Frequency in AC: With higher frequencies the arc is more intense, and the weld bead
has a better application and the sound of the process is higher. It is recommended to work
at low AC frequencies.
11.
AC Balance: is the percentage of negative AC wave in the wave period. The higher it
is, the smoother but shallower is the weld bead and the tungsten deteriorates more
quickly. It is recommended to work the AC balance in low.
