Victor portable Oxy-Acetylene kit - tip selection?

I have a small Victor portable Oxy-Acetylene kit. The one that comes with the 10CF Acetylene and 20CF Oxy bottles. It came with a Victor 100FC handle.

It also came with a #0 cutting tip and #0 welding tip. According to the tip chart, the #0 welding tip flows 2-4 CFH.

I was looking at what my choices were for some larger tips and it seems like if I obey the 1/7 flow extraction rule - I really shouldn"t even use the tips that came with it!

To stay below 1/7 (1.4CFH) I should only use a 00 or 000 tip.

Am I reading this correctly?
 
He has acetylene, and yes your tanks are too small to use a cutter on. Short work will be fine, but bigger work you will spend all of your time changing bottles anyway. You can use your regulators on bigger tanks with an adapter.(AC)
 
You can exceed the 1/7/hr. for short periods but unless you're hiking your cylinders up a 300 ft. incline, get some bigger cylinders. The refills on the small cylinders will cost you a fortune!!! A 75 cu. ft. acetylene and a 122 oxygen would be a good size and are still fairly easy to move around.
 
Bought one of those sets for my Son. Got a fitting to equalize the oxygen from a bigger tank. Changed the acetylene bottle for a LP bottle. Can fill the LP from my big tank. (I made the LP tank from a 3" pipe with a almost 1/2 wall. then welded 1/2 plugs in each end put a regular LP Grill bottle valve in the end. Works good. Can carry it anywhere. It always has had enough gas and oxygen to complete any repair for the last 5 yrs or so.) Maybe you can find a LP bottle the rite size, to go in your carrier. Always let it equalize before we use it.

You do realize your homemade LP tank is highly illegal? What do you mean by equalize? Filling smaller cylinders from larger ones is fairly common with the right apparatus but once it's filled, you don't have to wait for it to equalize.
 
I guess I lied about it. The LP tank. It takes a while for the oxygen bottle to get the same pressure as the larger one. Kinda like filling a tire from a air tank.

Actually, this small kit is perfect for my needs - which is what led me to choose it in the first place. It came with a cutting head which I have used several times and it works fine. I was simply looking at adding a larger nozzel for a small job and didn't stop to think about the limitations of the 10CF fuel cylinder delivery rate. It's no biggie - I will use something else.

The larger bottles would be a bit large for my needs. I don't think I would be able to toss them in my car trunk for transport.

It only costs me $21.50 to refill the Acetylene bottle, $11.30 for the Oxygen and it lasts me almost a year.

I appreciate everyone's feedback.
 
It's about volume. It shouldn't take long to fill a 20 cu ft oxygen from a larger cylinder unless that cylinder isn't much bigger or is low on pressure. The volume of a tire is much more than the air tank. The size of the orifice makes a difference too.
 
If you carry cylinders in the trunk of a car, the small cylinders would be more than enough to cause a big explosion if something happened. Equal parts oxygen and acetylene in a styrofoam cup has a pretty big explosion when ignited.
 
When you toss cylinders in the trunk of your car, you should toss the acetylene in standing up. I was always told when you lay an Acetylene cylinder down you should not use it for 24 hours so the acetone can settle back down to the level it is supposed to be at.
When we would high line cylinders from ship to ship we would not use the acetylene for 24 hours. I am sure you know not to use an acetylene cylinder laying down.
 
Yes, you are correct. The cylinders need to stay upright. Which is why the small bottles are nice (for me). I transport them in the plastic tote that came with the kit. It keeps them secure from rolling around or banging into each other and I am able to keep them upright.

Obviously anytime you transport compressed flammible gas you need to be as careful as possible as there is always risk - much the same as when you transport 20 lb bottles of propane for the gas grill.

I always try to drive directly to and from the gas distributer with no side stops to minimize the time in the car.
 
(quoted from post at 00:22:37 01/13/13) If you carry cylinders in the trunk of a car, the small cylinders would be more than enough to cause a big explosion if something happened. Equal parts oxygen and acetylene in a styrofoam cup has a pretty big explosion when ignited.

So what's your solution? If you need torches, you need to transport cylinders full of flammable gas from time to time.
 
Use a truck? I was merely pointing out that if
there was a leak or other problem, the small tanks
would be more than enough to cause a big
explosion. The OP suggested that the smaller tanks
were safer, which isn't the case. Propane tanks
shouldn't be carried in the trunk either. Even dry
ice shouldn't be carried in a closed space. If dry
ice is in the back seat of a car, all the windows
should be open. Welding trucks even have to have
vented cabinets and the cylinders have to be
capped when being transported. A lot of guys leave
the regulators on but they could get a big fine if
pulled over.

I've seen cylinders carried all sorts of ways.
It's quite a job fitting a 337 cu. ft. oxygen into
a Chevette. Every once in a while a customer
brings a cylinder in to exchange and forgets the
cap. Then they get upset because it's a $10 charge
for a cap so just want to exchange the cap with
the full cylinder. What they fail to realize is
they're carrying a bomb with 2200 PSI! If they
bring the cap back the next time, they get their
$10 back.
