First off I wanted to say Thank you for what you have posted I have learned a lot. Probably the best tip was going to a gas lens set up Helped my tig work immensely. But now I'm having some issues that I haven't seen covered yet. I and assume some others are having trouble when welding tube that will be sealed up when done (as in both ends of the tube are capped off). when I get to the end it seems like the pressure that has built up in the tube keeps pushing the weld out of the seam and filling it with unshielded gasses so I get porosity. any help would be appreciated. I don't seem to have trouble with the mig or maybe I don't notice it as much but with the tig it's getting frustrating.
