible with standard Argon, Nitrogen, and Helium cylinders. The large 2-1/2 inch gauges are easy to read even from a distance, allowing you to monitor tank levels and output pressure at a glance. If your work demands the highest standards of cleanliness and consistency, upgrade to the Miller Smith 322-70-24-00-00 and experience the difference high-purity equipment makes in your weld quality.

FAQ

A two-stage regulator reduces the cylinder pressure in two steps, which allows it to maintain a constant delivery pressure regardless of fluctuations in the inlet pressure as the gas cylinder empties. This provides more stable flow control compared to single-stage regulators.

316 Stainless Steel is used for its superior corrosion resistance and high purity. It prevents contamination of the gas stream from the regulator material itself (off-gassing) and withstands corrosive environments or gases better than brass.

The CGA 580 connection is the standard standard for inert gases, including Argon, Nitrogen, and Helium. It is not compatible with oxidizers like Oxygen or flammables like Acetylene.

Yes, the manufacturer notes that a Cross Purge Assembly must be used with this series of regulators to ensure effective purging of hazardous gas traces during cylinder changes, especially in high-purity or hazardous applications.

The captured vent port (1/16" FNPT) in the bonnet allows users to connect tubing to pipe vented gases away to a safe location. This is a safety feature designed to handle potential diaphragm failures when using hazardous gases.

Yes, both the front and rear bonnets are threaded, allowing for front panel mounting configurations, which is common in laboratory and instrument bench setups.

This regulator is rated for a maximum inlet pressure of 3500 PSI, making it suitable for use with high-pressure cylinders.

Yes, the design is engineered to withstand internal vacuums, which is necessary during purging operations to remove atmospheric contaminants before introducing the process gas.
