The Welding Thread

They don't stamp the neck of the bottles anymore?

I called Praxair and they are much more expensive than the other place I called. I will call Airgas and give them a shot too.

Airgas most likely won't sell you anything above an 80cf cylinder, although sometimes managers can make exceptions. Hopefully they can for you, but i'm not sure the price will beat the one you already received.

Unless they have changed things drastically all that stamp indicates is the test date of the bottle. It has nothing to do with the leasing of it. Our local suppliers started to put bar code stickers on your bottle so it ties you too it. Red2.4srt can probably clarify but the number indicates the date tested, so in 5 years it needs to be retested, unless it has a + next to it which gives it 10 years. I could be wrong on the duration's but it's something along those lines.

You're exactly right, test dates will show as 11 14+*, the first number being the month and the second being the year. There should be a grouping of 4 letters/numbers arranged in a square between the month and year which designate the testing facility. The + means it can be 10% overfilled and the * would signify a 10 year retest. If it doesn't have a *, it's considered a 5 year retest only.

So this guy is selling two 300 tanks for $100 bucks. If I don't want a 300 but want a 150 or so, I should be able to trade this in, right?

Edit: The guy said it has West Air stamped on the ring.

I dont really see how you can get flash burn form a good pancake. There is a wooden frame/box on the inside that you sand and tailor to fit your face around your eyes,

like this

its all in what you get used to i guess, but i don't think i would be able to get used to that. i have an older auto dimming hood. every now and then i buy a new clear lens cover for it and put a new aaa battery in the holder. i have the friction set so i can just give my head a quick nod downward and it lowers itself into position perfectly so i can start welding without disturbing my position.

i think the mask above is really cool, but i couldn't imagine getting it in place and then attempting to get yourself back in position while trying to tig something.

Never had the pleasure of using a pancake. welding in a shop with people on either side it wasn't really an option unless you were looking for some flashburn.

everyone freaks out about leased bottles. if you can get your hands on one cheap, just take it in to the gas store whose name is on it and have it refilled. i bet i have 8 or 10 bottles of various size, ownership and age. i have NEVER had a problem getting one refilled. even if i have an owner bottle, it always gets traded out with an "airgas" bottle when i take it back to the store. i have never worried about it and no one has ever given me the slightest bother. some old farmer gave me a 240cf cylinder once. it was pretty rusty from sitting around outside for years. the last inspection date i could find was 1927. the earliest was around 1911. i paid the fee for inspection(i think it was around 15 bucks) and it came back with a new stamp saying it was good for 5 more years and a new coat of paint. what i am saying is that i don't think they fail very often.

also, acetylene cylinders are a different animal, but the high pressure cylinders are all the same except for the valve. lets say you get a cylinder with the wrong valve, you can usually just trade it out at the gas store for the one you need.

one more note: i started out with 60 or 80 cf cylinders that came from craigslist or ebay. at any rate they were really cheap i thought they were a little small. every time i took the cylinders back to be filled, they allowed me to trade up one size. they never charged me more money for the cylincer but only for the extra volume of gas. i now have 2 160cf(maybe 120) filled with c25 for the mig and 2 160's filled with argon for the tig.

it is really nice to have a spare bottle laying around so that when you are in the middle of a project, you don't have to stop what you are doing to get a refill.

Well that would be a concern if it had a barcode sticker on it. That how the companies around here track leasing now. if it does.....pull the sticker off. Than there is no way to identify the tank.

My only fear is that I would be buying an already leased tank and as I understand it, then I would be throwing money away. Local prices aren't very good right now either.

cant really input much on hoods, other than to say my pancake will last me life time more than likely.... Not bulky, not hot and cumbersome to wear, I love it. Best of all a welder friend of mine got it for me, as a thanks for helping him fix his truck on our only day off in 2 and a half months.

I called a LWS and priced out a 125cuft cylinder filled with Argon for $248 after tax. After that it is $38 a refill. Sound about right?

Look on CL for estate sales and actions at farms or industrial businesses. I picked up a 125 and a 300 tank for $250 at one. Test date was shot so I had to pay that fee ($10 a bottle here in Omaha). Good way to get into some big tanks for less money.

Cool beans. I will check Praxair or whatever they are called on the way to work. The guy at the small shop I got the price above from was way nicer than the Yelp reviews said. I just told him outright that I am a hobbyist and that I will never be a big customer. He seemed understanding of that.

That seems about right for the sale, $38 is pretty cheap for a 125 Argon around my area, so good deal on that!

We don't even sell anything above an 80cf cylinder and that sells at $199 filled.

No I run an Lincoln 175 squarewave. I like it because it has a decent amount of juice for aluminum. Suck because no AC balance control. It's been a great rig so far for what I do. I also have a Millermatic 135 for mig, nice little unit for small repairs.

I'd like to get into a tig rig with more options but I have a few other pieces of equipment to purchase before I do that.

Those squarewaves are like an old baseball glove, they do exactly what they're meant to do and very very well. I have a few customers who'll never upgrade because they're so used to what they have.

We had a Tech School drop off a Millermatic 150 2 years before I even started there and it was still sitting there after I started. I asked my boss what was the deal with it and he said they didn't pay the bench charge for it, so it sat unclaimed. He said it needed fixed and I could have it if I wanted it, so I snatched it up, had it tested and it only needed a new gun... So I have a perfectly working 230v MIG for around 90.00 bucks?! Still no shop to use it in though.... Fixed my DD Camry very nicely when I found the back end of a Mazda Tribute. LOL
