6.6 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 to the torch in the case of high voltage arc strikes without any
Power-up with operation of the cooler set to "ON" or "AUTO" mode
A check is performed automatically of the presence of liquid in the cooling circuit and the cooler is
switched on for 30 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.

• If the problem persists rectify the cause of the alarm.
• During this checking operation, the setup menu can be accessed by pressing button S5
for 5 seconds.
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 "AUTO"
Press and release the torch trigger.
This serves to start the cooler for 80 seconds to fill the torch cooling circuit.
6.7 RESISTIVE CALIBRATION OF THE WELDING CIRCUIT
When the wire feeder is used with the associated cable bundle, the welding circuit "r" resistance must
be measured by using the calibration function. This allows to achieve a consistent welding quality when
the cable bundle length and the torch is changed. The welding circuit resistance depends on the cable
bundle and the torch used, therefore the calibration procedure must be repeated when these compo-
nents are changed.
CALIBRATION after power source RESET
If the power source total RESET is carried out, the calibration value will be replaced by the default value.
If a partial RESET is carried out, the measured value will be stored.
Calibration is not compulsory therefore, should the user decide not to carry it out, the machine will keep
the default value.
