Compressed gas cylinders shall be secured in an upright position at all times except, if necessary, for short periods of time while cylinders are actually being hoisted or carried.
“You can safely transport gas cylinders in a van or by car, provided you comply with the safety regulations,” explains David Hopper, Head of Safety in Air Liquide UK. “First of all, the cylinders must be secured so that they don't shift if you have to stop in an emergency or there's another sudden manoeuvre.
Never transport gas cylinders inside a car, caravan or camper trailer unless it is in a certified gas cylinder compartment. Cylinders need to be transported securely in an upright position in a ventilated location. So, transport your cylinder in a milk crate, but remove it from the crate for refilling.
- Precautions. The safest and recommended method for transporting cylinders (e.g. gas cylinders and cryogenic receptacles) is by using the transport.
- For non-flammable, non-toxic gas loads: • An open vehicle with sides is preferable. •
- Ventilation is the key to reducing the risk of a fire or explosion. •
The only reason that empty cylinders are to be handled and stored using the same safety measures as full ones is that there is no such thing as an empty cylinder. Although they are less dangerous than full cylinders, people could still die if something goes badly wrong.
The car must be well ventilated to prevent oxygen and heat from collecting inside; leave a window open at least an inch or two. Never transport oxygen in the trunk of a car or bed of a truck. In a rear-end collision, an oxygen cylinder can explode, injuring people inside and even outside the vehicle.
Argon gas is colorless, odorless and non-flammable. It is non-toxic. The primary health hazard is asphyxiation by displacement of oxygen.
Liquid oxygen tanks should never be laid on their sides. Portable cylinders can be laid on their sides, but valves must be protected from collision. Tanks should never be placed in a tightly closed space like a trunk.
NEVER keep a filled propane cylinder inside a hot vehicle. ALWAYS transport a cylinder in a secure, upright position so it will not fall, shift, or roll when you're driving. It is dangerous to travel with a tank on its side, so it's extremely important to keep the propane tank in a vertical position during transport.
Does Oxygen Expire? No. The FDA has directed that expiration dating stamps are not to be applied to pressure cylinders filled with medical oxygen, thus indicating that oxygen (O2) is safe,stable, and does not expire.
In summary, it is possible to stick steel together using a MIG welder with 100% Argon shielding gas. If you need a strong, quality weld, 100% Argon is NOT a good choice for MIG welding steel. These problems are even more pronounced with stainless steel, and using pure Argon to MIG weld stainless never recommended.
Tractor Supply Co. carries a variety of welding gas for the DIY homeowner, hobbyists, farmer, or contractor. Purchase welding gas cylinders, or exchange your empty cylinder for a refill of acetylene, oxygen, or shielding gas in a variety of sizes. Just visit your local Tractor Supply Co.
How Much Does Welding Gas Cost? Depending on the size of the cylinder and what gas you are buying, the cost of the gas may vary greatly, leading up to $350 per cylinder. Argon gas is generally more expensive than others because of the difficulty with which it is collected.
| GAS | Cylinder Style | Weight(LBS) |
|---|
| Full |
| Argon | HC-500 | 195 |
| T | 177 |
| S | 95 |
The last Argon tank test date stamp says 8 – 14. And by now you'll be in the swing of reading these tank test date stamps. You'll see this Argon tank was last tested in August 2014. The plus and a star along side means this test is good till August 2024.
So, if you have the room, and can afford it, go with the larger 125 cf tank. Otherwise, select the 40 or 80 cf tank based on your available space and budget. You should also keep refills in mind. A larger tank is cheaper to fill.
The argon gas should be “Pre-purified Grade” purity and should be delivered in a tank at an initial pressure of at least 2640 psi.
Pricing to fill your acetylene and oxygen tanks will vary based on tank size, with larger tanks being cheaper per cubic foot. Your smallest 10 cubic foot tank will cost around $20, #4 tanks at $80, and #5's upwards of $120. Oxygen is cheaper at around $20 for 240 cubic feet or your larger 300+ cubic feet for $35.
Close the bottle valve, loosen the fitting at the regulator to vent the gas in the line, and read the guage. If the gauge says 1000, that's your "empty", and the gauge is in error. If it says "zero", and returns to 1000 when you (re-tighten the fitting and) open the bottle, you still have lots of gas.
It is then MAG, or Metal Active Gas, welding. This is because neither carbon dioxide nor oxygen is an inert gas. MIG welding utilizes inert shielding gases, such as helium or argon, where as MAG uses active gases instead.
In this manner, can you use a oxygen tank for Argon? The good news for you, is that converting FROM oxygen to an inert gas, is easier than converting TO oxygen, because argon tanks do not absolutely need to be "oxygen clean".
Argon is a member of a special group of gases known as the “rare,” “noble,” or “inert” gases. Argon's freezing point is only a few degrees lower than its normal boiling point, –308.8°F (–199.3°C).
Section 1926.350(a)(9) provides that compressed gas cylinders must be secured in an upright position, regardless of whether they are in use or in storage. The standard only permits compressed gas cylinders to be horizontal for short durations when they are being hoisted or carried.
You'll find them smaller and larger, but most homeowner and hobby welders choose Argon or MIG mixes in gas cylinders with volumes of 40, 80 or 125 cf (cubic feet). The larger of these cylinders provide plenty of welding time while remaining portable and easy to transport.
The only thing about laying down is to make sure the regulators are well protected. Nitrogen bottles can be used in any orientation. No need for a settle time, either (unlike acetylene).
