does it look / handle any different using Ar / N2?
Evidence I have seen suggests lose about 2% to 5% ferrite when TIG weld with straight Ar. That's metallurgical - but as a welder-ther-person do you see a difference? Rich S
Honestly I haven't welded much of this, I don't believe there is much of a difference.
