CTR12000
Fault
Workpieces stick to the electrodes.
Poor welding spot.
Welding spatter
Burnt spots or spots with craters or
imprints.
DANGER
41644, EN - rev. 2, 2012-09
Possible cause
Excessive welding current.
Unsuitable electrode caps.
Insufficient electrode pressure.
Insufficient welding current, welding time and/or
energy applied.
Electrode pressure is too high.
Electrodes are in poor condition, diameter is too
large.
Wrong program has been selected.
Wrong adjustment of total material thickness.
Poor sheet position, not close-lying.
Color or dirt between the sheets.
Poor contact between the workpieces or
between the workpiece and the electrode
Excessive welding current, welding time and/or
energy applied.
Current slope-up time is too short.
Electrode diameter is too large, worn electrode.
Insufficient electrode pressure.
Excessive welding current, welding time and/or
energy applied.
Insufficient electrode pressure.
Deformed electrode caps.
Poor sheet position, not close-lying.
General information on troubleshooting and remedy actions.
Only qualified electricians are allowed to open up power source and mains
plug.
ATTENTION! Prior to any work on open power source, disconnect the
machine from the mains and discharge the intermediate circuit.

Solution
Reduce welding power.
Use correct caps.
Increase contact pressure.
Increase welding current and/or time,
create special program with suitably
adapted parameters, if necessary.
Reduce contact pressure.
Clean electrodes, reshape and restore
correct dimensions, replace electrode
caps, if necessary.
Correct selection.
Correct adjustment.
Correct
Clean.
Increase electrode pressure.
Reduce welding current, energy and/or
time, create special program with suitably
adapted parameters, if need be.
Increase slope-up time.
Clean electrodes, reshape and restore
correct dimensions, replace electrode
caps, if necessary.
