7.3 Warnings
Depending on the display options of the machine display, a warning message is displayed as follows:
Display type - machine control
Graphic display
two 7-segment displays
one 7-segment display
The cause of the warning is indicated by a corresponding warning number (see table).
• In case of multiple warnings, these are displayed in sequence.
• Document machine warning and inform service personnel, if required.

Possible cause
A shutdown is imminent due to excess temperature.
[2]
Check shielding gas supply.
[3]
Flow rate (<= 0.7l/min / <= 0.18 gal./min)
Only a small amount of wire is left on the spool.
Wire feeder not connected, automatic circuit-breaker of wire
feed motor (reset the tripped automatic circuit-breaker by ac-
tuating).
The welding circuit inductance is too high for the selected
welding task.
One of several partial inverters is not supplying welding cur-
rent.
[3]
Coolant (>= 65°C / >= 149°F)
The actual value of a welding parameter is outside the spe-
cified tolerance field.
The resistance in the welding circuit is too high. Check earth
connection.
Fault of wire feeder, permanent overload of the wire drive.
Overcurrent detection of the main WF drive.
JOB selection was not performed because the JOB number is
unknown.
Overload of the slave WF drive (front drive push/push system
or intermediate drive).
Fault of wire feeder, permanent overload of the slave WF drive
(front drive push/push system or intermediate drive).
Wire feeder not connected, automatic circuit-breaker of wire
feed motor (reset the tripped automatic circuit-breaker by ac-
tuating).
