Is Argon Gas Dangerous?

Argon is a chemical element, one of the noble gasses, and the third most abundant gas on earth. Generally speaking, this element is not dangerous to use as an inert shielding gas as it is inflammable and nontoxic. Additionally, it is odorless and entirely colorless.

There are some safety concerns, however, as argon comes in compressed tanks, and you should always follow the proper safety guidelines when connecting, storing, and moving these cylinders. This element is 38% denser than air, and, if you usually weld in enclosed work areas, you should take steps to ensure adequate ventilation.

Welding Cylinders Explained

Gas and arc welding requires a supply of compressed gasses to shield the molten weld pool and prevent oxidation, impurities, and the formation of air bubbles.

The gas you need depends on the process. For example, to weld with oxy-fuel, you need acetylene, propane, propylene, and natural gas, to MIG weld, you need CO2, argon, helium, or a blend, and to TIG weld, you need argon.

Gas is contained above atmospheric pressure inside metal cylinders or tanks. A typical tank has an elongated shape and stands upright on a flattened bottom.

The cylinder type depends on its capacity, weight, size, and the gas it contains. We’ll be primarily focusing on the argon (Ar) cylinder category.

Fitted to the top of a cylinder is a valve and a stop connection (typically a CGA-580) to ensure compatibility with regulators and hoses.

Different Types of Welding that Require an Argon Welding Tank

Argon is commonly used in MIG- or TIG-welding processes to create an inert shield that is free from oxygen and nitrogen. This gas is suitable for use on non-ferrous metals like copper, aluminum, and magnesium, and it reduces the accumulation of dust and spatter.

Depending on the metal type and thickness, argon can be mixed with hydrogen, CO2, helium, or oxygen to optimize weld quality. Generally, a 75–25 Ar–CO2 mixture is more effective for MIG processes, especially if you weld mild steels. 100% argon is more suitable for TIG welding.

Micro TIG systems require Ar gas to ensure the stable arc needed for a precise and high-quality weld. Bench-top and automated laser welding systems are typically also fitted with argon nozzles and computer-controlled valves to provide a laser with an inert shield.

Since argon is necessary for a detailed and high-quality category of work, resistance systems typically use it for fine or micro spot welding. This liquid state process is used in several applications, including the manufacturing of electric cells, medical devices, and automotive components.

What Type of Argon Gas Will I Be Receiving?

When purchasing from credible suppliers, you can expect to receive Ar 4.6, which has a purity of 99.996%. This purity is also suitable for all TIG processes to prevent the exposure of the molten weld pool to the oxygen, nitrogen, and hydrogen in the atmosphere, which can result in porosity and splatter.

With the MIG process, however, you will need to evaluate your welding objectives as pure argon may not be ideal. There are several Ar blends, each with different levels of penetration, bead profiles, and travel speeds. CO2 and helium are commonly mixed with Ar inert shield gas for MIG welding.

How Long Do Argon Tanks Last?

In terms of lifespan, a tank can last from 10 to 25 years, depending on how well it is manufactured and maintained.

As for the usage of a container’s Ar content, many different factors play a role, including the following:

– Size of the tank

– Am customer’s usage frequency

– Pressure setting

– Pre- and post-flow settings

If you are continually using between 15 and 20 cubic feet of gas per minute, a cylinder with a capacity of 40 cubic feet will last you around 2 to 2.5 hours. In the real world, however, you can expect a small cylinder to last you a few months.

Will My Argon Welding Tank Require a Pressure Regulator?

A pressure regulator maintains the flow of shielding gas to the puddle. To effectively control the arc, the outflux of gas must be smooth and controlled. However, if you connect the cylinder directly to the hose, you will empty its content in a matter of seconds, and the results will be undesirable.

A regulator is fitted with a knob that limits and controls the rate of flow. A regulator measures flow either as liters per minute or cubic feet per hour.

As a general rule, the thicker the metal you weld, the more inert shield gas you need. The type of metal you weld is also a determining factor when it comes to gas flow.

Consequently, your Ar tank is likely to require a pressure regulator, which you will have to purchase separately.

Size and Portability of Your Welding Tank

Argon Cylinder Sizes and Welding Time Chart Explained

If you are using Ar at a continuous rate of 15 to 20 cubic feet per second, the different cylinder sizes will be used up within the following times:

20 cu ft: 1–1.5 hours

40 cu ft: 2–2.5 hours

60 cu ft: 3–4 hours

80 cu ft: 4–5 hours

125 cu ft: 6.5–8 hours

150 cu ft: 7.5–10 hours

250 cu ft: 12.5–16.5 hours

330 cu ft: 16.5–22 hours

In reality, you will never weld for hours on end, and a cylinder with a capacity of 20 cubic feet can last you for weeks or even months if you are conservative with your usage. If you need gas for large industrial or commercial jobs, you will need a cylinder with a capacity of at least 125 cubic feet.

