Argon is used as a shielding gas. Argon is used to protect the molten 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 improves weld penetration, better filler wire transfer, and better weld appearance. Sunstone's Premium argon is 99.996% pure Argon (Argon 4.6).

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 our deluxe regulator. We strongly recommend purchasing the a regulator from Sunstone to ensure a proper match with a Sunstone tank.

Note: An "AGR Inline" regulator will not work with a Sunstone argon tank.

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.

What You Need to Know about Shipping

UPS views any compressed gas tank as a hazardous item and adds a fee to the normal shipping cost. Sunstone will ship your argon tank in a special box certified for compress gas tanks. Further, the valve at the top of the tank is protected by a steel cover. Finally, we pad the top and the bottom of every tanks with custom foam inserts. Per UPS requirements, we clearly mark the box for easy identification.
