Example: 60 A is programmed for the high-pulse current in a sector. During the process, a value of 55 A (–5 A) is mea-
sured: A warning message appears ("
High-pulse current too low
"). The process continues running. The operator can
carry out other measures (e.g. manual initiation of current slope-off).
Maximum HP current (alarm)
Upward deviation of the high-pulse current (HP): If the specified deviation (5 A) is reached, a warning message appears.
Example: 60 A is programmed for the high-pulse current in a sector. During the process, a value of 65 A (+5 A) is measured:
A warning message appears ("
High-pulse current too high
"). The process continues running. The operator can carry out
other measures.
Maximum HP current (abort)
Upward deviation of the high-pulse current (HP): If the specified deviation (+10 A) is reached, welding is aborted.
Example: 60 A is programmed for the high-pulse current in a sector. During the process, a value of 70 A (+10 A) is mea-
sured: The process is aborted. The gas post purge time is still complied with.
This method of functioning applies for the following parameters in the same way:
•
Minimum/maximum LP current
•
Minimum/maximum HP speed
•
Minimum/maximum LP speed
Minimum/maximum voltage
The minimum and maximum deviations are not specified for the arc. The absolute voltage values are provided instead.
There is no setpoint value for the arc voltage in the procedure which can be compared to the current measured value.
Minimum/maximum voltage (abort)
Welding is aborted when the value is reached.
Minimum/maximum voltage (alarm)
A warning message appears when the value is reached.
