can an oxygen tank be used as an argon/backpurge tank?
i only ask because harbor freight has this tank on sale for $59 right now. it looks identical to the argon tank that is 89 its just the outlet looks to be inversed. i am assuming if i used a oxygen regulator it will work. thats if the gas place allows me to fill it with argon. the tanks thems selves are not labeled gas/oxygen.

if you already have one tank, you could get a dual regulator and not have to worry about a second tank.

a tank that size will run out really fast.
i use 125s for my purge. its a worthwhile investment.

as far as the tank size it wont get much use., until i am in a shop setting where i might use it every day this size will be ok. as far as mutliple tanks they will probe be different mixtures. tig/mig/back purge. should the backpurge be the same mixture as the tig setup?

yeah, just T off the main bottle. i don't feel there is a need for a second bottle. you can just use a small needle valve to regulate flow for the purge line. that's what i do and it works. unless you are doing purge work all the time, it isn't worth the extra rental cost as well as regulator cost.
