Possible cause
Voltage recording faulty
[1]
A/D-channel error
Slope error
-Conditions violated.
Temperature error
Short circuit in welding circuit
[1]
before welding.
Secondary overvoltage
I>0 error
-
no ignition at process start (au-
tomated machines).
An arc interruption occurred
during welding with an automa-
ted system.
Internal error
The emergency stop circuit of
the power source has been acti-
vated.
After switching on the automa-
ted system, no wire feeder (DV)
was detected.
Wire feeder 2 not detected.
Open circuit voltage reduction
error.
Excess current detected on wire
feed mechanism.
Remedy
Eliminate short circuit in welding cir-
cuit.
remove external sensor voltage.
Request service.
Switch the machine off and on again.

cool down.
Eliminate short circuit in welding cir-
cuit.
Request service.

Request service.
Observe accompanying documenta-
tion for Bluetooth function.
Check wire feeding
Check load cable connections in
welding current circuit.
clean corroded surfaces on work-
piece before welding if necessary.
Check wire feeding.
Adjust welding speed.
Request service.
Disable the activation of the
emergency stop circuit (release pro-
tective circuit).
Check or connect the control lines of
the wire feeders;
Check the identification number of
the automated wire feeder (for 1DV:
number 1, for 2DV: each a wire fee-
der with number 1 and a wire feeder
with number 2).
Check control cable connections.
if necessary, disconnect external ma-
chine from the welding circuit.
Request service.
Do not place the liner in tight radii.
Check liner for smooth movement.
