(c) Time
Each operating time at welding can be set individually.
For the details of each item, refer to the following table.

0 ms
*3 Setting to 0 ms becomes the auto mode or fine weld mode. Setting to 1 to 999
ms becomes the normal mode. (Refer to 5. (6)-2 Operations.)
*4 Settable time cannot be over 4000 [ms] as shown below:
[WELD1 section set time] + [COL set time] + [WELD2 section set time]
≤
4000 [ms]
*5 All of UPS, WEL and DWS of the WELD1 section is set to 0, WELD2 cannot be
operated correctly. Only WELD2 setting cannot be performed. “E11 Weld
parameter error” will occur.
Remarks
If the value less than the effective digits for the time 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 “100.5” ms is input, the
effective digits for 100 ms or more is 1 ms, the set value is automatically corrected to
“100” ms when the screen is switched from the Welding condition setting screen to the
Monitor screen.
(d) TORCH
Select a torch No. to be used from TORCH 1 or TORCH 2.
When the “SCH & Torch select by I/O” in 4. (6)
(c) in the Switch select (1/2) screen
is set to ON, the external input takes priority.
TORCH 1 and TORCH 2 can be switched by connecting the optional torch selector.
[Initial value: TORCH1]
(e) SCH TYPE CHG
When this switch is depressed for about a second, the welding condition setting
mode is changed over to the SIMPLE mode.
The SIMPLE SETTING screen is displayed.
[Initial value: SIMPLE]
(f) Screen feed switch
The Schedule setting screen (2/2) is displayed.
(g) Screen return switch
The Schedule setting screen (1/2) is displayed.
