NEON- Re: oxygen in neon fires, Neon-l server was down
IO.com's upgraded their mail server (which I believe neon-l goes thru)
this weekend. They had major problems, and mail is very backlogged.
(I've been without email for 3 days). Things should be getting back to
normal by the time you read this.

I find this the biggest advantage of adding oxygen. I've added small
amounts to both a cannon fire and a BMT-7 ("splicing") fire. With such,
the flame is quieter, smoother, hotter, and there's significantly less
"splash" -- I can have my fingers almost 1" away without getting burned.
Very nice indeed.
But it's too costly for me with the above burners. I have a small tank
hooked up to a HOKE torch for tubulating, fixing holes, and general
cosmetic retouching. I've wondered how good those oxygen generators
are. My understanding is that the output is about 80% pure, and they
work by forcing air thru a filter of sorts that lets mostly O2 by. This
might make it practical, but I bet they're expensive?
And a question for Dirk: why would one NOT use "blowers" for neon, but
compressors instead? You say only 1 shop in Holland is using such.
Blowers (and I'm thinking regenerative-type here) are quiet, oil-free,
non-pulsing (no buffer tank needed), and very reliable (1 moving,
non-contact part). There was a shop here (until they burned down a few
months ago) using a giant compressor as the air supply. Seemed
wasteful: a 5 horse motor and it just barely did the job.
