Just exchanged full (75% argon, 25% co2) "S" size cylinder has 14 stamp which means its good for 10 yrs before next test I would've sold the old empty but its pressure test stamp was expired it had sat idle so long (i just don't mig weld that much anymore) The same thing retail will cost you $225-250 local pick-up only
bump...$180...if you've been wanting to upsize your mig bottle or want an extra on hand for when you run out mid project, nows the time!
