Cebora INVERTER TIG Manual De Instrucciones página 15

Turn on the machine.
See chapter " SERVICE FUNCTIONS MENU " to select
the cooling unit operation mode.
3.5.2 Start-up
Do not touch live electrical parts and output terminals
when the machine is powered.
At fi rst start-up, select the operation mode by means of
button E and the welding parameters by means of P but-
ton and knob AA.
Warning! Settings for LEDs AO = start, Q = Hz, R = wave
balance can be selected in TIG AC mode only.
The inert gas fl ow must be set at a value (liters per minute)
approximately 6 times the electrode diameter.
If gas-lens type accessories are used, the gas delivery
must be reduced by approximately 3 times the electrode
diameter. The ceramic nozzle diameter must be between
4 and 6 times the electrode diameter.
• When you have fi nished welding, do not forget to
shut off the machine and close the gas cylinder valve .
3.5.3 Preparing the electrode.
Be especially careful when preparing the electrode tip.
WARNING: LOOSE HOT METAIL PARTS may cause per-
sonal injuries, fi res and damage the equipment; TUNG-
STEN CONTAMINATION may lower the quality of the
weld.
Use only a grinder equipped with adequate safety guards
to shape the tungsten electrode and wear protections for
face, hands and body.
To shape the tungsten electrodes, use a hard, fi ne-grained
abrasive grinding wheel used solely for this purpose.
Grind the tungsten electrode tip in a conical form and a
length 1.5 to 2 times the electrode diameter (fi g. 3).

3.6. SAVING
A long or short pressure of button AQ is used for pro-
grams to be saved, their restoring and saving.
Short pressure to select, long pressure to save.
Programs to be saved (memories) are displayed by
display U: fl ashing are free, non fl ashing contain al-
ready stored data.
3.6.1. Saving data from the PL program
When using the machine the fi rst time
Work programs and memories (P01... etc.) are always
displayed by display U, their selection is obtained by a
short pressure of button AQ.
Once all the parameters to be saved are decided, press
shortly button AQ, the display U will show the fl ashing
abbreviation P01 and display O will show three lines (---);
hold down the button AQ for more than 3 seconds, until
the symbol P01 stops fl ashing and a sound will signal that
data have been stored.
If a different program must be selected, hold down but-
ton AQ until the number of the selected program is dis-
played on display U.
3.6.2. Saving from a free program
The operator can change and save the selected program
using the following procedure:
Hold down button AQ shortly and select
the number of the selected program.
Do not touch live parts and output terminals while the
machine is powered.
Hold down button AT and select the welding process and
by means of the button E select the mode.
Turn knob AA and set the welding current.
If TIG process is selected, activate led X
(post gas) by means of button P and set by means of
knob AA the selected value.
After these settings that are required for saving, if you
wish to set the "slope" times or other times, follow the
procedure given in the corresponding paragraph.
To save the previously selected program hold down
button AQ for more than 3 seconds, until the program
number stops fl ashing.
3.6.3 Saving from a saved program.
Beginning with a previously saved program, the opera-
tor may modify the data in memory to update the pro-
gram itself, or to fi nd new parameters to be saved in an-
other program.
3.6.3.1 Up-dating
Once the machine is started, select the parameters
to be modifi ed and modify them: the abbreviation of the
selected program will then change from steady to fl ash-
ing.
Hold down for more than 3 seconds button AQ, display O
will show abbreviation Sto.
Hold down button AQ for more than 3 seconds, until the
program abbreviation P01 stops fl ashing and a sound
d
signals that data have been stored.
3.6.3.2 Saving from a new program.
Once the machine is started, select the parameters
to be modifi ed and modify them.
Press shortly button AQ until the selected program is dis-
played.
Hold down button AQ for more than 3 seconds until the
saving is confi rmed (program abbreviation changes from
