Schedule setting screen (2/2)
(j) SCH
The currently selected condition No. is displayed.
(k) Weld2 welding pulse modulation ON/OFF
Select whether to apply the pulse modulation to the second welding current.
[Initial value: OFF]
(l) Weld2 welding frequency [Hz]
Set the modulation frequency of the second 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]]
(m) Weld2 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 [%]]
(n) Weld2 up/down pulse modulation ON/OFF
Select whether to apply pulse modulation to the welding current in the UPS
(up-slope) and DWS (down-slope) section of the second welding.
[Initial value: OFF]
(o) Weld2 base current [A]
In the effective section of pulse modulation, modulation is performed by using the set
value as the minimum current value. When the base current value is higher than the
welding current value, modulation is not performed. The setting range is 15 ~ 300
[A] (in unit of 1 [A]).
[Initial value: 15 [A]]
(p) Screen return switch
The Welding condition setting screen (1/2) is displayed.
(q) Screen feed switch
