Argon?

Just wondered if there was a magic blend.

I haven't gotten that far yet. Got an inverter stick machine that has a switch for TIG. Haven't gotten around to getting argon or a regulator though. I figure it would be a little difficult for me.

Argon. Back purge is sometimes helpful to prevent sugaring.

Late to the game... Always 100% argon for any procedure and I suggest a Yeswelder bubble gage regulator. They are graduated in SCFM and cheap on Amazon.

TIG is always 100% argon. MIG can let you experiment with different gas mixtures depending on the wire that you are using and the quality of welds that you can accept. As for back purge gas on stainless, Nitrogen can be used instead of pure argon if you want cheaper option. It is a bit harder to purge all the air out due to it not being as heavy as argon, but it will work well once you displace all the O2.

I only run 75-25 on MIG solid wire. No exceptions unless it's flux core which I never use.
