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, you will need one.

We strongly recommend purchasing the 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.
