Depending on the options of the machine display, a fault is shown as follows:
Display type - machine control
Display
Graphic display
two 7-segment displays
one 7-segment display
The possible cause of the fault is signalled by a corresponding fault number (see table). In the case of an
error, the power unit shuts down.
The display of possible error numbers depends on the machine version (interfaces/functions).
• Document machine errors and inform service staff as necessary.
• If multiple errors occur, these are displayed in succession.
• Document machine errors and inform service staff as necessary.
• If multiple errors occur, these are displayed in succession.

Possible cause
Remedy
a) b) c)
1
Mains overvoltage
Check the mains voltages and compare with
the connection voltages of the welding ma-
chine
2
Mains undervoltage
3
Excess temperature of
welding machine
Allow the machine to cool down (mains
switch to "1")
4
Coolant error
Fill coolant
Turn on pump shaft (coolant pump)
Check overcurrent trip of air cooling unit
5
Wire feeder, tachometer error Check the wire feeder
tachometer generator sends no signal,
motor control defective > inform Service.
6
Shielding gas error
Check shielding gas supply (for machines
with shielding gas monitoring)
7
Overvoltage on secondary
Inverter error > inform Service
8
Wire error
Separate the electrical connection between
welding wire and housing or an earthed
object
9
Fast shutdown
Rectify error on robot
(Interface for automated welding)
10
Arc interruption
Check wire feeding
(interface for automated welding)
11
Ignition error (after 5 s)
Check wire feeding
(interface for automated welding)
13
Emergency stop deactivation Check the emergency stop switch of the
interface for automated welding
14
Wire feeder detection
Check cable connections
