AC amplitude balance
As with AC balance, durations (balance) for positive phase and negative phase are set for AC amplitude
balance. The balance changes in terms of the current amplitude.
Figure 4-5
Increasing the current amplitude in the positive half-wave facilitates the cleaning effect and the
cracking of the oxide layer.
Raising the negative current amplitude increases the penetration.
