hi guys,
i've done some steel and fair amount of aluminum tig welding, and i've got a couple of projects coming up that are titanium.
i'm not sure if i should get one of those inflatable purge chambers, or build my own out of lexan - or just get a trailing shield and some tape and purge the pipe, tape it off and use the trailing shield.
what have you guys used? what do you think is easiest to deal with?
