When the 1ST STAGE signal is input, VALVE 1 is output, and then SOL2 is output after
SQD. After SQD and SQZ, the sequence waits for the 2ND STAGE signal input. Next, when
the 2ND STAGE signal is input, the welding sequence after WELD1 starts.

n. MONITOR DISP MODE
Sets the monitor display. This function is invalid when the Program Unit is disconnected.
NORMAL
The monitor display is updated each time. It takes monitored value
computing time + display time (ms). Used when the part cycle time is
relatively slow.
* Communicated with the Program Unit each time welding is complete.
LAST
The monitor display is not updated. When the MONITOR screen is
updated, the last measured value is displayed. Used when the part cycle
time is relatively fast. Errors are also displayed only when updated
(communicated with the Program Unit).
* Not communicated with the Program Unit automatically.
o. RE-WELD
S
elect whether or not to supply welding current
again at the same location if the monitored current is
lower than the lower limit. The second welding
current will be 5% greater than the setting value.
Even when the welding current is supplied twice with RE-ELD, each count-up is done only
once.

None (below the lower limit setting for the second time). Once (The lower limit
setting or more for the second time). This cannot be used in combination with the off time
(OFF).
ON
Welding current will be
supplied again.
OFF
Welding current will not be
supplied again.
