If you rent the tank, you must pay a yearly fee and the refills or an exchange with a freshly filled tank. But, if you own the tank, you just need to pay for a refill. Below are the most popular welding gasses sold with a full bottle to give you a price estimate.


Divide the cylinder volume by the gas flow rate to calculate how long your welding gas tank will last. For example, an 80 CF gas tank with a flow rate of 10 CFH (cubic feet per hour) will last about 8 hours.


The flow rate you use depends on the welding process, joint width, whether the joint has a root opening, whether you are welding indoors or outdoors, etc. But, the most common flow rate is between 10 CFH and 40 CFH. We wrote about this extensively in our gas tank sizes guide if you want more information and setting your gas flow rate.


Welding gasses are not expensive after making an initial investment in a gas tank. However, getting the right gas cylinder size is critical. If in doubt, get a larger bottle unless you do a lot of welding on the go.


Manufacturing & Metal FabricationArgon is a welding shielding gas that enhances arc stability and prevents atmospheric contamination of welding pools. Argon is essential to gas tungsten arc welding (GTAW). It also prevents oxidation during metal production.


Aerospace & DefenseArgon is vital for welding special alloys and for various welding applications. It is essential for laser and light bulb manufacturing. In heat-treating applications, argon is used to create inert environments free of oxygen and nitrogen.


CK Supply provides argon gas cylinders in a variety of sizes. Not only are different sizes available, but CK Supply can also provide argon as a compressed gas or liquid. Whether you need to shield a large or small weld area, our experts offer the perfect argon cylinder sizes for your industrial operations.


Argon is used as a shielding gas in Sunstone's Orion Welding Systems. During the welding, process metals are exposed to temperatures of upwards of 7000 Degrees. At these temperatures, most metals become liquid, which allows the formation of the weld. Argon is used to protect the molten pool of metal against elements in the Atmosphere including Oxygen, Nitrogen, and Hydrogen. These elements cause reactions with the liquid weld pool, such as porosity and increased weld spatter. Argon also plays an important role in maintaining Arc stability, which leads to increased weld penetration, better filler wire transfer, and better weld appearance.


We recommend using 99.996% pure Argon (Argon 4.6). This is one of the most commonly used welding gasses in the world. Every major gas supply company will carry this. It is the same as welding gas used in a traditional TIG welding Setup. Pure Argon refers to the gas being just Argon, and not mixed with another gas. Other shielding gasses such as CO2 and Argon CO2 mixes, do not work as well as pure argon. Ultra high purity or medical grade Argon is not required.


It depends on a number of different factors, such as frequency of use, pressure setting, and pre/post flow settings. Sunstone's premium argon comes in an 80 scf tank, which is the most common size for use with Sunstone's Orion Welding Systems. A 80 scf tank will last 6-9 months on average, depending on use.


Sunstone's Orion Welding systems work best at around 10 PSI. The pressure can be adjusted depending on the workpiece and how far the electrode protrudes from the welding stylus. The further out the electrode, the more argon pressure will be required in order to get proper coverage.


All of Sunstone's line of Orion Pulse Arc or Micro TIG welding systems use Argon Shielding Gas to provide a better quality weld and a more stable Arc. Though Argon gas is not required when using the Orino Welding Systems, it is highly recommended for consistent high-quality welds.


The Sunstone line of Orion LZR Laser welding systems offers a wide variety of Laser welding systems from Benchtop to fully automated systems. All of these systems come integrated with an Argon nozzle and Computer-controlled Argon Gas valves, used for shielding Laser welds.


Sunstone offers a wide variety of Resistance Welding Systems for fine spot, micro spot welding. These systems are used for a wide range of applications including batteries, medical devices, industrial applications, Stud Welding, Automotive, Mesh & Screen, and many other applications. Argon Gas is used when required for a higher quality weld, or a better weld appearance.

Argon is a versatile industrial gas used in welding applications, such as the welding of specialty alloys, and in the production of light bulbs and lasers. As an inert gas, it can also be used to provide an oxygen- and nitrogen- free environment for heat treating processes.


Used to maintain temperature and consistency of composition, argon prevents oxidation during processing. It also flushes out carbon monoxide and reduces chromium losses during the Argon-Oxygen Decarburization stainless steel refining process.


Liquid phase argon can be delivered to large or small onsite cryogenic vessels. Pre-filled liquid cylinders are also options. For larger scale liquid argon applications, onsite argon production can be cost effective.


Onsite production enables the highest level of integration of argon supply into user processes, while also providing a solution for uninterrupted argon availability. Read more about onsite argon production >>


A - There are two shielding gases commonly used for arc welding aluminum, and these are argon and helium. These gases are used as pure argon, pure helium and various mixtures of both argon and helium.


Excellent welds are often produced using pure argon as a shielding gas. Pure argon is the most popular shielding gas and is often used for both gas metal arc and gas tungsten arc welding of aluminum. Mixtures of argon and helium are probably the next common, and pure helium is generally only used for some specialized GTAW applications.


When considering a shielding gas for welding aluminum, we need to consider the differences between argon and argon helium mixtures. In order to understand the effect of these gases on the welding operation, we can examine the properties of each gas in fig 1.


We can see immediately that the ionization potential and the thermal conductivity of the helium shielding gas is much higher than that of argon. These characteristics have the effect of producing greater heat when welding with additions of helium in the shielding gas.


For GMAW the additions of helium range from around 25% helium up to 75% helium in argon. By adjusting the composition of the shielding gas, we can influence the distribution of heat to the weld. This, in turn, can influence the shape of the weld metal cross section and the speed of welding. The increase in welding speed can be substantial, and as labor costs make up a considerable amount of our overall welding costs, this can relate to a potential for significant savings. The weld metal cross section can also be of some consequence in certain applications. Typical cross sections for argon and helium are shown in fig 2.


Tests have shown that the relatively narrow cross section of the pure argon shielded weld has a higher potential for gas entrapment and, consequently, can contain more porosity. The higher heat and broader penetration pattern of the helium/argon mixtures will generally help to minimize gas entrapment and lower porosity levels in the completed weld.


For a given arc length, the addition of helium to pure argon will increase the arc voltage by 2 or 3 volts. With the GMAW process, the maximum effect of the broader penetration shape is reached at around 75% helium and 25% argon. The broader penetration shape and lower porosity levels from these gas mixtures are particularly useful when welding double-sided groove welds in heavy plate. The ability of the weld bead profile to provide a wider target during back chipping can help to reduce the possibility of incomplete joint penetration that can be associated with this type of welded joint.


When considering the shielding gas for gas tungsten arc welding with alternating current (AC), pure argon is the most popular gas used. Pure argon will provide good arc stability, improved cleaning action, and better arc starting characteristics when AC - GTAW aluminum.


Pure helium or high percentages of helium (He-90%, Ar-10%) shielding gas are used primarily for gas tungsten arc machine welding with direct current electrode negative (DCEN). Often designed as seam welders, the combination of GTAW - DCEN and the high heat input from the gas used can provide fast welding speeds and outstanding penetration. This configuration is sometimes used to produce full penetration butt welds, welded from one side only, onto temporary baking with no vee-groove preparation, just a square edged plate. 041b061a72
