4.3 Alarms
Alarms occur when the welder does not successfully complete a weld cycle. Conditions
that cause alarms include overloads or hardware failures. In addition, alarms display when
you press a parameter selection switch while an active alarm exists.
When an alarm occurs, the Numeric Display on the front panel displays an alarm code. An
alarm code takes the form Error xx - where Error represents an alarm, and xx is the
number of the alarm code.
Alarms are classified into four types of alarms: Latching, Non-Latching, Non-Resettable,
and Latchable. Actions you can take to reset the welder depend on the type of alarm. The
following lists the four types of alarms:
4.3.1 Alarm Codes and Error Messages
The following Table contains descriptions and common causes and solutions for each alarm
code generated by the IW or IW+ welder.
Table 4.5 Alarm Types and Action
Alarm Type Action Required
Latching Press RESET before the next weld cycle can start.
Non-Latching
Correct the condition that caused the alarm. Once you correct the
condition, the alarm code disappears and the welder is ready to
run a weld cycle.
Non-Resettable
Correct the condition that caused the alarm. (A Non-Resettable
alarm usually occurs due to a hardware failure). Clear the alarm
by powering the welder OFF, then powering the welder ON. If the
alarm still appears, continue troubleshooting.
Latchable
Set the Alarm Latch Enable DIP switch to make a Latchable alarm
Latching or Non-Latching. To make and alarm Non-Latching, set
the DIP switch to OFF. For information on setting the Alarm Latch
Enable DIP switch, refer to your 2000 IW/IW+ Series Integrated
Welders Operating Manual.
