hi brett yes watched them do everything, they fill on the scales so you can see whats going in. They use a pumped system so they shouldn't have any probs at all but they just couldn't get any more in.
I suppose they could have run out (of liquid?)
More of a concern to me is where my surplus weight(liquid) went. not whether these particular vendors have difficulties of their own, after all they put in 5lb and i paid for 5lb
I acquired a nice new WON 11lb bottle (that i'm hoping to exchange) this week and its identical to mine... except "pie" mark so mine is an 11lb er.
I hooked my defective bottle up to my gauge and got about 350psi. got the"fairy"out no bubbles. so no leak
then last night my TIG welder died, disconnecting everything to ship for repair it dawned on me that i had a cheaper (than n20) pressure source with which to check to working pressure, 1500psi of argon.... GUESS WHAT!!!!!!
YEP AT 500psi I'VE GOT A LEAK very small but obviously enough
Tap out,clean "o" ring and mating surfaces and sorted.
No more leak
looks like i've solved my own problem. if anyone thinks there could be anything else going on don't hesitate to let me know. All this learning the hard way could get expensive, i guess i should be grateful that they could only get 5lb in.
WE live and learn right off for a refill
Keep up the good work folks
many thanks, just a couple of little points to clear up, as this 11lb bottle is only used for storage/filling small bottles.
