Modulation duty ratio = t/T x 100 [%]
(e) Weld1 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) sections of the first welding.
[Initial value: OFF]
Waveform sample when the UPS/DWS pulse modulation is applied.
(f) Weld1 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 1.00 ~ 9.99
[A] (in units of 0.01 [A]) and 10.0 ~ 50.0 [A] (in units of 0.1 [A]). (*1)
[Initial value: 5.00 [A]]
*1 For welding very small workpieces, only FST and UF1 of WELD1 can be set from
1.00 A of the minimum current set value. However, the initial value is 5.00 A.
Remarks
If the value less than the effective digits for the current set value is input, it is rounded
off when the screen is switched from the Welding condition setting screen to the
Monitor screen to establish the set value. For example, when “10.55” A is input, the
effective digits for 10 A or more is 0.1 A, the set value is automatically corrected to
“10.5” A when the screen is switched from the Welding condition setting screen to the
Monitor screen.
(g) Screen return switch
The Welding condition setting screen is displayed.
(h) Screen return switch
The Schedule setting screen (2/2) is displayed.
