Select the appropriate shielding gas flow rate for your application to ensure stable gas coverage.
A flow rate that is too high can cause turbulence that draws ambient air into the weld pool. A flow rate that is too low, on the other hand, is often not sufficient to reliably protect the arc and the weld pool. In both cases, pores, oxidation or seam defects can occur.
Under unfavorable conditions - such as draughts, forced positions or sensitive materials - this can also lead to bonding defects or cracking in the joint.
