A buddy bought his kid a CO2 setup to fill painball marker cylinders. I guess they use compressed air now, so I am the proud owner of this setup I will probably never use. Anyhow, I would like to use up this full cylinder of CO2 with wire. I was just wondering how far you have to tip it upside down, and does anybody have an idea of a quick stand I can make to hold it there safely?"Where's Stick man????????" - 7A749"SHHHHHH!!

Reply:Maybe I'm wrong, but I think you want that tank right side up so's to get gas, not liquid. MikeOl' Stonebreaker "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw
Reply:Hi, as far as I know, and for C02 that's not a lot, you'll need a heater for the regulators or they'll freeze up and block your gas flow....just my 2 cents worth....my mate reckons you could use the gas for blowing dust out of your welder gear as it's dry and very clean.....especially the circuit boards etc.Ian.
Reply:Is it a dip tube cylinder or just a regular one upside down.Experience is something you get right after you need it
Reply:I run CO2 for all my wire, hard and dual shield, no special heaters or regulators needed. I think if you tip her up past horizontal you will be fine, or trans fill a 20 pounder till it is empty, then remove the dip tube before you get it filled again.Disclaimer; "I am just an a$$hole welder, don't take it personally ."
Reply:Sorry guys, I forgot to repeat from the title that it was liquid withdrawal. I do have a 10# and a 20#, compliments of my HVACR pal. But what kind of setup do I need to transfer it? I probably won't need to do this again, but if the stuff is cheap enough I don't mind. Tozzi, I was really thinking of getting used to CO2 for hard wire insted of C25. Man, that would be sooo much cheaper. But C25 comes out so nice. I am going to play with it. It would be nice to just bring the 10# or 20# to a mobile job. Do you just use the small ones on the truck and do you refill your own all the time?"Where's Stick man????????" - 7A749"SHHHHHH!!

Reply:I keep 2 20 pounders in stock, I just swap em' out at the LWS for 10 or 12 bucksDisclaimer; "I am just an a$$hole welder, don't take it personally ."

Reply:Lay it on its side, will get the gas out. If the temperature is over ~80 deg, there won't be liquid no matter what in the cylinder.Experience is something you get right after you need it

Reply:That Hobart setup is actually a regulator and hose for hooking up that paintball cylinder to the mig. I am looking to transfer cryogenic liquid, so I've been told. I have talked to Western Industries and some other manufacturers with no luck. I didn't realize this would be so difficult. I am making a few more calls this morning, I'll let you's know. But my HVACR buddy found me another 10# cylinder to give me. I picked it up last night after school. He said there's no telling how many more he has in his garage.As he cleans and finds them, he will give them to me!"Where's Stick man????????" - 7A749"SHHHHHH!!

Reply:Stick-man, you might try the local paintball shops - with attached play ranges. They have all kinds of connection kits. True what you want to do is different but they still may have a 'kit' or be able to show you what you need. You could also try goggling - might have to get your search phrases just right.The cylinder you have (liquid dip) is what the paintball shops use for filling the small aluminum 8, 12, 16 and 20 oz paint ball cyclinders. It should work fine too for filling larger tanks. Still if you just want gas for welding, you may be able to just swap it out for a non-siphon dip cyclinder at your local gas supplier.Rick V 1 Airco Heliwelder 3A/DDR3 CTC 70/90 amp Stick/Tig Inverters in Parallel1 Lincoln MIG PAK 151 Oxy-Acet
Reply:I've filled hundreds of 2.5, 5, 10, 20 lbs co2 cylinders. I have never flipped a dip tube tank over. I think that would work. You can as someone mentioned "offload to a smaller (or same size) non dip tube tank. All you have to do is run a hose from one to the other (i dont know how expensive the hoses are) . you will only get whatever size tank you choose about half full/empty without a pump. But you can do this until your tank is empty.www.performancealuminumfabrication.com
Reply:Transfill whips are easy to do.A pigtail of desired length from Western Enterprises with 1/4" NPT female ends, a nipple and nut for the "feed" cylinder, and a nipple/nut or fitting for the receiving cylinder. All available online without leaving your house.http://www.westernenterprises.com/en...gen.php?gid=12Google for best prices on standard lengths. I don't care for "crimped-on" nipples because I want to be able to swap ends.http://www.overstock.com/Home-Garden...7/product.htmlhttp://www.bettymills.com/shop/produ...12-6-CO-4.htmlDon't forget a CGA-320 adapter to connect the cylinder to a CGA-580 regulator. Cheap.Once you get set up you can have large cylinders at home and fill portables to your hearts content.You can also transfer argon and mixed gas with a CGA-580 pigtail. HVACR folks do this with nitrogen (same fitting) all the time. I just scored a bunch of nitrogen cylinders and am having them hydro'ed and refilled with 75/25 and argon. They are CGA 580 valves so no problem.Be "wise" and gobble up many cylinders!

