Purging - Dual Flowmeter or use a "T"?

[B_C]

I use a SEPARATE bottle for purge gas.....that way I can set the CFH flow at whatever I need to get the vessel full of Argon with out flowing gas through my torch....And if I run out of weld gas it still is purging the part....Some parts are very expensive and I don't want to buy a $$$$$$$$ part because I burned it from lack of purge gas......Whatever makes you happy, but that's how I do it...

Thanks, B_C. That makes sense.

Got spoiled working in that Semi-Conductor industry.....They don't take any chances since most of their product line is high dollar stuff....

Question for you boys who do aluminum marine fabrication (SundownIII, FusionKing, et al):

When you're fabbing aluminum frameworks, do you purge the inside of the aluminum tubing, normally?

I'll guess the answer is no.

I never have.....Aluminum doesn't oxidize like ferrous metals......
