Out of interest how long would you expect to get out of a hobbyweld 9 litre bottle of argon.
I only got 4/5 hours welding, admittedly it was my first time with a tig, but even so it shocked me
im about to start trying to learn to tig weld myself and was thinking the same ! am i right thinking 10l@200bar is 2000l so divided by flow per minute is weld time ish ?
I found the "hobby" cylinders empty a lot quicker than the boc ones, I found it worthwhile to get onto the volkszone deal with boc ! but depends on how much you are welding , I haven't done any for ages !!!!!
Hobby weld bottles are only 137 bar too, so less in there than there would be in the same size bottle with 200 bar in it. The sgs gas ones and boc are filled to 200 bar.
cheers both , the bottles are sgs, i already have a mixed sgs and the agent is very convenient so i went to them for the argon ! i think i will use a fair bit at first playing and practicing but then it will probably drop like the mig did ,if not it could be time for a change to volkzone
