Argon pricing???

[Rambozo]

Wow, I paid $225 for a full bottle, including the bottle... $40-$45 for a fill

So for that Hawaiian experience, just throw away your bottle when it's empty and buy another one.

I just upgraded from an 80 to a 150 the price difference was nominal.

Pumps
Haskel booster pumps have oxygen pump and none oxygen most of them oxygen compatible. The best one is AGT-15/30 it will pump to 9000 psig sounds high but you need it because it will pump the tank empty and fill your tank to 2500 psig from a low pressure. All the pump have area ratio so 15 is 6.2 cu.in. 30 is 3.1 cu. in. so it takes the 15 and pumps it into the 30 then out. Yes the the smaller the number the bigger the pistion. A place to find pumps cheap some times https://www.govliquidation.com you bid on them good old USA Military hunt for words as BOOSTER, HASKEL, SPRAGUE, CURTISS WRIGHT and PUMPS sooner or later they will show up. I will be selling some of mine next year just got to many like 9 pumps you bid on them and you get 3 in the lot some good or not make one or two good ones out of them or you get lucky and they are all good or bad but there are usually OK just need a little work.