Best Way to Transport Your Tank Safely

If you have a small tank with a capacity of 20 cubic feet, it may save you a lot of time to carry it yourself over short distances. However, if you have two or three tanks with a capacity of 150 or 250 cubic feet, a hand truck can save you a lot of time and effort. They work as an effective delivery system to move your Ar container or containers around your work site.

Some cylinder carts can accommodate two or more tanks, so you can keep them strapped into the cart for use without taking them down. If you work at different sites and have to haul your MIG or TIG welder around, it may be more sensible to purchase smaller tanks.

Argon Gas Storage Recommendations

Where Is It Safe to Store?

You should always follow safety protocols when storing your welding gas tanks. A cylinder should be stored upright in a cool place where it will not come into direct sunlight. The bottle storage area should also be completely dry to prevent corrosion.

Don’t store your tanks inside an enclosed vehicle, even for short periods. If you must, make sure that there is sufficient ventilation to prevent the build-up of heat and pressure.

If your cylinder is in storage for a long time, remove the regulator, close the valve, and put on the safety cap. You should also inspect the exterior regularly for signs of rust and other signs of deterioration and check the valves for signs of damage.

The cylinders should be fastened with straps or secured against a wall to prevent them from falling over. If you move the tanks to a storage area, wear gloves, safety glasses, and shoes with steel toe caps to prevent personal injuries.

How Is It Transported Best for Safety?

Moving cylinders can be a challenging endeavor as they are heavy, volatile, and awkward to handle. If you have to move them over short distances, a hand truck or cart may be your best option. On the other hand, if you have to transport them with a vehicle, you will have to follow the same safety protocols that apply to storage.

Ventilation is crucial to prevent high temperatures. You should also take steps to ensure that the cylinders are securely fastened to fixed structures in the vehicle so that they don’t fall over and sustain damage. Before transportation, close the tank valves, and put on their safety caps.

Owning vs. Renting Your Argon Cylinder Tank

If you don’t have gas available for your metal construction needs, one of your first decisions is whether you should purchase or rent your tanks. Let’s take a look at the benefits and drawbacks of owning a container.

Pros of An Argon Cylinder

You can purchase a brand-new cylinder that is hydro-tested and filled. When you use all the gas, simply take the cylinder to your local gas outlet for a refill. There are several other benefits to owning an argon cylinder:

– You have full ownership and control over the tank

– You don’t have to pay a monthly or yearly rental fee

– If something happens to the cylinder, you don’t have to pay damages

– The value of argon cylinders increases over time

– You have some discretion over what you want to do with the cylinder

Cons of An Argon Cylinder

Despite the benefits of owning your tank, many welders prefer to lease or rent their cylinders. This is because there are several drawbacks to bottle ownership, as well as benefits to renting one.

– You don’t have to worry about hydro-testing, DOT, or ISO compliance

– There are no upfront costs

– Refills are generally quicker as the owners will change your tank

– If you are not using a cylinder for the foreseeable future, you can return it instead of finding storage space

– Less time shopping for or maintaining Ar containers

Whether you should rent or buy a tank depends on your unique situation, and you should consider these pros and cons carefully.

A Man Using Welder

There are numerous places where you could go shopping for one of these machines online – eBay, industrial sites, etc. Additionally, there are always people who post their offers on tech sites, which might or might not be related to whatever you are looking for. However, these welding tanks aren’t toys, food, or something you should take too lightly – buying one will always be a costly investment, not to mention the risk of purchasing faulty tank.

However, the safest place you can order this tool and any accessories online is Amazon. Apart from being the most popular and reliable online service, this online market has a strict set of rules that apply to users on both ends: vendors and buyers. They also provide free shipping or delivery to some areas.

Amazon Logo

One of the best things about Amazon is that you are entitled to use their return/refund policy. People ship their items overseas all the time, and even if your vendor is a local gas supplier, an accident can occur at any time. Your package might be delivered to you in a damaged condition – that’s where return policies come into play.

Hopefully, you have a better understanding of argon as an inert shield gas for TIG and MIG welding processes, as well as the various options for storing and transporting now.

There are several aspects to keep in mind when it comes to this element. The first is your supply in the form of cylinders. These tanks are available in many different sizes, and they can contain mixtures with CO2 and helium.

Finding a cylinder with a capacity that meets your portability and usage requirements will save you a lot of money and time in the long run. You will also need a regulator to control the flow of gas to shield your molten weld puddles.

Additionally, you will need a cart or hand truck for moving your tanks between your vehicle and work sites or for optimal positioning. Before buying a cart, consider its load capacity, wheel size, and fittings for securing the argon tank to the cart.
