MAINTENANCE
Lack of maintenance can lead to reduced reliability
and cancellation of the guarantee.
Power source
At regular intervals all dust should be blown out of
the power source with clean, dry compressed air.
Choked or blocked air intake or air outlet can result
in overheating of the machine. The power source
should be checked and cleaned at least once a year
by trained service staff.
Torch cooling unit
The water level should be checked regularly. To
ensure reliable operation, always use MIGATRONIC
cooling liquid (part no. 99290510), mixed with water
in the ratio mentioned on the packing. If the level of
cooling liquid in the tank falls so low that the machine
is switched off (error information in the control panel
of the current source), then extra cooling liquid
should be added, through the filling neck. Cooling
liquid needs to be changed annually.
DISPLAY OF ERRORS
Three error situations can be displayed: Machine
overheating error, mains error and torch cooling
error. All errors are displayed for as long as the error
exists.
Machine overheating error
Origin: Overheating of the machine due to
incorrect use, e.g. exceeding the
duty cycle of the machine for the
welding current in use.
Consequence: The welding process is interrupted
and gas post-flow starts. The LED
with the symbol for overheating error
is illuminated. Fan runs at max.
speed.
Remedy: If the error is not caused by incorrect
use, MIGATRONIC's Service De-
partment has to be called in.
Mains error
Origin: The mains error arises if the mains
voltage is too high or low.
Consequence: The welding process stops and gas
post-flow starts. The LED with the
symbol for mains error is illuminated.
Fan runs at max. speed.
Remedy: If the error is not caused by incorrect
use, MIGATRONIC's Service De-
partment has to be called in.
Torch cooling error
Origin: There is no flow or insufficient flow
of cooling water in the torch.
Consequence: The welding process is interrupted
and gas post-flow starts. The LED
with the symbol for torch cooling
error is illuminated.
Remedy: Refill the water tank and check the
hose assembly. Please note that air
in the system can prevent the pump
from working. In such cases it may
be
machine several times.
