A. TORCH LOADING
Make sure the torch in use is correctly sized in relation to the welding current required and for the available and selected cooling type. This
prevents the risk of burns to which the operator is potentially exposed, potential faults, and irreversible damage to the torch and the system.
If a torch is installed or replaced while the unit is running, the circuit of the newly installed must be filled with coolant to avoid the risk of damage
Power-up with operation of the cooler set to "ON" or "AUT" mode
A check is performed automatically of the presence of liquid in the cooling circuit and the cooler is switched on for 15 seconds.
If the coolant circuit is full, the power source sets up in the most recent stable welding configuration.
If the coolant circuit is not full, all functions are inhibited and there will be no output power present.
COOLING DEVICE ALARM
Press the button or torch trigger to repeat the checking procedure for an additional 15 seconds.
(any)
If the problem persists rectify the cause of the alarm.
Power-up with operation of the cooler set to "OFF"
Operation of the cooler and the cooler alarm are disabled.
Welding is performed without liquid cooling of the torch.
Torch change-over with operation of the cooler set to "ON"
Press and release the torch trigger.
This serves to start the cooler for 15 seconds to fill the torch cooling circuit.

ALARMS MANAGEMENT

This LED illuminates if an incorrect operating condition occurs.
An alarm message appears on the following display: D2
MESSAGE MEANING
Overheating alarm
Indicates tripping of the welding power
source thermal protection.
THERMAL Leave the unit running so that the
ALARM! overheated components cool as rapidly
as possible.
When the unit has cooled, the welding
power source will reset automatically.
COOLING Cooler alarm
DEVICE Indicates insufficient pressure in the torch
ALARM liquid cooling circuit.

to the torch in the case of high voltage arc strikes without any liquid in the circuit.
The message appears on the following displays: D2
Tab. 2 - Alarm messages
All functions disabled.
Exceptions:
- cooling fan.
- cooler (if switched on).
All functions disabled.
Exceptions:
- cooling fan.
The alarm message persists on the display until the first operation is
performed on the user interface.
Cooler ON: the alarm is signalled as long as the unit alarm is active
and the cooler presence signal persists.
Cooler OFF: the alarm is never signalled, irrespective of the
circumstances.
Cooler AUT: the alarm is signalled at the times in which the unit is
running; the alarm signal occurs as long as the unit presence signal
persists.
WARNING!
EVENT CHECKS
- Make sure that the power required by the
welding process is lower than the maximum
rated power output.
- Check that the operating conditions are in
compliance with the welding power source
data plate specifications.
- Check for the presence of adequate air
circulation around the welding power source.
- Check that the connection to the cooler is
correct.
- Check that the O/I switch is set to I and that it
illuminates when the pump is running.
- Check that the cooler is filled with coolant.
- Check that the cooling circuit is liquid tight,
notably the torch hoses and the internal
connections of the cooler.
