Description

The "40 CF Welding Cylinder Tank Full 100% Argon Welding Gas Cylinder Tank CGA 580 - FULL" is a specific type of gas cylinder used in welding applications. Let's break down the description: 40 CF Welding Cylinder Tank: This indicates that it is a welding cylinder tank with a capacity of 40 cubic feet (CF). 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. Argon is commonly used as a shielding gas in various welding processes, including TIG (Tungsten Inert Gas) welding. It is used to protect the weld area from atmospheric contamination, ensuring clean and high-quality welds. Welding Gas Cylinder Tank CGA 580: The CGA 580 designation refers to the valve connection type on the cylinder. 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.

  • 40 cu/ft 100% Argon Welding Gas Cylinder Tank CGA 580 - FULL
Needed a small bottle of Argon for some TIG welding, this was perfect for my needs. A great price and a quality bottle.

  • On time, in date and securely packaged
Bottle arrived on time, very securely packaged to protect the 'naked' valve and properly filled. Cert date is 3 months ago meeting listing claims. I haven't had a chance to taste the gas yet but expect it will be correct esp. seeing how it is a single gas and not a mix.

  • I needed Argon gas for Al/SS welding
Nothing to complain about here. Sherwood valve, new tank and already full (2200 psi) on delivery. Delivery being the key rub.. FedEx kinda bobbled the delivery. Somehow got lost/stuck at one of FedEx depot's for nearly TEN days! Not the seller's bad, but sheesh! really? Glad I was not in a hurry

  • Just received my tank today Just received my tank today
My tank was delivered on time. It was a little less than 3/4 full, the date on the tank says 2024 / 5. I hope that's the date it was certified. Update... after contacting the seller about the tank not being full they immediately refunded the money to cover the cost of gas that was short. I raised my rating fron 4 stars to 5 stars due to their fast response in making sure that I was 100% satisfied. I highly recommend this company. ... show more
