oxygen and acetalene tanks

Same boat as you Ron... I assume you frequent the Bremerton store vs. Tacoma?

Mark, yes I use Pacific in Bremerton. I just bought two more cyls at the auction; $125 and it included two almost new regulators. We will see if Pacific takes those as I cannot open the valves.

No prob around here with owned tanks and you can even buy them used at auctions or estate sales and big welding shops honor things and refill.

I know why ACY should go out of style but what else can you get the heat from to heat steel hot enough to melt or burn parts off, etc? I didn't think propane could get that hot.

I've cut 3/4" steel with propane. I've used it for many years. You also use less of it than ACY and it's way safer. Scrap yards around here use it for cutting. It's cheaper than ACY.

I lease my tanks. If I lease for 3 yrs I only pay for 2yrs and get 3rd yr free. $49/tank/year. I have a medium Oxy and a medium AR/CO2 because I can't handle to really large tanks.

I deal with Maine Oxy. Left Airgas when they bought out my local supplier, screwed up my acc't, screwed up my lease [took 3yrs to straighten out] and went way up on their prices.

I have used both propane and natural gas a lot for cutting, welding and heating. Both just slower to heat and not as hot. If you need steel white hot acetylene is the only answer. Now that I have a shop where NG is available, thinking along that line. Any body use CNG for field use versus propane? Cylinder is probably a problem.

I was out in the medgas room this afternoon and came across a Linde cylinder in the Oxygen Manifold with a 6-17 hydro date... that would be June 1917 making it more than 100 years old!!!

I remember hydrotesting tanks back in the md 80's and often found old Oxygen cylinders from the 1920's. Run an inspection light down in the tanks and they were like mirrors inside still. Weighed 20# more than today's tanks too. I bet the tank you saw has a crap load of test dates on it.

Yep... every 5 years.

If only these tanks could talk... WWI, WWII etc... not often I come across something medical with 100 years of service.

I bought my large (Around 5' tall) tanks at a farm auction around a decade back. I hauled them to a local welding shop who explained that they were out of inspection, so I paid to have them sent out and sand blasted, painted, new valves and hydro inspected for 10 years. I took them home and scuffed them down and sprayed them plum crazy base/clear with red stencil lettering saying OXYGEN (2 of them) and Acetylene (1 tank). I've had to refill only 1 of the 2 oxygen tanks since then and the goober at the shop tried to tell me I owed rent, and that he would exchange the tank... I about lost my ****. I paid around $600 for the whole process back in the beginning after the tank serial numbers were run to verify that the tanks are not on the national list of ownership. I originally dealt with the (now retired) father, and the son had no clue of the history of this transaction. I argued until he called his dad and his dad explained that he remembered me and that they are MY tanks... Now I have fear of taking my tanks in since it will potentially be a battle to make it understood that I own and paid for these tanks to be put back into service. Rent... I am not paying no stinking rent!

It is a real problem especially as the Mom and Pop welding supplies fade away.

I cascade my little Oxygen Tanks from the large one and avoid a lot of the non-sense.

Use very little gas these days and I can see where I would need a Hydro each fill.

I agree... I don't use gas so much being that I bought an ESAB PowerCut 650 plasma unit a short time after I got the tanks. I really only use gas to heat things for bending steel or seized fasteners. Plasma spoils the heck out of ya! We live in great times!

Some of the old equipment I work on would be real hard or maybe result in damage without applying heat at the right spot to free things up...
