Humm, CO2 is sometimes used as a shielding gas in wire-feed welders...

I'm very low on Nitrogen. What would happen if I used CO2 to flush out the air?
And trickled CO2 slowly while brazing??

Would it cause some horrible deposits to form inside the copper tube?

I have about 10 pounds of CO2

(Don't tell Al Gore)!
