TRANSMIG 250i PROBLEMS/SERVICE
PROBLEMS AND ROUTINE SERVICE 5-2 Manual 0-5187
23 Weld Fault Welder detected a fault during
the weld process
Consult an Accredited CIGWELD Service
Provider if symptom recurs frequently.
24 Code Memory Fault Welder detected a fault in
program flash memory
Firmware image is corrupted. Consult an
Accredited CIGWELD Service Provider.
25 Nonvolatile Memory
Fault
Welder detected a fault in
parameter NVROM.
A. Welding may still be possible, but no weld
setting changes can be saved.
B. Consult an Accredited CIGWELD Service
Provider.
26 Unknown PCB Fault Welder control board cannot
identify an attached inverter
board and/or determine its
own identity
Consult an Accredited CIGWELD Service
Provider.
30 Service Mode Switch
Fault
SERVICE DIP switch is
enabled
Welding is disabled while SERVICE Mode DIP
switch is enabled. Disable SERVICE Mode
switch to resume welding.
31 Controller Fault Welder control board has
detected a hardware fault on
itself
Consult an Accredited CIGWELD Service
Provider if symptom recurs frequently.
33 Calibration Fault An output (current, voltage,
or motor) fault was detected
while attempting a calibration
process
A. Check integrity of welder cables, MIG Torch
or electrode holder and retry calibration.
B. Check MIG wire spool, feedplate area for
wire feed issues, correct and retry calibration
34 User Calibration
Abort
User-initiated abort/
interruption of an active
calibration process occurred
(usually, release of trigger too
early)
Restart/reselect calibration process and retry
calibration when ready.
35 Parameter Fault Welder control board has
detected a parameter out of
range
System Parameter re-initialization has been
automatically performed or is required
(Factory Default Reset)
Note 1: If the left display is alternate flashing "Err" and "Code" this is indicating that the fault was detected
but has either stopped occurring or is in the process of clearing itself. If this is the case, the flashing error
message will return to normal display functionality within 10 seconds unless another fault occurs. If the
left display shows a steady "Err" this is indicating that the fault is persistent and is still being detected.
Note 2: Flashing Amperage and Voltage displays (when welding) indicates that the machines maximum
output power rating (300A x 26.7V = 8kVA) is being exceeded and the system is automatically reducing
the output. If welding is ceased while the displays are flashing, the last values will be displayed for 10
seconds or until controls are adjusted..
