Best Welding Gas flow Regulators for TIG and MIG Welder Reviews & Buyer’s Guide 2020

Feature image for Best Welding Gas flow Regulator article

Choosing the proper gas welding regulator is not only important for maintaining the proper flow of gases while you weld. It also improves safety and ensures the best welding results. You wouldn’t want a faulty regulator especially if you are dealing with combustible gases.

But which regulator is the best?

Although there are a few of them and each manufacturer ensures that theirs is the best, there are a few that are more reliable than others. Check out our picks that we have singled out after a detailed analysis of each and every one of them.

Just a quick shout out guys! Rest assured that I put these products on the list due to their quality and my personal opinion as let’s say, experienced welder (burn marks, ruined eyesight, and all).

I just want to be transparent with you and inform you that my site Weldingpros.net may obtain a share of sales or other monetary compensation from the links on this page.

So, buddy, I hope that using this article you pick a great welder and put some nice bits on that metal (and if not just grind it a little ;)).

Best Gas Welding Regulators

The primary usage of a gas welding regulator is to ensure the proper flow of the gas consumed by the welding machine. Their job is to mix the combination of gasses properly so each one is emitted in the correct proportion. The idea is keeping the inlet pressure and the outlet pressure as constant as possible.

Gar regulators come in different sizes, shapes, and forms. They differ in terms of performance, maximum inlet pressure, size constraints, purity requirements, types of gas being used, and sometimes personal preferences. So whether you are doing MIG welding or TIG welding, you will need to make certain adjustments.

Let’s see which are the best types of gas regulators that you can find today.

1. YesWelder Flow Meter Gas Regulator for Argon/CO2 Welding

YesWelder Flow Meter Gas Regulator for Argon CO2 Welding

 

The YesWelder Flow Meter gar regulator includes a high-density molecular brass filter set at the pressure reducer interface. It helps to prevent impurities get into the gas cylinder. This actually greatly improves the normal flow of the meter and extends its life.

This regulator is made out of copper and comes with a flow gauge and a precision regulator. A very accurate 1 1/2″ diameter pressure gauge is fitted (reading from 0 – 4000 PSI) and is more than easy to read. It actually has a very wide application as it comes with a CGA – 580 Tank that can fit 00% Argon, 75% Argon / 25%CO2, 80% Argon / 20%CO2 making it ideal both for MIG and TIG applications.

The design is actually a combination of a flow meter and a regulator created as a single unit.

2. BETOOLL HW9003 Argon/CO2 Mig Tig Flow Meter Gas Regulator

This is an Argon / CO2 regulator and flow meter coming from BETOOLL. It has a pressure meter measuring from 0 to 4000 psi. This one is actually more reliable and accurate as it does not have a standard flow-gauge-style regulator, instead, it uses a diaphragm. The output flow can be adjusted from 10 to 60 cubic feet per hour.

It comes with a CGA-580 fitting, meaning that it can be used with argon, nitrogen, and argon/CO2 mixed gas tanks. However, it does not fit CO2 gas cylinders. Also, a very nice thing about it is its female 9/16″ x 18 nut or the male 5/8″ x 18 fittings. This allows you to fit any Hobart, Lincoln, or Miller welding machines as long as they use a 5/8″ x 18 male nut.

BETOOLL HW9003 Argon/CO2 Mig Tig Flow Meter Gas Regulator Gauge Welding Weld
  • Brand New BETOOLL Argon / CO2 regulator and flow meter.
  • Flow Meters are more accurate than the flow gauge regulators.
  • The pressure gauge which shows how much gas is left in the tank goes from 0 to 4000 psi.
  • And this flowmeter does not use a diaphragm, so it is more reliable than the flow-gauge style regulators.

4. Taprite T742HP Primary Double Gauge CO2 Regulator, Brass

The Taprite T742HP can be used with any CO2 tank with a CGA-320 valve. The regulator comes with dual gauges, one to measure the PSI and the other to determine the CO2 left in the gas cylinder. You can use the knob on the front and adjust the output pressure. On the other hand, the high-pressure ports have female threads in order to prevent them from being used as low-pressure outlets. An internal relief valve is built-in so it opens whenever the pressure exceeds 15 PSI.

A permanent Quad-Ring Seal is also added to prevent leaks from happening and there is also a NADS 1600C shutoff for safety as well. Horse barbs use a 5/16 inch I.D. pressure tubing and all regulators are pressure tested with impeccable flow rates. The low-pressure gauge (the top one) is supposed to indicate output pressure to the keg and allows for pressure adjustment of  1 to 50psi. The high-pressure gauge (the one on the side) shows how much CO2 pressure is left in the tank.

Buying Guide of the Best Gas Welding Regulator

The best pieces of advice when determining which gas regulator to get is to find one that will regulate the gas pressure for the gas intended for your welding machine. But there are a whole lot of things that you have to take into account. So let’s consider them together.

What Gas is the Regulator Designed for?

Using the wrong one may have hazardous effects on the entire process.

So fir instance, if you use an acetylene regulator to regulate propane gas, the propane itself will damage the inside of the regulator or cause it to disintegrate.

It will lead to leakage and also result in a very dangerous situation.(1)

Bar Outlet on CO2/Argon regulator

Most gas regulators have a 0 to 10 bar outlet. But if you have to set it to 0.2 it makes things far more difficult. Thus 0-4 welding gas regulators are a far better option in this case as it is far easier to adjust the lowe delivery pressure needed.(2)

Gauges On A Gas Flow Regulator (CFH/PSI)

You also have to know the difference in gauges with different gases, as Argon uses CFH (cubic feet per hour) while oxygen is measure din PSI (pounds per square inch).

 

 

Male and Female Connectors

Male and Female Connectors for a gas flow regualtorThere are two types of connectors, male and female ones, and gas regulators usually have everything labeled for users to known which one to use.

This is necessary as you do need to properly connect the gas bottle when working in order to have favorable flow rates.

But if you don’t have the required connectors you can still use an adapter for the bottle connection.

Frequently Asked Questions [F.A.Q]

Are argon and CO2 regulators the same?

The majority of CO2 regulators are the same as Argon ones. But the main difference is the cylinder fitting. CO2 welding gas regulators have a female fitting while all the other ones have a male one. CO2 regulators have a male thread which means that the regulators then have to be female.

How long do gas regulators last?

Welding gas regulators should be replaced every 10 years. The best type of indicator is visual signs of deterioration. However, each regulator has an expiration date stamped on it which you should follow.

What is SCFH in welding?

The abbreviation SCFH stands for standard cubic feet per hour. This is a type of measurement needed to understand how much shielding gas you are applying.

Conclusion

Although it is often disregarded, gas regulators are an important part of your welding machine setup. Beginner welders may not know this when they start but more experienced ones will tell them that this is a very important part of the entire process. In order to be able to weld properly, the gas service needs to be properly adjusted based on the various parts that we talked about above. Always consider carefully your regulators and follow the instructions so you can attain quality work.
