4. Explanation of Screens
4-27
(10) Schedule Setting Screen
This screen is mainly used to set the pulse modulation of welding current. The welding current is
determined by the data set in the welding condition settings and the data set on this screen. There
are two types setting screens, namely, Schedule setting screen (1/2) to set the first welding and
Schedule setting screen (2/2) to set the second welding.
Schedule setting screen (1/2)
(a) SCH
The currently selected condition No. is displayed.
(b) Weld1 welding pulse modulation ON/OFF
Select whether to apply the pulse modulation to the first welding current.
[Initial value: OFF]
Waveform sample at pulse modulation OFF
Waveform sample at pulse modulation ON
(c) Weld1 welding frequency [Hz]
Set the modulation frequency of the first welding pulse.
The setting range is 1 ~ 3000 [Hz].
This setting is also applied to the pulse modulation frequency of up-slope and
down-slope.
[Initial value: 1 [Hz]]
(d) Weld1 welding duty ratio [%]
Set the duty ratio of welding pulse. The setting range is 10 ~ 90 [%].
This setting is also applied to the pulse modulation of up-slope and down-slope.
[Initial value: 50 [%]]
