Argon Tank

Argon Tank - Premium Argon Gas (Not a Refill) If you have ordered a tank with us before and are needing a refill, please scan the QR code on your tank to start the refill process. UPS Ground Shipping to Continental US States Only, No Alaska or Hawaii. Argon 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.Sunstone's Premium argon is 99.996% pure Argon (Argon 4.6). Pure Argon refers to the gas being just Argon, and not mixed with another gas. How Big is the Tank? Weight 44 lbs Tank Dimensions 27" Height x 7" Diameter Tank Size 50 scf About How Long Should My Argon Tank Last? 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 50 scf tank, which is the most common size for use with Sunstone's Orion Welding Systems. A 50 scf tank will last 6-9 months on average, depending on use. Will I Need an Argon Regulator? Yes, if you do not already have a gas regulator please click here to order the AGR 2 regulator. We strongly recommend purchasing the AGR 2 regulator from us to ensure that you will have the proper type of regulator to match the tank we send you. "AGR Inline" regulator will not work with these tanks What is The Recommended Argon Pressure? 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. Argon Tank Return Policy As an addendum to Sunstone's returns policy, kindly note Sunstone is unable to accept returns on any of the company's argon tank products. Argon Safety Data Sheet*Note about Tariffs (Updated May 1, 2025) Sunstone is a home-grown, made-in-USA company. Most of our welders are engineered and built by skilled American workers who take pride crafting high-precision, highly robust welders. During manufacturing, Sunstone uses parts and materials sourced from U.S. companies whenever possible. In some instances, parts and materials may be sourced from outside the U.S. due to availability and cost. Unavoidably, recent tariffs have increased the cost of parts and materials. To offset the increased cost in manufacturing, beginning May 1, 2025 Sunstone is adding a modest surcharge to affected products. The surcharge for this product is 144.42 and has already been added in to the purchase price. We will continue to monitor tariff costs and will happily adjust these down or eliminate them all together if possible.
