hi everyone, a year ago I got into welding and has been hooked ever since. Got myself a Lincoln Electric welder for home use with flux core wire but it just burns way hotter and splatters way more than MIG. Now i'm thinking of getting an argon/co2 mix shield gas cylinder to do some hobby project.I know with this is an inert gas so it doesn't burn or explode but it is at the end of the day in a compressed container. I was planning to drive over to my local welding supply shop when my wife stopped me saying she's not comfortable because those cylinder tanks look like missiles which it is if the tank disintegrates.I have a welding cart so the tank will be strapped and the cap will always be on when i'm not using it. Just the typical common sense things with any compressed content.Now I'm thinking of getting a much smaller 20 CF cylinder because it looks less "intimidating" .Any thoughts or suggestions?
Reply:Get over it. A 20 cylinder is not good for much, you want as big as you can get. Biggest danger going to getting a cylinder is getting killed in traffic on the way to the store. You face hundreds of thousands of # of oncoming steel at hi speed per hour in a car, a bottle is pretty low on the risk to life scale.Last edited by Sberry; 1 Day Ago at 11:35 AM.www.urkafarms.com
Reply:Look at it this way, half of the times the cylinder will be nearly empty of pressure. Therefore you are only at some minimally higher risk on the drive home with a full tank. Statistically, your risk of a car accident is the same no matter what or who you have in the vehicle.

Reply:I think odds are 5000 to 1 of being killed in a car. Wonder what it is for bottle accidents?www.urkafarms.com
Reply:They can be dangerous for sure, the big thing being having the valve at the top damaged. As long as you keep your bottle cap on until it is secured in place and anytime you are moving it around, you wont have any problems. All a smaller tank will do is tick you off because youre going to have to fill it more often. The smaller tanks are still filled to the same pressures as the larger tanks.
Reply:I have work with bottles gas since the 1960's have not had any problems. Following the rules and they are safe. I would buy steel bottles only.Dave

Reply:If you buy gas in the smaller cylinders, the economics on a cost per cubic foot basis become bad, really quickly. Do yourself a favor, and find a local welding supply shop (aka LWS for short) that will do residential deliveries. Here in Thomaston CT I use Maine Oxy out of Naugatuck. For a nominal fee (like $24, I don't recall the exact amount), they will deliver any size tank to my home, along with anything else they stock in the store. And its not $24 per tank, its $24 per delivery regardless of how much gets delivered. I never go into the store anymore. AND the money I am saving on the gas pays for the lease charge on the larger tank as well as the delivery charge. If you can't find an LWS who will deliver for a reasonable fee, I wouldn't sweat it. Most places will not sell you a tank larger than 80 cubic feet, which in itself is pretty small. Make sure you strap it in when transporting and don't worry about it. Your risk of an incident with the gas cylinder is infinitesimal compared to your risk of dying in a car crash, with or without the tank in the trunk. You are worrying about something that is very safe.Last edited by Louie1961; 1 Day Ago at 01:17 PM.Miller Multimatic 255
Reply:That cylinder is safer than any electric/battery appliance/device you own. Try to get yourself at least a 125 cu ft tank if possible. Gas is way cheaper and the aggravation of being low on gas so often and the added cost make the gas cost you like $100 for the same amount you could get one time in a 125 cu ft for $30And the regulator only comes off when you are moving or transporting the loose bottle around. Turn the valve off when you unplug/turn off the machine. Lol.Last edited by danielplace; 1 Day Ago at 01:06 PM.
Reply:Thanks everyone. Shes not concerned about the transportation part but more having a compressed cylinder sitting in the garage all the time. But just from what all of you are saying, just follow some common sense tips and it is safe! My local welding shop has 80cf bottle which is considered best value.Last edited by PassionateWelding; 1 Day Ago at 01:16 PM.
Reply:Biggest risk is likely on the road.... the smaller the cylinder, the more times you'll be on the road. Maybe build yourself a ventilated cabinet to store it in and she'll forget about it.The harder you fall, the higher you bounce...250 amp Miller DialArc AC/DC StickF-225 amp Forney AC Stick230 amp Sears AC StickLincoln 180C MIGVictor Medalist 350 O/ACut 50 PlasmaLes

