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.
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.
