In case voltage exceeds the mentioned limits (voltage peaks), machine functions stop.
Reset the machine by switching the main ON/OFF knob.
The three-phase version detects even the right presence of the three current phases
and, should one of those fail for > 20 ms, machine functions stop and display will show
"
NO PHA
", reset the machine by switching the main ON/ OFF knob.
In the case of supply net frequency out from range of 46-64Hz the machine is stopped.
The appropriate alarm (
FRO/AC
) is shown in the display (this case can occurs when
the supply is coming from motor generator and the frequency goes outside the limits of
46-64 Hz).
Wire feeder status
The wire feeder is digitally controlled, and ever, the wire speed has the right value, in
the case that something doesn’t work properly two alarms indicate the kind of failure.
Water cooler unit status
When the generator is equipped with the cooling unit, the correct
cooling liquid circulation is constantly controlled. The cooling unit
works only when MIG/MAG processes is activated.
After welding, the water cooler unit will continue to work for 180s.
The cooling unit pump is controlled manually or automatically by
the switch auto-manual on the interface board in the welding
machine. It keeps working under manual mode, while, in Auto
mode, works only by switching the torch trigger, and stops after the
welding job is finished.
Long inactivity periods may damage the cooling unit pump or
generate momentary re-start problems. First ensure the presence
of liquid inside the tank and control the right positioning of the limit according to the
mark on the back panel
Following instructions may help:
a) Unplug the water-out blue hose from the machine rear panel and plug a temporary
hose.
b) Push & release the torch trigger once: cooling unit pump test should be activated
for 15 seconds.
c) Cooling liquid should flow from the temporary hose: if not, repeat the pump test as
above.
Warning:
The cooling liquid flows out of the blue fast socket at a high speed.
Please use a tank to receive the liquid.
