Subject: Argon pumping (was Helium & O2 grading was Gobber Grade helium)
Hi Ingemar
I use the garbage bag method, a plastic bag is lashed round=20
the outlet of the argon bottle and a hose from the bag to the
compressor inlet=2E Open the argon just to fill the bag and start
the compressor=2E Then add argon manually to keep the bag
suitable inflated=2E=20
BTW, has anybody experience with argon/CO2 mix for drysuit
inflation? Some people I met used 23% CO2 with good results
(good insulation and no itching )=2E This mix is available as=20
welding gas=2E
