GAS FLOW ADJUSTMENT
When the unit is powered on the solenoid valve opens for 1 second.
This serves to fill the gas circuit.
P27
Open the gas solenoid valve by pressing and releasing the button.
Adjust the pressure of gas flowing from the torch by means of the
flow meter connected to the gas cylinder.
P27
Close the gas solenoid valve by pressing and releasing the button.
The solenoid valve closes automatically after 30 seconds.
TORCH LOADING
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 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 "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.
COOLING SYSTEM TEST
The message appears on the following
displays: P25
(any)
Press the button or torch trigger to repeat the checking procedure
for an additional 30 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 "AUTO"
Press and release the torch trigger.
This serves to start the cooler for 80 seconds to fill the torch cooling
