if i use stright aragon will i be able to mig mild steel sucessfully with a change of wire? im looking for the best all around combo of gas if that exists. i would like to weld stainless, mild, and possibly aluminum but i read that aluminum doesnt mig too well.

 

if you want to mig aluminum get a spool gun. don't even try feeding it through the line like steel wire. It will just bind up.

 

SS wire, what thickness wire should ya get for the exhaust... i know their is different sizes and don't know what is best.

 

I wanna know this too. I'm going to be doing a lot of welding this summer and some of it is SS, everything else is MS.

 

I forget the 100% answer, as it's been a while since I did much mig. I'm about 90% sure you can. I prefer 92%argon/2%oxygen, as it adds a lot more heat...but I don't think that lack of 2% oxygen would cause any problems with it.

 

 

i bought some gas here they call stargon lits 25 co2 74 aragon 1 oxygen i dont have a regulator and ran some ss with the flux core.. wish i didnt buy the gas now

 

how'd it turn out then?

 

If you don't care about rust, just MIG away! At least thats what I have been doing. I am using a 110volt welder, with .030 wire and 100% CO2. And the welds are pretty damn good (once I finally learned how to weld that is). I was welding the stainless IC piping, and some stainless exhaust.

 

it turned out alright doesnt look too bad im pretty new to welding. i cant see in the pipe to tell if it got good penetration but its holding well
