9. Timing Chart
9-12
1-3 Setting
Similarly in the following part, weld current is supplied on the consecutive 3
SCHEDULE No.’s.
Weld current is supplied through the transformer selected at Transformer No.
(TR#) in each SCHEDULE Screen.
The Squeeze Delay Time (SQD) is added in the first weld current only.
1-4 Setting
Weld current is supplied on the consecutive 4 SCHEDULE No.’s.
Weld current is supplied through the transformer selected at Transformer No.
(TR#) in each SCHEDULE Screen.
The Squeeze Delay Time (SQD) is added in the first weld current only.
NG/CAUTION during Weld Current Supplied
When the errors of Upper Limit (H) and Lower Limit (L) of the weld current,
voltage, power and resistance are set as the setting of NG, the equipment stops
by the NG Signal at the occurrence of the errors. When the errors of them are
set as the setting of CAUTION, the CAUTION Signal is generated after
completing all the supply of weld current.
Concerning the errors of CAUTION when the count-up of a counter has reached
the preset counter value, the CAUTION Signal is generated after completing all
the supply of weld current.
Concerning NG/CAUTION in other judgment, the equipment stops at the
occurrence of NG/CAUTION.
Note) The monitor is not redisplayed when the weld current is not supplied in the
schedule (the weld time is 0 ms).
Also, the next welding starts, redisplaying the monitor is interrupted.
Therefore, when the last schedule of transformer changeover is set not to
supply the weld current, the previous monitor is remained displayed.
