80 cu/ft 75% Argon 25% CO2 Welding Gas Cylinder Tank CGA 580 - FULL

Brand new tank filled great price.

Tank is made from new materials and is full of gas. Appears to be a quality product and would recommend for purchase. Great for tig welding and small jobs.

Clean tank filled and ready for use. Showed up sooner than expected and works as intended.

I received a perfect new tank, and looks to be top quality. Not much really to talk about... it's a gas cylinder, and it appears to be top spec and well within the <2 year age specified by seller. Nothing bad to see here.Reading some other reviews concerned me at first, because until researching for myself, I may have also thought there was a problem. I have never bought one of these before, and I did a bit of research (it didn't take much time). The stamped cylinder markings prominently states "DOT 3AA 2015", which to the unaware would look like it is a date, making this 5 years old. As it turns out, the 2015 has nothing to do with a date. DOT 3AA 2015 is the Dept of Transportation specification code. 3AA means high pressure steel and 2015 PSI is the service pressure specification of the tank (see the table I uploaded).The manufacture date is a bit more cryptic in the codes stamped on the tank (see photos). So, I believe you can disregard the negative reviews saying it was 5 years old, etc. I think that is not the case, but more likely a misunderstanding of the stamp marks on the tank. In my case, the tank was manufactured and certified about 14 months ago... well within the <2 years advertised.I replied to some recent negative reviewers with some code decrypting on my tank, which you can find if you look for some of my comments to negative reviewers. I've included some of the info on the pictures I uploaded. Hopefully it helps in your decision making.

Came exactly as described. Full bottle. DOT markings. Just over 9 years left until hydro is due. Valve is new. Zero complaints.It arrived 6 days prior to posted delivery date.

Came filled to 2000 PSI, but the tank is marked “022” and a “+” so 2420 PSI (2200 + 10%) seems more appropriate. Oh well, still a much better deal than buying local where I would have paid over $600 for the same item.The test date appears to be 03/22, and there’s a star stamped in so it shouldn’t need a retest until 2032. Good.The cap threads fit poorly, very loose making the cap hard to put on (threads jam). Appears to be the cap threads rather than the tank. It does go on but it’s kind if a struggle.Delivery was good, a burly Amazon delivery driver brought it right to my door. I did have to sign for it. It was packed in a skinny cardboard box with lots of packing around the valve cap and arrived in good shape.The contents (argon/CO2) are correct, far as I can tell - it produces clean welds, no porosity.Overall good, I recommend.

I hate dealing with my local ARC gas supply. This eliminates the assH-les. Arrived well packed and had a 2024 date code.

Very satisfied The bottle was DOT stamped as promised and Full
