yeah bin them dont buy them again
get a contract bottle either hobby weld or a boc gas account via the volkzone offer
I opened up the torch and took the gas pipe off then took the end off the bottle. I then blew through the pipe and placed the other end in water and there were bubbles so the pipe isnt blocked. i then put the old regulator back on and i had to really force it round to get gas top come through but eventually it did. The next thing to try will be to take the valve off and have a look at that.
please note hobbyweld isnt the only place that supply argon gas
an old thread but gives you an idea that other places do supply it and also an old price reference
