MAINTENANCE

Lack of maintenance can lead to reduced reliability
and repeal of the guarantee.
Wire feed unit
This unit must be cleaned with dry, clean, com-
pressed air and maintained regularly at the wire feed
roll and the capillary tubes, as it is of great
importance for a satisfactory welding result and a
minimum of wear and tear that the wire passes
through the wire drive system without any de-
formations of the wire or the wire feed roll. The
contact tips must be checked often and changed if
the copper plating of the wire is damaged on its way
through the tips. Copper dust may prevent free
passage of wire through the torch liner. A weekly
control and cleaning of the capillary tubes and the
wire feed roll is recommended.
MIG/MAG hose
Great care should be taken to ensure that the
welding hose is not overloaded. It should not be
pulled over sharp edges, and heavy machines
should not run over it. The hose should be dis-
mantled every week and blown out with clean, dry
compressed air. The torch should be disconnected
during this process.
MIG/MAG welding torch
There are many parts in the welding torch that have
to be cleaned regularly. The main ones are the
contact tips and the gas shroud. During the welding
process, these parts are bombarded with spatter
that sticks in the shroud. Spatter should be removed
regularly. Add MIG-spray that loosens spatter.
During the cleaning process, the gas shroud should
be removed. Do not clean by banging or hitting the
torch.
Power source
With regular intervals dust should be blown out of
the power source with clean, dry compressed air.
Choked or blocked air intake and outlet may result in
overheating. The power source should be checked
and cleaned at least once a year by trained service
staff.
Water module
Waterlevel should be checked regularly. To ensure
reliable operation, always use Migatronic coolant
(part no. 99290510), mixed with water in the ratio
mentioned on the packing. If the level of coolant in
the tank falls so low that the machine is dis-
connected (error information in the control panel of
the current source), then extra coolant should be
added, using the filling nozzle. Coolant needs yearly
renewal.
