    Somebody NOT telling you truth.
    How could such a practice happen in the welding supply industry? Especially the gas end of the business?

    Maybe it's just a rumor they started to keep the fill crew awake.

    Threaten to hijack a whipped cream truck.

    Better yet, pipe some into the opponent's pit and see if the crew gets silly.

    N2O had no additives other than perhaps iron from a crappy cylinder.

      we filled small cylinders everyday when i was at the LWS. Filled from 6 or 12 300CF bottles and a hose like what Noel posted. Never bled them just hook up and go slow. The 300 cf were hooked together in series and just crack one from lowest psi on the 6 and go. Then close the first one and open the 2nd one up the line until you get the pressure...Bob

        I wasn't going here when I asked about cylinder sizes, but since the subject of lifting and carrying them lovely things came up; I'll mention that I am as close to rockin chair lazy as a man can be when it comes to moving cylinders. I got no problem whatsoever sittin and watchin somebody else move them. Occasionally however I do have to move one, and in that pursuit I invented/designed/stuck together this little device called dam thang. Name came from people asking why I hadn't invented the dam thang 30 years before.




        This one is on a 122 cylinder. Install is quick and simple, place, strap and ratchet tight. Works a whole lot better than a cylinder cart too.




        As time went on some ungrateful people complained it needed a handle on the valve end. OK. Grab a cap, quick cut across the top with the plasma cutter or zip disk, 3 pieces of 1/8 pipe to complete the hinge, pin the hinge and finish cutting the cap. Weld on 4 chain links with bolts in place, and it clamps on the cylinder threads real tight. Quick & dirty handle welded on and some rattle can.

        Before you build them I should warn that both devices evaporate faster than SnapOn tools from an unlocked box. Both pieces can be chained and padlocked, but in a welding shop generally all you'll find is a cut chain if you're lucky. Probably not OSHA approved, which explains why it works.

          I use a lot of oxy/fuel. I do not recommend the small cylinders I keep 6 338cf oxygen and 3 of the big acetelene 3 argon, 2 98/2 , 1 75/25, 2 helium, and 2 trimix.

              Nice to see someone who understands the power of plastic and additional stability of the 5 spoked divorced transfer case support system over the traditional metal 4 spoke base.

                Yea we have about three junk chairs made into welding stools like that.
                5 spoke rules. 4 spoke will dump yer butt out on the floor!!

                  I keep a 40 cf tank of c25 as a backup. Although I'm a hobbyist, I've got to where I use a 150cf tank of c25 and argon, but I understand the folks who have a small welder for once in a while repairs don't need a big tank.
