Argon helps keep the weld environment completely inert, and it helps to form a very stable, controllable arc. So, in short, TIG welding needs pure argon to protect the tungsten electrode, and MIG welding works best on a 75%/25% argon/carbon dioxide mix to get good weld penetration and flow.

TIG welding
Can I TIG weld aluminum with DC?
DC is used for TIG welding Mild Steel/StainlessSteel/StainlessResistance to corrosion and staining, low maintenance, and familiar luster make stainless steel an ideal material for many applications where both the strength of steel and corrosion resistance are required. Moreover, stainless steel can be rolled into sheets, plates, bars, wire, and tubing.https://en.wikipedia.org › wiki › Stainless_steelStainless steel - Wikipedia material and AC would be used for welding Aluminium. The TIG welding process has three options of welding current based upon the type of connection. Each method of connection has both advantages and disadvantages.

Can a DC welding machine weld aluminum?
You're going to send a lot of heat into the weld joint when you're running DC power. In addition, some welders note that they have had better success TIG welding aluminum on DC by using thicker, much thicker, electrodes for their welds.
What can be DC TIG welded?
What metals can I weld with an AC/DC TIG welder? An AC/DC TIG welder can be used to create high-quality welds with aluminum, stainless steel, carbon steel, copper, titanium, nickel alloy, and more. Being able to choose between alternating and direct current gives you convenience and flexibility in one machine.
Can you TIG aluminum without gas?
Simply put, NO, you can't Tig weld without Gas! Gas is required to protect both the Tungsten Electrode and the weld pool from Oxygen. Most Tig Welder torches are also cooled by the gas, so not using gas would risk burning out the Torch.
Can you weld aluminum without gas?
Yes. Arc welding of aluminum can be done in a vacuum chamber without shielding gas because the purpose of the gas is to displace atmospheric gases which contaminate the weld and do not promote a stable Arc.
