Buying Guide of the Best gas welding regulator

Before you buy a welding gas regulator make sure that you get one that will work properly with the gas that you use and with the machine that you use.

What gas is the regulator designed for?

You want to make sure that the regulator is made from materials that are compatible with the gas you use the most. If you use a regulator designed for acetylene to regulate propane gas the propane would cause the internal components of the regulator to disintegrate. This would cause leakage and possible hazards.

The bar outlet

You need to consider getting a regulator that has a low bar input so it is easier for you to make the right adjustments. If you have a 0 to 10 bar outlet on your regulator but you have to set it at 0.2 bar this can be very difficult to do.


You need to look at the gauges on the regulator and see how they read. Argon is typically measured in CFH but oxygen is measured in PSI. It is important that the gauge be able to tell you the proper reading for the gas you are using.


The connectors may be female and they may be male. You want to know what type of connector the regulator has so you can determine if you have to have an adapter to connect it to your gas bottle.

Frequently Asked Questions

Q. Are argon and C02 regulators the same?

The argon regulator and the oxygen regulator are basically the same. The delivery gauge is the main thing that differs on these items. When you are looking at the delivery gauge on an oxygen regulator normally show PSI pressure readings and argon delivery gauges read in CFH. The cylinder fitting on an oxygen regulator is female and on the argon the fitting the threads will most likely be male.

Q. How do you use a welding gas regulator?

The welding gas regulator connects to the gas bottle and there are gas lines that then connect to your welding machine. You adjust the gas flow to the proper setting and then you start welding.

The regulator connects the flow of gas to the tip you are using to weld with. Then it combines the needed gases in the perfect combinations so you get the proper flame.

Q. What is the correct gas pressure for MIG welding?

The flow of gas for MIG welding is measured in cubic feet of gas per hour. (CFH) The flow rates required to perform MIG welding is very low in comparison to the flow rates required to oxygen rates needed for welding or plasma cutting.

For a 3/8” nozzle the minimum suggested flow is 15 CFH and the Maximum flow is 30 CFH, with the average setting being between 18 and 22 CFH. For ½” nozzles, the min flow is 18 CFH and the maximum is 40 CFH.

Final Note

If you want a high-quality regulator that will give you precise and accurate readings consider the BETOOLL HW9003. This device is constructed without an internal diaphragm so it gives you the most accurate readings and it lasts longer because there is no diaphragm to eventually need replacing.

If you are looking for a flow meter and want to spend less than seventy-five dollars consider the SPARC Dual Output Flowmeter. This unit is reasonably priced and provides you with all of the accuracy and reliability that you want from one of these devices.
