A gas regulator is used to maintain and regulate the pressure of the gas as it is released. They work to reduce high-pressure gas in a cylinder to a lower, usable level as it passes from the cylinder to another piece of equipment, in this case, a welding machine.

Choosing a Gas Regulator

When picking a gas regulator, first things first is to make sure you’re getting a regulator designed for the gas you’re using. The construction of regulators varies depending on the gas that they’ve been designed for. A regulator made for one type of gas, like carbon dioxide (CO2), may not be safe or effective when used with a different gas (like pure argon).

Regulators that are designed for non-combustible gases come with a right-hand thread. Regulators designed for combustible gases come with a left-hand thread and are also marked with a notch on the nut.

This is true regardless of whether you get a top or side entry regulator. The orientation of your regulator will depend on the gas bottle you’ve got and whether it has a side or top entry.

Once you’ve selected your regulator and attached it to the gas bottle, make sure to loosen the valve before turning on the gas. That way, the diaphragm isn’t subjected to sudden pressure, and your regulator will last longer.  

We offer argon, oxygen, acetylene, and LPG regulators, as well as an argon flowmeter.
