40cf c2h2 tank 200psi (missing knob, I used a wrench to test)
That is more commonly referred to as a "B" size Acetylene tank. And
they don't come with a knob, you use a little dogbone wrench to open
them. Put a piece of small chain in the other hole and loop it around
the regulator to keep the wrench from wandering away.
Heh. Now I can say I know more about something than the guy I bought it
from.
The trick is not to let the seller know /you/ know until after
you've agreed on a fair price - they might smell blood and raise the
price out of the reasonable range. Then you have to explain the next
paragraph to them.
I wouldn't by jack from someone like that.
I like being open about everything, including my ignorance. If he isn't
the same I probably wouldn't even find myself looking his stuff over.
He offered me a fair price, told me the new price (three times what I
paid... for the welding kit minus the tanks and cart.) and explained his
pricing for the tanks (the cart was a gimme.)
Unfortunately, this makes it very difficult for me to find a mechanic.
A fair price to you may sound low compared to retail prices for the
same item new - but it isn't new, and has no warranty. If it turns
out later to have a problem, you paid too much for something that'll
have to be tossed, or need replacement parts, or to be professionally
repaired, so in the end it all works out.
There's the heart of the problem, I didn't know what a fair price was,
and so let him give me one. I felt comfortable doing it, too.
And you do NOT want that Acetone level to run low inside the
cylinder, or the pressure past the regulator to EVER go above 15 PSI.
Google "Acetylene Deflagration" and learn. (It just decides to go
BOOM!!! and levels the garage - this is not good...)
Jeez. I think I've not been cautious enough. Thanks.
Everyone needs a wakeup call sometimes - preferably not a fatal one.
I was talking in the round, of course. I never pushed the pressure
beyond what I found printed in the manual and user notes, but having
read all the BAD things that can happen with this kit, in this thread,
I'm wondering how long I have to keep it alive to get them all.
Or, be a little more focused and diligent while reading the manual.
[transporting tanks in a car]
There are photos out there of wonderful free-form metal sculptures -
that used to be a car or van before a cylinder went off inside them...
"Awesome Blossom", indeed. ;-) The Welding Supply probably has one
or two on the wall to point at when people wonder why they refused.
Just google'd up a very recent example for you -

Heh. Google images is your friend:
http://www.nasoceana.navy.mil/safety...neincident.htm
I have no intention of storing the tanks in a car, and I'm pondering
some form of protective covering for the valve (these lack threading for
a bell cover). Even if it were a neutral gas this would be a danger...
But they are always (when I'm not (in the future) hauling them to the
supply shop) in a cool dark place, and I'm only (now) using them outside.
My fear is not knowing the more esoteric dangers inherent to the
equipment. Must read more...
