Stupid Tig question..blush

i'd have to guess you got a leak somewhere in the line that the higher flow rate was sucking (vacuum) air, though it does not take much air movement to compromise your shield, and what you're describing would have been the result...

Hummm ok. my welding bench is outside and there was a breeze of sorts.

So what are the issues and signs that arise when your sheilding gas blows away? Ferrous materials of course.

Obviously the electrode is not effected, but the weldment......

Thanks

My guess is porosity. The shielding gas keeps oxygen out. If you're losing your shield, air will get in an oxidize the metal and cause porosity. But, I'm a FNG so I could be full of crap. Can someone confirm (whether I'm right or wrong...most people tell me I'm full of crap :))?

Gunner, Did you get my E-mail I sent you about relocating to Long Beach? I never got a reply. I sent it Sunday.
