NB. Not all errors are present on in this manual. Some errors and alarms are specic for the welding process used,
which should be not available on this model.
Undervoltage error “Err. LInE”.
This error occurs when the machine measures undervolatge condition.
Error solving:
The machine will start again automatically to function when the voltage grow up to an uncri-
tical value.
Thermal overload error “Err. tHr”.
This error occurs when the machine is in thermal overload due to an excessive overheat-
ing.
Error solving:
The machine will start again to function when temperature will decrease up to an uncritical
value.
Low coolant level error “Err. H2O”.
This error can appears only if the machine works in MIG/MAG mode. If the water cooling
unit is switched on, the error occours if there are leak in the coolant circuit, less water into
the tank, coolant pump is not working, sensor damaged.
Error solving:
The machine will start again to function when the error is solved, the water cooling unit is
switched off by the button on front panel and turn on again.
Torch button pressed “trC on”.
MIG/MAG torch button pressed during the machine switch on phase.
The error occours if the machine, in switch on phase, recognize that the torch button is
pressed.
Error solving:
Release the torch button during this phase or check the torch.
