Why can't you use the same gas for MIG and TIG? #welding #shorts

For those wondering, the reason you need to use the proper gas for the process has to do with the chemical reactivity of the gas and the metal you are welding. Argon and helium both have full outer electron shells and as such, aren't going to react chemically with your puddle, or in the case of GTAW, your electrode as well.
With aluminum GMAW you'll need to use 100% argon as well.
Because of the chemical composition of mild steel, you can use CO2 for short circuit or globular transfer modes, but for spray transfer you'll need a gas mixture that is at least 80% argon.

Newsflash: the "I" in TIG and MIG stands for INERT, most commonly used inert gas is Argon. For MAG which uses an ACTIVE gas, you usually go with some mix of Argon and CO2, usually 82% Argon with 18% CO2

That's a really nice song, I love it !

Was this video shot in HDR? It turns the brightness up on my screen, looked into it and it's apparently from being shot in HDR. Turning power saving mode stops it. Not sure why it's even a thing, most people want the brightness set at a comfortable level, not to be blinded while scrolling lol.

What kind of gas so you need for stick ?

[Oneshot]

What metals are you welding? CO2 is an active gas, and wouldn't be used on, say, stainless.

who said i can't aluminum tig or mig 0.003% NO.. with argon?? heck id like to see aluminum mag .. lol
