4-11 Description of Hard Arc Function
The hard-arc process is performed when micro-arc processes are performed the set number of times
within the set time.
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)].

4-12 Description of Ramp Up Function
Setting the ramp up function allows you to adjust the ignition ramp up and the time from the start of
electric discharge till when the command value is reached.
The setting can be changed on the front panel or through serial communication. * It is not possible to
switch during output operation.
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 4-9
