Which type of gas to use? Beginner.

[H80N]

yes it is! lol

COOL,,,,,

Just Curious...

is

"Baktc" for "Back to Sea"......

yes it is! lol

Thanks Ja for the correction.

Just Curious...

is

"Baktc" for "Back to Sea"......

Sometimes "simplified" removes the meaning of the lesson...

that chart loses the "WHY" as to the use of the various gasses and mixes...

it is very useful for the weldor to understand at least a little of the physics of the interaction between gas and metals being welded..

Keep a copy of the manual for reference... no need to swallow all of it in one sitting... that is part of the beauty of having free PDF technical downloads..

AND...

as far as tradenames... it seems that the suppliers like the confusion for marketing purposes...

However... simple solution is yet another Free PDF download... "Cross Reference"....

that should remove a lot of the mystery...

Yea I would like to know why which gas works best with which material and understanding why it is that way! I will download both PDF's! Thanks for the help!

Im I missing something? swap your polarity for aluminum? Did you mean flux core wire?

you are correct...

maybe his world is flipped ....

[ja baudin]

Just give him the dam answers to his questions
Mig welding.>>
Stainless steel uses trimix gas.
Aluminum uses argon. And
Mild steel uses 75/25 argon co2 mix. .
On aluminum dont forget to swap your polarity

Tig all straight argon. 100%

You must live in a very simple world...

too bad the real one is not always that straightforward...

Certainly no arguments from me. Fundamentals is fundamentals, and understanding the "why" is usually the key to figuring out and solving problems.

That cross reference .pdf is very nice. Thanks for that link!

Too Simple to be useful...

Reading the Praxair guide can be like drinking from a fire hose. Also, their proprietary shielding gas names and mixtures can be confusing at first.

Here's another, more basic discussion with a simplified shielding gas chart that might get you going faster:

Across the top of the table are the welding processes and the column on the left are the common materials.

Hi, I am new to the site and also to welding. I have a question about which type of gas to use with different materials. How do you know which type of gas to use with a specific metal? Such as stainless steel, or regular steel, and so on? Does it just take experience working with those types of metals that you eventually learn what goes with what? I am confused by this. Thanks a lot and I hope to here from some of you..

The Praxair Shielding Gas Manual..

will explain the why's and wherefores of gas selection...

here is the link to download the PDF..
