Molten metals have an affinity to Oxygen, Nitrogen and other gasses found in the air we breathe. These gasses combine with the metals destroying their integrity. Argon is an inert gas (dead) and does not do this and is why it is used to shield the molten puddle from these gasses. Argon is cheaper than Helium. It is also heavier and does not float away. Heliarc (GTAW/TIG) was developed during WWll and improvements have been made to the process. Replacing Helium with Argon was one of the results. Helium is still used in some instances when welding Aluminum as it allows the heat from the arc to travel thru it better than Argon does. In some situations mixtures of both are used.
