If spot time is changed during welding, this change
will not be carried into effect until next welding
process.
Fixed functions
The functions below are fixed and cannot be
connected and disconnected from the display:
Anti-freeze
The anti-freeze-function is always on. During MMA
and TIG welding the electrode sometimes sticks onto
the workpiece. The machine will register that the
electrode has stuck onto the workpiece, and will then
reduce the welding current so that the area of the
workpiece which has melted will harden, making it
possible to break off the electrode. Welding can then
continue in the usual way.
Torch cooling
The machine will automatically start cooling when
establishing the arc if the machine has been
mounted with a cooling module and a Migatronic
water-cooled torch. Cooling continues until 2½ min.

FAULT IDENTIFICATION

Overheating error
Welding is interrupted due to overheating if the
machine is used
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
o
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 decribed above,
please contact the MIGATRONIC service depart-
ment.
