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.

  • Arrived fully charged, very happy with the size.
I'm learning tig welding and wanted a small tank, this fits the bill perfectly. With my light use, I expect this to hold enough argon for several months, and I can get it refilled locally.

  • This was fine, but a 125cu/ft tank is a better value & less of a hassle

  • A great purchase 👍
The package arrived 3 days early, properly packaged and completely full. Great first experience with this order. If I ever need an argon/CO2 cylinder, I will order from this same company. 10/10

  • 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

  • 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.