Reply:Shielding gas is expensive! The bigger the tank, the lower the CF cost of gas is. In my case, I lease the 330 CF size tanks. I doubt you will be able to buy big tanks, Timothy Mc Veigh & others.Some vendors will deliver gas & near all industrial gas consumers get it delivered.Yes, I've heard horror stories. Bromley Ski area had a cart with oxygen & acetylene on one cart. Some knucklehead tipped it over, it landed on a machine & broke the oxygen valve off. The tank jetted through the closed overhead door. I'd say strap it in, don't carry it in an enclosed vehicle if you can help it. If your welder is stationary, chain the tank to the wall. If you have a welder on a cart, be sure the cart is very stable & chain the tank securely. Cap on when wrestling the tank.An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.

Reply:Compressed gas cylinders have an excellent safety history, do you ? Using the safe handling procedures, which can be learned easily, death and injuries are incredibly rare. Are you the kind of person who will understand the risks, and hazards. Will you remember to follow those rules. If so, you should be safe. If you're a "I got this, hold my beer, how dangerous could some gas be?" type person, your wife might have some concerns. Like guns, they are only as safe as the person handling them. Over the years I've taken many safety courses/seminars for safety in welding/cutting, its a good way to stay current and refresh your knowledge. You can usually take an adult education course at a community college/technical school, for a small fee . If you do, you can tell your wife that you've been trained, and are authorized to handle High pressure tanks safely. That can often go a long way when trying to convince someone that your able to do something safely (Wife , Boss, Partner/associate)If you search through the OSHA database, you can see that the worst accidents involve reactive gases like oxygen, propane, chlorine, in which people are burned. Another portion of injuries are people having tanks dropped onto them, or knocking them off ladders.https://www.osha.gov/pls/imis/Accide...r=2023&InspNr=Here's sampling of some listed on the OSHA database :At approximately 10:40 a.m. on June 28, 2017, an employee was processing scrap m etal. The employee grabbed a Stihl T5700 Concrete saw with a 10-13 inch blade t o cut through an oxygen cylinder that is used for home oxygen. The cylinder sti ll had the valve attached and was pressurized. The employee cut into the cylind er with the saw resulting in an explosion and a small flash fire. The employee w as thrown back a couple feet and his clothing caught fire. The employee was wea ring PPE, safety glasses, steel toed shoes, gloves, hearing protection. The saf ety glasses broke as a result of the explosion. The employee received second and third degree burns to his arms, chest, torso, and face. The employee also rece ived a fractured sternum and punctured lung. There were also burns to the emplo yee's eyes. The employee was hospitalized and treated for his injuries.

Reply:50+ years. I try to be safe, but have been known to fail to take precautions. I've never had a mishap. There are many gasses used by welders. I am limited, but I use acetylene, propane, oxygen, carbon dioxide, argon, argon/carbon dioxide mix, and helium. Dabbled with stainless MIG gas briefly.Hydrocarbon gasses are fuel & accelerant. Oxygen turns burn into something exponentially worse, and you can suffocate in concentrated atmospheres of all the shielding gasses.Most of these tanks contain enough pressure to become a rocket, but they are very robust tanks. Don't EVER move one without the cap on. Protect them while connected to a regulator from tipping over, or objects hitting them. Don't park the MIG in a bay where a runaway car might hit it. A full oxygen cylinder might be 2300 PSI (I'm estimating). With the cap on you could throw it down a stairway in a skyscraper. Cap off, all bets are off.Fuels are all vapor at atmospheric pressure. Slow leaks in confined spaces are the worry. They rarely leak, and if well ventilated, pose no hazard.Last edited by Willie B; 1 Day Ago at 09:11 PM.An optimist is usually wrong, and when the unexpected happens is unprepared.
