Cubic feet is a unit of measurement for the volume of gas that the cylinder can hold. Full 100% Argon: The gas contained in this cylinder is 100% pure Argon.

CGA (Compressed Gas Association) 580 is a standard connection type used for Argon and other inert gases. This valve is designed to fit regulators and other equipment that are compatible with CGA 580 connections. FULL: This indicates that the cylinder is full and ready for use. Gas cylinders are typically filled with the specified gas and pressure before being sold or used.

## Questions & Answers

**Q: Idealy how long shoyld this bottle last for a tig set up. Ive used my welder 4 times at maybe 30 min each time and the bottle is empty..?.**
A: With TIG, it won't last long at all. The math is pretty easy to do. If you're using 20cf/hr, this bottle will last four hours. When I was learning how to tig, I went through a 200cf bottle every five days. This bottle is only 20% of that size.

**Q: Is this a full cylinder?**
A: If is is listed as "40 cu/ft 100% Argon Welding Tank CGA 580 - FULL" you should get a full tank. Empty tanks on Amazon sell for $80-100 less than full ones but my local gas guy won't fill a tank they did not provide. It was still much cheaper for me to buy it this way since I use very little Argon. Mine was delivered at 2000psi at room temperature.

**Q: Argon purity? please don’t say it’s 100%; it isn’t. it will have some ppm amount of co2, h2o, o2, n2, etc. i’m a chemist, so please, where’s the coa?**
A: Whatever as long as the content is argon gas and suitable for you application.

**Q: How long does it take for the welding time?**
A: Depends how much you weld, and what you weld.
