MAINTENANCE
Insufficient maintenance may result in reduced
operational reliability and in lapse of guarantee.
The NAVIGATOR 2500/3000 welding machines re-
quire virtually no maintenance. However, exposure to
extremely dusty, damp or corrosive air is damaging to
welding machines.
Periodical 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 -10oC.
WARRANTY REGULATIONS
All MIGATRONIC machines carry a twelve month
guarantee against hidden defects. Such defects must be
notified no later than two months after it has been noticed.
The warranty runs for twelve months after invoicing to
end customer.
The warranty becomes void by faults that can be
attributed to incorrect installation, pests, transport
damages, water- and fire damages, strokes of lightning,
use in connection with a synchronous generator and use
under abnormal conditions, which lies beyond the product
specification.
Lack of maintenance
There is a lapse of warranty if the product is not properly
maintained. E.g. if the product is dirty to such a degree
that cooling is hindered. The warranty does not cover
damages, which can be traced back to unauthorised and
incorrect repairs of the product.
Wear parts
The warranty does not cover wear parts (welding hoses,
welding cables and wire drive rolls)
Resulting damages
Use of the product must stop immediately after acknow-
ledgement of a defect in order to avoid further damage of
the product. The warranty does not cover resulting
damages due to use of the product after acknowledge-
ment of a defect. Moreover, the warranty does not cover
resulting damages on other items due to product defect.
