Over current
150 A Fuse
No-current
Power is turned off in the following cases:
a.
When a secondary current is not detected in Secondary constant-
current effective value control, Secondary constant-power effective
value control, or Constant-phase control.
b.
When a primary current is not detected in Primary constant-current
effective value control or Primary constant-current peak value
control.
No-voltage
Under Secondary constant-voltage effective value control or Secondary
constant-power effective value control, the supply of current is stopped
when a secondary voltage cannot be detected.
Temperature
Overheating of power unit of inverter and welding transformer are
detected.
Self-diagnostic error
Setting dates (e.g., schedule settings) are diagnosed.
Setting accuracy
(Note 3)
Within ±3% of full scale
Repetition accuracy
(Note 3)
Within 4% of full scale
FORCE
Monitor Accuracy
Within 2% of full scale
