■
PARAMETER SELECTION key - A
This is used to select the following welding parameters (if activa-
ted) and each time the key is pushed the welding machine moves
on to select the next parameter in the following order:
• THICKNESS OF WELDED ITEM ( ).
• WELDING CURRENT ( ).
• WIRE SPEED ( ).
■
MIG-MAG SYNERGIC PROCESS and PROGRAMME
SELECTION key
Allows:
• the selection of MIG-MAG synergic welding process;
• the selection of the individual welding PROGRAMME (in the pro-
cesses in which the programmes are present), according to the
welding process selected.
■
ENCODER knob - A
This is used to set and edit the PARAMETERS - A based on the
corresponding LED switched on and the value highlighted on the
DISPLAY PARAMETERS - A display, required for correct functio-
ning of the machine.
■
WELDING PROCESS SELECTION key
This is used to select the following welding processes and each
time the key is pushed the welding machine moves on to select
the next welding process in the following order:
• MIG-MAG sinergico ( ).
• MIG-MAG manual ( ).
• ELECTRODE (MMA) ( ).
• TIG with “Lift” striking ( ).
• JOB ( ).
■
SAVE “MEM” key (T ≥ 2 s)
It allows the saving of the parameters in the JOB.
It also allows one to view / change the parameters previously saved
in the JOB.
WARNING: No LED switches on when this key is activated!
■
PARAMETER SELECTION key - V
This is used to select the following welding parameters (if activa-
ted) and each time the key is pushed the welding machine moves
on to select the next parameter in the following order:
• ARC LENGTH ADJUSTMENT ( ).
• WELDING VOLTAGE ( ).
• ELECTRONIC INDUCTANCE ( ).
■
ENCODER knob - V
This is used to set and edit the PARAMETERS - V based on the
corresponding LED switched on and the value highlighted on the
DISPLAY PARAMETERS - V display, required for correct functio-
ning of the machine.
■
WELDING MODE SELECTION key
This is used to select the following welding modes (only for MIG-
MAG welding processes) and each time the key is pushed the
welding machine moves on to select the next welding mode in the
following order:
TWO STROKE (2T)
2T LED ( ) switched on
Pressing the TORCH TRIGGER starts the welding cycle, which
will stop when it is released.
FOUR STROKE (4T)
4T LED ( ) switched on
1) Pressing and releasing the TORCH TRIGGER will start the
welding cycle.
2) Pressing and releasing the TORCH TRIGGER will start the
welding cycle.
CRATER 2T
2T LED ( ) switched on - CRATER LED ( ) switched on
1) When the TORCH TRIGGER is pushed the arc ignites and the
parameters assume the values for the “initial crater” for a time
set by means of the CRATER START TIME (CSt) function.
After that the parameter values become those for “welding”
for a time defined by the SLOPE (SLo) function.
2) When the TORCH TRIGGER is released the parameters take
on the “final crater” values for a time set by means of the CRA-
TER END TIME (CEt) function, for a period of time set using
the SLOPE (SLo) function.
CRATER 4T
4T LED ( ) switched on - CRATER LED ( ) switched on
1) When the TORCH TRIGGER is pushed the arc ignites and the
parameters assume the values for the “initial crater”.
2) When the TORCH TRIGGER is released the parameters take
on the “welding” values for a time set using the SLOPE (SLo)
function.
3) When the TORCH TRIGGER is pushed again the parameters
take on the “final crater” values for a time defined using the
SLOPE (SLo) function.
4) Releasing the TORCH TRIGGER will end the welding cycle.
SPOT WELDING 2T
2T LED ( ) switched on - SPOT LED ( ) switched on
This is used so that on pressing the TORCH TRIGGER spot wel-
ding is done for a time period set beforehand (in seconds), after
which the arc switches off automatically.
STITCH WELDING 2T
2T LED ( ) switched on - SPOT LED ( ) flashing
To begin stitch welding:
1) Press the TORCH TRIGGER to start the welding current and
wire feed.
At this point the welder will perform automatically a succession
of a welded tracts followed by a pause, respecting the times
set in the functions STITCH WELD TIME (SAt) and STITCH
WELD PAUSE (Srt).
This procedure stops automatically only when the TORCH
TRIGGER is released.
2) When the TORCH TRIGGER is pushed again the torch be-
gins a new interval welding cycle.
■
SPECIAL FUNCTIONS key “Fx” (T ≥ 3 s)
This key is used to display and edit some parameters that are ne-
cessary and fundamental for welding and that have already been
set by the manufacturer in the factory.
The parameters vary depending on the welding process and mode
used, and are saved in the memory for each automatic welding
point (JOB).
WARNING: No LED switches on when this key is activated!
