Answer
The correct option is 4.
- 4. 98% Argon 2% Oxygen This mixture is commonly used for MIG welding nickel alloys and stainless steels. The small addition of oxygen helps to stabilize the arc, improve wetting, and achieve a better bead profile and penetration compared to pure argon, without causing excessive oxidation or carbide precipitation that higher CO2 content might.
