There are four types of alarms. Responses to these are described below:
•
Non-Resettable —
power the welder OFF and then back ON to
clear this alarm. Used for hardware failures.
•
Latching —
press RESET before the next weld cycle can start.
•
Non-Latching —
once the condition that caused the alarm is clear,
the alarm message will no longer be displayed. A weld cycle can
run as soon as this clears.
•
Latchable —
based on the setting of the Alarm Latch Enable DIP
switch. If the DIP switch is OFF, this group of alarms will become
non-latching alarms. If the DIP switch is ON, this group of alarms
will become latching alarms. (For further information, refer to
Section 3.9 "DIP Switches.")
