However, it may result in a rougher weld than Argon or an Argon/CO2 blend. CO2ĬO2 is the cheapest welding gases and provides deep penetration, which is excellent for welding thick steel. I remember when I first tried out MIG welding and found that using pure Argon gave me a much smoother and cleaner weld than other gases. Let’s explore the most commonly used gases: ArgonĪrgon is primarily used in TIG welding and MIG welding aluminum. Welding requires different types of gases, and knowing which to use can be just as important as understanding cylinder sizes. For instance, more experienced welders who can maintain a consistent bead with less stop/start action will typically use less gas compared to someone still perfecting their technique. Remember, these welding times are approximate and depend on your exact flow rate and the efficiency of your welding process. The welding time in the table above is based on a standard consumption of 20 cf per hour. This can be used as a reliable tank chart for your projects. How Much Gas Do I Need as a DIY Welder?īelow is a table listing the most common welding tank sizes and their respective volumes.How Long Does a Welding Tank Gas Bottle Last.Welding Tank Material: Steel vs Aluminum.It also works well when TIG welding carbon steel. Argon is great for welding stainless steel and aluminum. The best gas to use for TIG welding is 100% Argon. Argon makes an excellent shielding gas for MIG welding. The best type of gas to use for MIG welding is 75% Argon 25% CO2. Because of CO2 gas's reactivity, it is the most popular blend for MIG welders.įrequently Asked Questions about Argon Tanks What gas is used for MIG welding? This gas mixture is well suited for MIG welding. It is the best shielding gas to use with your TIG welder.

100% pure argon helps keep your welding arc controllable and stable. This industrial-grade gas is ideal for TIG welding. There are no deposits to put down, and you won't be locked into the same store for gas refills. Skip the costly rental fees with gas tank ownership instead.
