Local welder supply shops in my area want nearly $500 for a full 80CF cylinder. This “full” 125CF cylinder was just short of $400 shipped to my door. Pretty hard to beat.The cylinder is DOT stamped, so I don’t have much concern about getting it refilled or exchanged when it runs out. And if I’m reading it right, I believe it says the original hydrostatic test was in 08/2024, so this is literally a brand new cylinder.The cap came off with zero effort after I broke it free.Now a few gripes.I’ve seen other reviews reporting pressures north of 2000psi. I put my regulator on the cylinder as soon as I got it out of the box, and it clocked in around 1650psi. If ChatGPT’s calculations are correct, that’s only about 91CF of gas. I wouldn’t call that “full,” but in the end it’s still a better deal than the local shops 80CF cylinder.I ordered this Tuesday, and it arrived today, Thursday. Quick shipping! The original expected delivery date was Saturday, which I was hoping for so that I could be home to sign for it. Instead, I had to deal with my MIL coming to my house while my wife and I were at work to sign for it, and handle a heavy tank of gas.. a minor annoyance, when quick shipping is usually a great thing.I’ve seen the pictures of other reviews where the packaging looked great, and the tank was in perfect condition. My cylinder arrived with the only padding in the box being an expanding foam bag at the head of the bottle. The gas label also got kind of torn up. Doesn’t affect the product at all.. I was just kind of expecting the same packaging that I’ve seen in other reviews on here.So even after my whining about stuff that’s not really a big deal, you can’t beat this. If you want to own your own DOT-stamped 125CF cylinder of 75/25, there’s no reason to look any further than this listing right here.Don’t bother with that cheaper listing where you’re most likely going to get a useless ISO-stamped tank.

Got an empty tank, not even enough to hiss. tank is new and looks nice, one star for now but will ad to it after contacting seller! Got a hold of seller He said he would reimburse me for having tank filled. I had tank exchanged Local welding shop. and got a fast reimbursement. I am happy now and satisfied with transaction. Stuff happens, and I don’t think that this seller was trying to screw anybody. They have good ratings and I think they are honest people.

I was hesitant to order welding gas online but the price savings and convenience of home delivery was enough to take the chance and I’m glad I did. Today, I received a new tank, full of gas, delivered right to the door of my shop. Life is good.

Arrived early. Came full. New tank. packed well. Great value.

While FedEx did their best (delivered upside down) and box torn, the foam packaging protected the valve head (which had its protective metal cap installed).The tank was indeed charged to around 2500psi.

80 cu ft. Tank. Nice new tank with all markings. Came in about a week early. Packaged well. Installed my Guage to verify it was full. Came with 2100 psi.Would buy again.

Delivered before Amazon estimated time, filled to 2100psi, looks like a brand new tank DOT 3AA stamped with a 2024 Date code. Welds great just like C25 should. Couldn’t ask for more, cost almost half the price of what a local big name gas supply was trying to charge me.
