Eliminate short circuit in welding cir-
cuit.
remove external sensor voltage.
Request service.
34
Electronics error
A/D-channel error
Switch the machine off and on again.
Request service.
35

47
B
Bluetooth error
-
Observe accompanying documenta-
tion for Bluetooth function.
48
B
Ignition error
no ignition at process start (au-
tomated machines).
Check wire feeding
Check load cable connections in
welding current circuit.
clean corroded surfaces on work-
piece before welding if necessary.
49
B
Arc interruption
An arc interruption occurred
during welding with an automa-
ted system.
Check wire feeding.
Adjust welding speed.
50
B
Program number
Internal error
Request service.
51
A
Emergency stop
The emergency stop circuit of
the power source has been acti-
vated.
Disable the activation of the
emergency stop circuit (release pro-
tective circuit).
52
No wire feeder
After switching on the automa-
ted system, no wire feeder (DV)
was detected.
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).
53
B
No wire feeder 2
Wire feeder 2 not detected.
Check control cable connections.
54
VRD error
Open circuit voltage reduction
error.
if necessary, disconnect external ma-
chine from the welding circuit.
Request service.
55
B
Excess wire feeder cur-
rent
Excess current detected on wire
feed mechanism.
Do not place the liner in tight radii.
Check liner for smooth movement.
