when i've welded gas tanks, they get a good rinse out, then i'll blow the fumes, i use a long 2 core wire, the ends are joined with a fuse wire, or a few copper strands, then i connect a car battery across the wires at the other end, at best there's not been an audible bang :(
usually not that much, maybe a puff of smoke.

an army friend did the first one for me, and i've been doing them the same way, although i'm a LOT more cautious than he was
i've done 8 maybe 10 this way

Anything the puts off smoke or goes pop or bang should be avoided.... Inert gas is best....
