Argon is a key component in pulse arc welding systems, as it provides a stable, inert environment that allows for precise and efficient welding. When used in conjunction with a pulse arc welding system, argon helps to reduce the amount of heat generated during the welding process, resulting in a stronger and more durable finished product. The 20cf size tank of argon is also highly convenient, as it is easy to transport and store. This makes it an ideal choice for those who need to perform welding on the go or in a limited space. Overall, using argon with a pulse arc welding system is an excellent choice for those looking to create high-quality permanent jewelry, such as small gold, gold-fill, or silver chains. Its ability to create a stable and consistent welding environment ensures that the finished product is of the highest quality, ensuring that your jewelry will stand the test of time. Argon is used as a shielding gas in Pulse Arc Welding when used with permanent jewelry 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 finish on gold and silver wire for permanent jewelry bracelets. Our 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 18 lbs
• Tank Dimensions 14" Height x 5" Diameter

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. Our premium argon comes in an 20cf tank, which is the most convenient to carry for craft fairs when used in conjunction with the Permanent Jewelry Welding Systems. A 20cf (cubic feet) tank will last 4-6 months on average (10,000 welds), 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 regulator. We strongly recommend purchasing the regulator to ensure a perfect match to the 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 further out the electrode, the more argon pressure will be required in order to get proper coverage
