WebFeb 2, 2024 · So not surprisingly, shielding gas flow can also affect the weld quality. A good starting point is 20 to 25 CFH. Keep an eye on the weld surface and the area around weld toes. If you notice porosity, increase the flow. Using a tri-mix shielding gas (i.e., 10% Ar + 85-90% He + 2-5% CO 2) increases the amount of helium when you increase the gas ...
