RESET MODE
Set the reset method to be applied when any ERROR signal is output
(
when
the current or voltage is out of the conditions set on
(5)MONITOR SET
Screen
)
.
If the ERROR signal is not reset, the next workpiece cannot be welded.

ATTENTION
In accordance with the Current Ranges, the value of detecting “No Current
Error” differs respectively. That is:
0.8kA or less in
HIGH
Range, 0.08kA or less in
LOW
Range
Therefore, if the current is set to 0.8kA or less in the operation of
HIGH
Range, “No Current Error” is detected.
Beforehand, change to
LOW
Range to perform the operation.
HIGH and LOW ranges do not affect Secondary constant-voltage effective
value control and Constant-phase control.
