Errors are displayed on the user interface. In addition, there are
status lights on the User Interface PC board and the Switch PC
board that contain error sequences.
Included in this section is information about the status lights and
some basic troubleshooting charts for both machine and weld
performance.
The status lights on the User Interface board, Crosslinc™, Input
board, Control board and the Switch board are dual-color LED’s or
green LEDs. Normal operation for each is described on the wiring
diagram.
Error conditions are indicated in the following chart.

Fault Codes
ERROR
CODE#
DESCRIPTION
POSSIBLE CAUSE
CORRECTIVE ACTION
6
Device that controls sequence
of the welding operation
halted due to an error.
Communication from the Power Source
failed before mapping was complete.
Weld Terminals Remote: Re-trigger to recover from error.
Weld Terminals Local: Toggle Remote/Local Switch to
recover from error.
18
ArcLink Auto-Mapping Failed. The machine could not properly
configure the devices that are attached
to it. This configuration problem could
be caused by the type of devices that
are connected to the machine or a
required device that is not connected.
Refer to the Operator’s Manual for proper configuration.
Verify all devices in the system are properly powered.
21
Device that controls sequence
of the welding operation
halted due to an error.
A component of the system
encountered an error during the
welding sequence and caused system
to stop. The component with the error
could be a wire drive, a user interface
or some other part fo the system.
Weld Terminals Remote: Re-trigger to recover from error.
Weld Terminals Local: Toggle Remote/Local Switch to
recover from error.
31
Primary Overcurrent.
Peak current through the transformer
primary has exceeded its threshold.
Check the input power (voltage and frequency). Verify that
the PC boards and input rectifier are in working condition
and proper input power and welding output cable
connections. Verify proper connections of main internal
power components. Power must be cycled to the machine
to reset the error.
36
Thermal Fault
Machine shut off output due to
elevated internal temperatures.
1. Check for material blocking intake or exhaust louvers.
• Blow air in the rear louvers to clear dirt from the fan.
Note: The Fan As Needed circuitry automatically shuts
off the fan 5 minutes after welding has stopped.
2. Welding output ratings may have been exceeded. Allow
the machine to cool down and reset.
Measure the thermostats at the Switchboard and replace if
defective
45
Output Voltage Limit
Exceeded
During OCV, the voltage at the studs
exceeded the allowable levels.
IF VRD is enables, the stud voltage exceeded 35 volts peak.
In standard operation, the stud voltage exceeded 113 volts
peak. Verify the voltage feedback leads are properly
connected inside the machine. Verify the input voltage in
/- 10% of the nominal value.
213
Communication Fault
CAN communication between the User
Interface PC board and the Switch PC
Board has been interrupted.
Power must be cycled to the machine to reset the error.
Visually inspect the CAN harness to ensure connections
and condition. Verify power supply to the User Interface
and Switch PC boards. Replace defective assemblies as
required.
If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your
Lincoln Authorized Service Facility for technical troubleshooting assistance before you proceed.
