84/16 steelmix gas for MIG

i talked to the guys at airgas about the 84/16 steelmix
they said it would make my life easier on the thin stuff
(compared to the 75/25 that I had been using )
so thats what I got

did I screw up? anyone else use it?
I remember it was mentioned by someone in a thread a while back

i have been searching the interweb all morning and cant find any real solid info

but with stuff I have found, it still looks good on paper

Never heard of it, I've always used C25 (75/25). Keep us posted!

the more Co2 , the deeper the penetration,
(a cheat for using too small of a welder on thick material is use 100% Co2)

so my thinking is...
less Co2 should help to not burn through the thin stuff

or is my thinking off?
I am sure its not that simple, and there is more to it than that

You probably didn't get hurt as long as they didn't charge much extra for it but I doubt it will help with the thin stuff very much. There are all kinds of gas mixes out there, some even have more than two. These tri mixes can even have small amounts of Oxygen which seems to be a contradiction but in certain conditions it can help, usually these exotic gases are for industrial use and the main concerns are speed/production costs more than anything else. Most of them will work just fine for the type of welding you are doing however and unless they charged you a big premium it should not matter much one way or the other. Actually depending on your welder, the wire you're using and surface condition you may very well see a slight improvement, or not, but I wouldn't expect it to be anything to get excited over.

75/25 has been the standard mix for many years and every ratio possible has been tried but the old standard C25 has always been the best for all-around use for a good reason,

i am not expecting miracles, but while im welding these patch panels etc.
i am thinking every little bit would help, me and the thin stuff dont see eye2eye
