Tig Welding with Argon CO2 Mix

Most welders have heard of TIG welding, but many don’t know about the advantages of using an argon CO2 mix for their projects. Argon, a common gas found in the atmosphere, and CO2, a gas created by burning organic materials, are both used in this type of welding. When used together, the combination can provide excellent welding results as well as cost savings.

What is TIG Welding?

TIG, or tungsten inert gas welding, is a type of arc welding process that uses a non-consumable tungsten electrode to create an electric arc. In this type of welding, an inert gas is used to protect the weld area from contamination by oxygen and other elements. This gas is usually argon, but other gases can be used as well.

Advantages of Using an Argon CO2 Mix

Using an argon CO2 mix in TIG welding has a number of advantages. First, the CO2 helps to increase the welding speed, allowing for faster and more efficient welds. Second, the CO2 also helps to reduce splatter and spatter adhesion, making post-weld cleaning easier. Third, the argon helps to reduce the amount of ozone created during the welding process, making it a safer option for welders and those in the vicinity. Finally, the combination of argon and CO2 results in lower welding costs as well as improved weld quality.

How to Set Up an Argon CO2 Mix

When setting up an argon CO2 mix for TIG welding, it is important to ensure that the gas is the correct type and that it is correctly mixed. The most common mix used is 90% argon and 10% CO2, but this can be adjusted depending on the type of work being done. The flow rate of the gas should also be set correctly to ensure that the welds are of the highest quality.

Using an Argon CO2 Mix for TIG Welding

Once the gas mix has been setup correctly, the welder is ready to begin welding. The process is relatively simple, but there are a few tips to keep in mind. First, it is important to ensure that the tungsten electrode is clean and free from oxidation. Second, it is important to keep the arc length consistent and to maintain a consistent travel speed for the best results. Finally, when welding, it is important to keep the arc focused on the workpiece to ensure the highest quality welds.


TIG welding with an argon CO2 mix can provide welders with a number of advantages, including increased welding speed, reduced spatter and adhesion, reduced ozone levels, and improved weld quality. To ensure the best results, it is important to set up the gas mix correctly and to maintain a consistent welding technique. With the right setup and technique, TIG welding with an argon CO2 mix can be a great way to get the job done.
