Pressure regulators for forming Gases

Regulators for forming gases. A mix of nitrogen and hydrogen protects the root of the weld from the inside, so it doesn't turn black from oxidation. It's used with stainless steel and thin-walled pipes, where you can't purge the weld from the outside. You can set the flow rate precisely, so you don't waste gas.
