3.13.2 Frequency during pulsed welding
Set the following conditions when pulsed welding (DC pulsed or AC pulsed) has been selected for
the welding mode.
- Pulse frequency (0.1 to 500 Hz)
- Pulse width ratio (5 to 95%)
The pulse width ratio is the ratio of the peak current duration to one period expressed as a
percentage, and it is defined by the following expression.
Pulse width ratio ＝
