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..

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.

Too Simple to be useful...

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...

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!Comment

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%.

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!Comment
