Create and memorize new automatic
welding spots
After establishing a new welding spot (see paragraph "AUTO-
MATIC welding procedure") proceed as follows:
• Press the RUN/MEM key (AUT led on) until the first welding
spot free and/or available starts flashing on the PROGRAMME
DISPLAY (dVP);
• Press the RUN/MEM button until "Sto" appears on the dVP dis-
play and then release the button;
• After completing the saving operation the programme will set
itself automatically on the saved welding spot.
NOTE: The creation of an automatic welding point implies the
memorisation of all the corresponding special functions.
Call up automatic spots memorized
beforehand
The AUTOMATIC welding procedure must be entered to backtrack
previously memorized automatic jobs, then the PROGRAMME
SCROLLING keys must be pressed to select and view the memo-
rized automatic jobs.
Copy and change automatic
welding spots
After entering the automatic welding spot that you want to copy or
change proceed as follows:
• Keep pressing the WELDING MODE SELECTION key for 3
seconds; this operation will take the machine to the manual and
the synergic mode so that all the parameters memorized for this
spot can be corrected. More than one setting may be changed
this way and automatically saved by writing over the one set
previously (therefore changing it) or else it can be memorized in
another programme (see paragraph "Creating and memorizing
new automatic jobs"). Use the PROGRAMME SCROLLING key
to select the position where you want to memorize the welding
spot. Press the RUN/MEM key for memorizing until the wording
"Sto" appears on the PROGRAMME DISPLAY (dVP).

To delete an automatic welding point

To delete a memorized automatic welding point for AUTOMATIC
type work related to any process, it is necessary, with welding turned
off, to proceed in the following manner:
• Position the machine on the automatic welding point you want to
delete;
• Press the RUN/MEM button for 5 seconds;
• On the display will appear "CLR";
• When you stop pressing the button, the automatic welding point
selected will be deleted.
Having deleted the automatic welding point, the machine will posi-
tion itself on a valid automatic welding point. If there are no valid
automatic welding points, the machine will display "NA1", as hap-
pens when you enter AUTOMATIC mode and there are no auto-
matic welding points present. The free space can be occupied by
a new automatic welding point or it can be left free to be used as
a sequence terminator (see paragraph "Welding sequences").

How to use automatic welding spots

The automatic points are contained in one memory position (MAX
99 points) so they can be listed in sequence with the UP/DOWN
commands on the torch; with the processes unchanged, the pas-
sage from one point to another can occur during the welding; to
allow this, there is a programmable "ACS" parameter for the linear
connection of the synergic points during the passages.

Welding sequence

It is possible to perform welding jobs using a sequence with more
than one automatic welding point previously memorized by the user.
It is also possible to change the automatic point during welding, as
long as an up/down type of torch is used.
CONCEPT OF "SEQUENCE OF AUTOMATIC
WELDING POINTS"
A "sequence of automatic welding points" is a group of a certain
number of automatic welding points saved by the user. The group
is marked off by leaving an empty automatic welding point at the
beginning of the group and another empty one at the end.
MEMORIZING A WELDING SEQUENCE
To set a welding sequence, you must:
1) Check that you have a free point before the first automatic point
(before position 1 and after position 99 there are always two
free automatic welding points that mark off the sequence. There-
fore, it is not necessary to insert an empty point in position 1 or
position 99);
2) Set the machine to the program desired, in MANUAL or
SYNERGIC mode with the settings you intend to use for the
automatic point;
3) Press the SPECIAL FUNCTIONS button to access the special
functions;
4) Select by means of the ENCORDER 1 knob, the ACS param-
eter;
5) With the ENCODER 2 knob, set the slope in A/s you want to
use to shift towards that automatic welding point;
6) Exit the special functions by again pressing the SPECIAL
FUNCTIONS button;
7) Save the current settings in an automatic welding point (see
paragraph "Creating and memorizing new automatic welding
points");
8) Repeat the procedure from point 2 for all the automatic welding
points you wish to add;
9) Check that there is a free point after the last point inserted or
else delete it (see paragraph "Deleting an automatic welding
point").
USING THE SEQUENCES
To activate a welding sequence, beginning with an Mig/Mag, Pulsed
or Double Pulsed process, press the TYPE OF WORK button to
enter the AUTOMATIC mode. This involves:
• Memorizing the last active non-automatic process before enter-
ing the AUTOMATIC mode;
• Selecting the last automatic point used (e.g. the last one memo-
rized), or, if this does not exist, the first existing one. Keep in
mind that it is possible that the point belongs to a different proc-
ess from the one presently selected.
When welding is not active, the LIST PROGRAMS buttons located
on the front panel list all the automatic welding points that have
been memorized, changing the process automatically when the
point requires it. With the right button (+) and the left button (-) on
the torch (if it is of the up/down type) it is only possible to move
among the points belonging to the same sequence.
Pressing the TYPE OF WORK button takes you back to the last
active setting before entering AUTOMATIC mode, while changing
the welding process if necessary.
After you select an automatic welding point, it is possible to begin
welding within the relative sequence. The LIST PROGRAMS but-
