  • Are these small oxy-acet tanks any good?

    My Grandpa had these, he got them from the local blacksmith when he closed his shop. Hoses are trash, regulators probably are too. I would need to transport them 400 miles to get them home, otherwise free tanks.

    I can gas weld, but only have a single car garage to work in, so small is good. I also can get good hose and a mixer with a few tips with it. Would be a nice compliment to my small MM135

    Acetylene tank has about 275psi according to the gauge.
    Oxy tank is empty

    Numbers on the Acet tank:
    X685668B 34-2 ICC-8 3T 48 (any idea what date?)

    Numbers on the oxy tank:
    DOT-3AA 2015 REE:20.3
    A 195052 <c> 8A92 +* (last character is a star)

    Though the oxy tank is very small, it looks like it is good with a 2015 date. I'm not sure what sort of a hassle it would be to fill the acet tank when it is empty, or if it is a concern to transport it 400 miles with gas. They don't have tank caps or threads for caps either.

    Attached are pics, I have more, higher res if needed.

    Let me know your thoughts. Thanks!

        First off the oxy cylinder is a 20ft, the acetylene cylinder is a "B" 40ft it is full There are no caps on that size cylinders. In the rack they are in if you can transport it tied down not in the passenger compartment, van body or trunk By all means the cylinders run between $60.00 and $100.00 each. The rack holder is close to $100. at the LWS The regulators may still work if the knob or T handle on the regulator was turned out and loose, the diaphragm didn't have pressure on it. Hoses are cheap.

        If you can transport them in the up right position the is less likely hood of damage to the valve bodies, by falling or rolling items.

        The only statement I will make is if you plan on doing any cutting with a torch you will blow thru about 3 to 4 oxy cylinders to one acetylene

            If they were mine I would take off the regs & make sure the valves are closed for transport. Other than that load them up & go. If you got a pickup just tie them in the bed. If you stick them in a trunk you can tie it open some for venting if your worried.

            The oxy bottle is small, I would keep my eyes open for a 80 cu ft. & buy it. Then sell the little one or keep it as a spare.

            IMO worth bringing home.

              The small cylinders are quite handy. Good deal for free, and by the looks of the adapter your acetylene regulator has a CGA-510 fitting which will screw into a BBQ propane jug.

                i have a couple of the small oxy bottles like the one pictured and i asked the lws about filling or exchanging them and was told they couldn't do it because they were not rated for (pretty sure they said)2450 psi. may be different in your area.

                  Don't have a clue what your LWS counter person is talking about They are standard DOT approved standard cylinders.link to everything you need to know about acetylene cylinders



                  Numbers on the Acet tank:
                  X685668B 34-2 ICC-8 3T 48

                  Numbers on the oxy tank:
                  DOT-3AA 2015 REE:20.3
                  A 195052 <c> 8A92 +*
                  Are the DOT stampings numbers,
                  All high pressure cylinders are tested to a pressure slightly under 3360 psi Which is the pressure the rupture disk in the valve lets go at.

                  The acetylene cylinders are low pressure cylinders.

                  2250 PSIG @70F for oxygen is considered a full cylinder
                  225 PSIG @70F for acetylene is considered a full cylinder
