FAULT IDENTIFICATION
Overheating error
Welding is interrupted due to overheating if the
machine is used beyond the specifications mentioned
in chapter "Technical Data". The machine must
remain turned on and connected to the mains supply
as the fan continues until the machine has been
sufficiently cooled. Thereafter, the machine is
automatically switched in.
An overheating error is more oftenly seen if the
machine is used in surroundings with temperatures
above 40°C. It is not recommendable to place the
machine in direct sun light as this increases the
possibility of an overheating of the machine.
Mains error
The mains error arises if the mains voltage is too high
or low.
Please make sure that the mains plug is correctly
mounted and that all fuses are intact. Moreover,
please control that the mains voltage does not
exceed the technical specifications and that there are
no short-term voltage drops or voltage peaks.
Torch cooling error
This error can be seen by the text "Etc" in the
machine display. Turn off the machine if the cooling
water does not flow in the water-cooled torch. Make
sure that all hoses have a free passage, see chapter
"maintenance". Turn on the machine again when a
free passage has been established. Welding can then
be continued.
Other errors shown in the display:
If other errors arise than those described above,
please contact the MIGATRONIC service department.
MAINTENANCE
Insufficient maintenance may result in reduced
operational reliability and in lapse of guarantee.
The COMMANDER welding machines require
virtually no maintenance. However, exposure to ex-
tremely dusty, damp or corrosive air is damaging to
welding machines.
Periodically maintenance
In order to prevent problems arising, the following
procedure should be observed at least once a year or
as required.
- disconnect the machine from the mains supply and
wait 2 minutes before removing the front panels.
- clean the fan blades and the components in the
cooling pipe with clean, dry, compressed air.
- drain the cooling liquid out of the cooling module
and welding hoses. Remove dirt and flush with
pure water in the tank and cooling hoses. Fill up
with new cooling liquid. The machine is delivered
with a cooling liquid of type propylene glycol in the
ratio 1:3 which provides an anti-freeze solution up
to -10°C.
