7.2 Error messages (power source)
NOTE
A welding machine error is indicated by an error code being displayed (see table) on the
display on the machine control.
In the event of a machine error, the power unit is shut 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.
Category Error
a) b) c)
Possible cause Remedy
Error 1
(Ov.Vol) - - x Mains overvoltage
Error 2
(Un.Vol) - - x Mains undervoltage
Check the mains voltages and compare with
the connection voltages of the welding
machine
Error 3
(Temp) x - - Welding machine excess
temperature Allow the machine to cool down (mains
switch to "1")
Error 4
(Water) - - x Low coolant level Top off the coolant
Leak in the coolant circuit >
rectify the leak and top off the coolant
Coolant pump is not working > check excess
current trigger on air cooling unit
Error 5
(Wi.Spe) x - - Wire feeder, speedometer
error Check the wire feeder
speedometer is not issuing a signal,
M3.00 defective > inform Service
Error 6
(gas) x - - Shielding gas error Check shielding gas supply (for machines
with shielding gas monitoring)
Error 7
(Se.Vol) - - x Secondary excess voltage Inverter error > inform Service
Error 8
(no PE) - - x Earth fault between welding
wire and earth line
•(Phoenix 330 only)
Separate the connection between the
welding wire and casing or an earthed object
Error 9
(fast stop) x - - Fast cut-out
triggered by BUSINT X11 or
RINT X12
Rectify error on robot
Error 10
(no arc) - x - Arc break
triggered by BUSINT X11 or
RINT X12
Check wire feeding
Error 11
(no ign) - x - Ignition fault after 5 s
triggered by BUSINT X11 or
RINT X12
Check wire feeding
Wire feeder not detected.
Control cable not connected. Check cable connections Error 14
(no DV) - x -
Incorrect ID numbers
assigned during operation
with multiple wire feeders. Check assignment of ID numbers (see the
"Changing ID number of wire feeder"
chapter)
Error 15
(DV2?) - x - Wire feeder 2 not detected.
Control cable not connected. Check cable connections
Error 16
(VRD) - - x VRD (open circuit voltage
reduction error) Inform Service
Legend for categories (error reset)
