Welding Gas Cylinders: A Beginner's Guide

A quick run through of the basics a welding beginner needs to know about buying shielding gas.

Shielding gas is needed for Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW). In this video we go over the following:

0:00 Intro
0:09 Safety
0:43 Cylinder date markings
1:50 What type of shielding gas should I use?
3:40 Regulator flowmeters
6:20 What size cylinder do I need?
6:50 How much do welding cylinders cost?
8:12 How long can you weld on a cylinder?

Another great video!! Been wanting to get away from flux core welding and this really helped me understand what it takes to weld with gas.

In CT the going rate from Linde gas (Praxair)
330cuft c25-88$ exchange
Letter K oxygen-31$ exchange
3.5 acetylene-134$ exchange (was up from around 80$)

Hello, I have two questions, please
1: For MIG welding, when to use co2 gas and when to use argon gas
2: Does co2 gas affect the properties of metals ?

Another well executed and very helpful video. Thank you!!

[markveldhuizen]

Great video. Thanks! Helped me learn a lot.

[eelson]

Just the info I was searching for thanks!

[itzironlifemiguel]

What strap did you use, do tie the gas cylinder? Is it safe to be sideways or should it be upright?

[MySpam-vt]

can you show a video how you transfer gas between the steel and aluminum tanks?

[danielchambers]

Great video Sir….. useful info as well….. thank you Tim for helping the hobbyist ✅👍👌

I have a smiths little torch for silversmithing - I use a #1 oxygen bottle with regulator and flash arrestor. Seeings how it seems the most dangerous moment is turning the tank on, would it be safer to just leave it always on? I use my torch every day.
Great video, thank you 👍🏻

Great stuff! Just gotta keep my eyes peeled and hopefully pick up a cylinder for cheap on Craigslist.

Thank you for the video. I have an argon/co2 regulator .Can I use it with Nitrogen gas since fits to tank if I change the left low gauge to 100-600 psi one? Thanks.

[leslywilliams]

what if your tank of CO-2 finish now the tank is empty can you put Argon and the tank instead use it what I am trying to say is.Can you use the same tank over and over with different gases when it finish or when it's empty

[TheMiniMachineShop]

Just bought a new full 75/25 and the gage says 2, 2oo psi is that full?

[RichSobocinski]

Question about filling the tanks. I get it that if you rent the tank you probably just bring it in for an exchange. What isn't clear to me is if I own my own tank, am I getting that one filled or am I also getting an exchange (though probably at a lower cost)? I ask b/c you kept using the word "exchange" and the tank you showed at the beginning wasn't the same as later in the video. Please clarify. THanks.