Reply:Hydraulic hose of suitable pressure rating is fine for inert/mostly inert gases. NOT oxygen, it bears reminding for others who read this.I transfill oxygen (separate dedicated oxygen-clean hardware) and inert gas and LP (filling small "disposable" cylinders). It's easy, convenient, and quite handy.I haven't done liquid CO2 to vapor cylinder yet due to lack of need and no liquid CO2 source. Theory is the same.Invert liquid withdrawal cylinders so da dip tube "isn't dipping" if you want vapor.(In the case of LP, you invert VAPOR cylinders so you get LIQUID.)Pigtail plus rated high pressure fittings equals transfill whip after which the only question is "cylinder upside down for vapor withdrawal" or "down for liquid withdrawal". Western sells fittings, not dedicated rigs. What I do when transfilling oxygen and MIG gas is use suitable Western "manifold" tees so I can plug in my welding regulators to read pressure and vent conveniently. Tees are about 25 bucks. You could use 320 pigtail plus 320 tee plus "320 to 580 adapter" and be golden. Put the regulator on the VAPOR side.and does anybody have an idea of a quick stand I can make to hold it there safely?
Reply:Edit for clarity:If you want max fill to vapor cylinder from from a liquid cylinder, withdraw liquid into the vapor cylinder since the liquid will turn to vapor for withdrawal for USE from the vapor cylinder, as does LP.You can have vapor from an inverted dip tube cylinder, vapor from a normally oriented vapor-withdrawal cylinder, and liquid from an inverted vapor-withdrawal cylinder, it's all about which way they are pointed!
Reply:For compounds which are liquid at these pressures like the freons, LP and CO2, if two cylinders are connected by a high-pressure hose and one cylinder containing the liquid is put in a warm place such as a dark box in the sun while the other empty cylinder is put in s cooler place such as a hole in the ground or a small refrigerator, then the two cylinders will be at essentially the same pressure so the liquid in the warmer one will boil while the vapor will condense in the other. I have transfilled bottles this way before. It is possible to overfill a bottle by this (and previously mentioned) method(s) resulting in there being no space for expansion of the liquid when the cylinder later warms. Some cylinder valves (IIRC, CO2 included) use burst discs rather than spring-loaded relief valves (as with LP) so an overfill and later overheating can result in all the gas being lost, together with whatever problems the escape causes. This should be considered when filling any cylinder.
Reply:High pressure cylinder valves such as the typical Sherwood use burst discs.

Reply:Seeing as how you are getting several small cylinders, you may want to get a high pressure regulator for them so you can use the CO2 for air tools, spray guns and airing up tires on the job. I usually get the 150# and they cost around $35 at my welding supply. They are a set pressure when you get them but you can change the springs in them to get other working pressures.

Reply:Originally Posted by Stick-manHey, can you give me a brand, make, model number on that 150psi reg for $35.00? I want one for an impact wrench for road trips. . .
Reply:I use a Western 200 psi fixed output reg and a long hose to act as an "accumulator/evaporator". Works better that way for impact and tire fill.http://www.westernenterprises.com/en...reg_preset.phpThe RP Series Preset Pressure Regulator models are designed to supply a preset pressure for portable CO2 applications. The economical design offers pressure selection from 30 PSIG to 200 PSIG. |
