Save from a saved program
Beginning with a previously saved program, the operator
may edit the data in memory to update the program itself, or
to find new parameters to save in another program.
3.6.3.1 Update
· After turning on the machine, select the parameters to be
edited and edit them.
· Weld, even briefly.
· Hold down the Q button for more than 3 seconds, until the
save is confirmed (program symbol changes from flashing to
steady).
3.6.3.2 Save in a new program
· After turning on the machine, select the parameters to be
edited and edit them.
· Weld, even briefly.
· Briefly press the selector Q until the desired program is dis-
played.
· Hold down the Q button until the save is confirmed (pro-
gram symbol changes from flashing to steady).
4 REMOTE CONTROLS
The following remote controls may be connected to adjust
the welding current for this welding machine:
Art. 1270 TIG torch button only.(air-cooling)
Art. 1273 TIG torch button only.(water-cooling)
Art. 1266 TIG torch UP/DOWN.(air-cooling)
Art. 1274 TIG torch UP/DOWN.(water-cooling)
ART. 193 may be used in any TIG welding mode with this
accessory.
Remote controls that include a potentiometer regulate
the welding current from the minimum to the maximum
current set via the knob O.
Remote controls with UP/DOWN logic regulate the
welding current from the minimum to the maximum.
The remote control settings are always active in the PL pro-
gram, while they are not active in a saved program.
5 MAINTENANCE
Any maintenance operation must be carried out by qua-
lified personnel in compliance with standard CEI 26-29
(IEC 60974-4).
5.1 GENERATOR MAINTENANCE
In the case of maintenance inside the machine, make
sure that the switch AC is in position "O" and that the
power cord is disconnected from the mains.
It is also necessary to periodically clean the interior of the
machine from the accumulated metal dust, using com-
pressed air.
5.2
PRECAUTIONS AFTER REPAIRS.
After making repairs, take care to organize the wiring so that
there is secure insulation between the primary and secon-
dary sides of the machine. Do not allow the wires to come
into contact with moving parts or those that heat up during
operation. Reassemble all clamps as they were on the origi-
nal machine, to prevent a connection from occurring
between the primary and secondary circuits should a wire
accidentally break or be disconnected.
Also mount the screws with geared washers as on the ori-
ginal machine.
