I will avoid the discussion of the purge or no purge. I will just give two suggestions regarding the protection of the root, N2 (azote) is a lot cheaper and does the job just fine for purging. For purging only, it can't be used for shielding! Another option are the flux tig rods that do the same job as the solar flux. I will check the name in a few minutes, I'm on my phone and I don't remember the name but they are expensive
