SAVE & RECALL
Use the button T5 to save and recall the pa-
rameters set by the operator.
To save the setup proceed as follows:
• Hold the button until the display views the
letter P followed by a number corresponding
to the operator point where the adjusted wel-
ding parameters can be saved in.
• Turn the knob 2 to choose the program
number to save in.
• To save the program keep the button T5
pressed. The wording SAV will appear on the
display.
To recall a saved program proceed as follows:
• Hold the button until the display shows the
letter P followed by a number, the operator
point where the adjusted welding parameters
are saved in.
• Turn the knob 2 to choose the number of
the desired program.
• Press the button T5 to load all the welding
parameters. The wording LOD will appear on
the display.
The system automaticaly exits the function
Save and Recall five seconds after the last
operation without saving or recalling any ope-
rator point.
When an alarm occurs, the generator's di-
splay blinks "Err" -> "Type of error"
Types of errors that can be displayed:
Input voltage too low (Check the
oU
supply voltage)
Input voltage too high (Check the
uU
supply voltage)
Missing of one phase (Check the
PL
supply voltage and the right connection of the
generator)
Output current too high (Switch off

ROUTINE MAINTENANCE
WARNING! PRIOR TO ANY INTERVEN-
TION MAKE SURE THE MACHINE IS
DISCONNECTED FROM THE POWER
SOURCE.
The efficiency of the welding equipment over
time is directly related to the frequency of
the maintenance operations. In the particular
case of welding machines, simply cleaning
their internal parts is sufficient; this must be
carried out more often if the workplace is par-
ticularly dusty.
Togliete la copertura.
• Remove the cover.
• Clear all traces of dust from the internal
parts of the generator using compressed air
with pressure below 3 kg/cm.
• Check all electric connections, making sure
that all screws and nuts are well tightened.
• Replace any deteriorated parts.
• Put the cover back on.
• After all these steps, the generator is ready
to work again, according to the instructions
contained in this manual.
