WARNING!
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 torch
must be filled with coolant to avoid the risk of damage to the torch in the case of high voltage arc
strikes without any liquid in the circuit.
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 configura
-
tion.
○ If the coolant circuit is not full, all functions are inhibited and there will be no output power present.
UNIT ALARM!
: The message will appear on display
D1
Press the (generic) button
to repeat the checking procedure for an additional 15 seconds.
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.
- STARTING CURRENT
○ The value of this parametercan be set as a percentage of the welding current or as an absolute
value expressed in Amperes.
- FINAL CURRENT
○ The value of this parameter can be set as a percentage of the welding current or as an absolute
value expressed in Amperes.
- HF CURRENT
○ This parameter establishes the current value during HF discharge. The value of this parameter
can be set as an absolute value or in SYN.
○ With SYN setting the HF current value is calculated automatically on the basis of the pre-set weld
-
ing current value.
Consequences of a higher value:
•
Arc striking is facilitated, even on very dirty workpieces.
•
Risk of piercing excessively thin gauge workpieces.
- HF TIME
○ This parameter defines the maximum high frequency (HF) arc strike duration.
