Small Argon Tank Pre-Filled for Permanent Jewelry Welders 20scf

Argon is an essential part of the welding process in permanent jewelry, especially when using a pulse arc welder. It creates a stable, inert environment around the weld point, which helps you achieve clean, precise connections on small chains and jump rings.

During welding, temperatures can exceed 7000 degrees, causing the metal to briefly become molten so the weld can form. Argon acts as a shielding gas in this moment, protecting the weld area from elements in the air like oxygen, nitrogen, and hydrogen that can interfere with the finish. Without that protection, you are more likely to see issues like porosity or excess spatter.

A steady flow of argon also supports arc stability, which helps improve control, weld penetration, and the overall finish on gold, gold filled, and silver pieces. This becomes especially important in permanent jewelry where the weld is small but highly visible.

The 20 cubic foot tank size is commonly used because it is compact enough to transport to events while still offering a practical amount of gas for regular use. It fits well into mobile setups and smaller workspaces without taking up unnecessary room.

Pepetools Premium Argon is rated at 99.996 percent purity, also known as Argon 4.6. This means the gas is not mixed with other elements, allowing for a clean and consistent welding environment suited for permanent jewelry applications.

Can I refill this tank?

Yes, this tank can be refilled an unlimited amount of times. A refill cost anywhere from $20 - $35 depending on your region. It is a very cost effective way to utilize argon in your setup.

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. Pepetools premium argon comes in a 20 scf tank, which is the most convenient to carry for craft fairs when used in conjunction with permanent jewelry welding systems. A 20 scf tank will last 4–6 months on average (10,000 welds), depending on use.

Will I Need an Argon Regulator?

We strongly recommend purchasing this regulator to ensure a perfect match to the Pepetools argon gas.

"AGR Inline" regulator will not work with these tanks

What is The Recommended Argon Pressure?

Most pulse arc welding systems work best at around 7 PSI. The pressure can be adjusted depending on the workpiece and how far the electrode protrudes from the welding stylus. The farther out the electrode, the more argon pressure will be required in order to get proper coverage.
