I do not believe the gas itself will change the arc brightness much, if any at all, but if you need to change your amperage to weld quicker because of the gas i.e. more amps to weld overhead using Argon (because its heavier than air) then you would need a darker lens. its best to simply match your amps and shade. A shade 12 is fine for most arc unless you go over 300 amps.

MIG stands for metal inert gas. It is a non-standard term for gas metal arc welding (GMAW) and flux cored arc welding (FCAW) according to the American Welding Society (AWS). It is simply Metal Inert Gas.

Argon is used in welding because it is an inert gas, which means it does not react with the molten metal during the welding process. This helps prevent oxidation and other impurities from forming in the weld, resulting in a stronger and more durable bond. Argon also provides a stable arc during welding, making it easier to control the welding process.
Tungsten Inert Gas (orTIG) welding is also referred to as GTAW (Gas Tungsten Arc Welding) and by the term Heliarc® which was the Linde Company's trade name for the TIG process when it was originally introduced.The welding arc is started with a sharply pointed tungsten electrode shielded by inert gas. A separate filler rod is fed manually into the weld puddle in much the same way as is done when gas welding.The process is well suited for aluminum.
For welding 8 mm thickness metals, common methods include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and stick welding (SMAW - Shielded Metal Arc Welding). The choice depends on the type of metal and specific requirements.
Metallic Inert Gas Welding - It is a welding process that involves Electricity and a continuous Wire that is used for as a filler rod for the weld.
