Fault Identification / Maintenance - Migatronic FLEX XMS Manuel D'instruction

Copy of parameters
The AUTO key pad fullfils a special function during
the installation of a synergic program and can be used to
move a standard parameter to all points on the synergic
curve. A parameter which is to have one value through-
out the program can be inserted at all points in one
operation.
Transferring synergic programs
between machines
It is
necessary to move a synergic program from one
machine to another machine.
In such cases, the program from the synergic library on
the second machine must be the same as the basis
program used on the first machine.
The program is transferred by using the same method of
synergic editing used when installing a new program. The
RECALL key pad and the key pad in the synergic section
are pressed at the same time and the parameters at all
points of the synergic curve can now be read. This
information is now installed in the second machine in the
same way as a new program is prepared. All details of
wire feed speed, voltage, choke value and pulse
parameters are installed without actually welding with the
second machine.
Installation of synergic current
To install the current the RECALL key pad is
pushed and the left hand display window then shows the
current which can be adjusted with the appropriate key
pads. There must be no prior welding at the actual point
before the RECALL key pad is pushed, otherwise the
display will show only the last measured current. A further
push on the RECALL key pad allows the display and
installation of wire feed speed/pulse current etc. to
proceed.
Correcting a synergic program
If it is found that a synergic program
needs correction it is possible to make
adjustments to one or more points on the synergic curve.
Synergic editing is selected with a push on the RECALL
key pad and a push on the key pad in the synergic
section. The synergic key pad is used to move to the
required point where the parameter(s) can be adjusted
before synergic editing is ended with one or more pushes
on the synergic key pad.
Indicator of change in synergy
If the program in a machine is different from the
program in the synergic library, a full stop appears after
the program number.
possible and sometimes
FAULT IDENTIFICATION
Four possible faults can be registered by the machine,
with three of these faults shown as fault codes in the
display windows. Any faults are displayed for as long as
the faults exist, and if several faults arise at the same
time they are displayed in turn.
Mains supply fault
Supply fault 1 occurs if there is over- or under-voltage
from the electric mains supply. The machine will stop the
welding current and start the gas post-flow. Welding can
be restarted when the mains supply is corrected.
Overheating fault
The overheating indicator is illuminated if the
machine becomes overheated. The fault is indicated with
a yellow light and the machine will start the current slope-
down process and then the gas post-flow. If the fault has
not been caused by incorrect practice then the service
department must be called in. Otherwise, wait for the
machine to cool down with the machine switched on so
that the cooling fan continues to operate.
Torch cooling fault
This fault indicates that the torch cooling liquid is not
circulating properly. The machine stops the welding
process by starting current slope-down and then gas
post-flow. The water module must be filled and the torch
hoses checked for any leaks which must then be
repaired. If the fault does not disappear the service
department must be called in.
Wire feed unit fault
The wire feed motor is overloaded. If the wire feed unit
has been used correctly - service department must be
called in.
MAINTENANCE
Only first-call materials are used in the development and
production of MIGATRONIC welding machines. However
good the materials that have been used, and no matter
how careful the construction, an advanced product such
as a welding machine requires your care and attention if
it is to operate perfectly for many years to come.
Lack of maintenance can lead to reduced reliability and
cancellation of the guarantee.
Power source
The power source should be blown clear of dust with
clean dry compressed air at low pressure. Choked or
blocked air inlet or outlet can lead to overheating. The
power source should be checked and cleaned at least
once a year by trained service staff.
Torch cooling module
The level of the liquid must be checked regularly and
maintained at the correct level. For safe operation
MIGATRONIC cooling liquid should always be used in
accordance with the dilution instructions on the bottle.
The cooling liquid should be changed once a year.
