4-9 Description of Micro Arc Function
If the output voltage becomes equal to or less than the set voltage detection level, or if the output value
becomes equal to or greater than the set current detection level, an arc is detected and the micro-arc
process is performed.
The micro-arc process is performed for the set period of processing time.
During this processing time, it can be set whether to stop the output or enter a low output state. *
In addition, the monitoring of the the output voltage state starts after the processing time has elapsed,
and it can also be set whether to produce the output in the low output mode until the output voltage
reaches or exceeds the set value, or to return the output state to the original output state at high speed
regardless of the output voltage state. *
For instructions on how to set parameters, refer to [5-1-2 Parameter setting through front panel
operation].
For detailed menu structure, refer to [Table 4-8: Each parameter (ARC layer)].
*Low output processing and post-processing voltage monitoring are Option functions.

After the processing time has elapsed, the low output
