Turn on the machine. To select the operating mode of the
cooling unit, proceed as follows:
1. Select any TIG welding mode.
2. Press the key Q and, while holding it down, press the
key R. Keep them pressed until the abbreviation H2O
appears on the display P.
3. Select the operating mode using the knob O, keeping in
mind that the numbers that appear on the display N
have the following meaning:
1 = Unit off,
2 = Continuous operation,
3 = Automatic operation.
To exit selection, briefly press the key Q.
NOTE: "Automatic mode" means that the cooling unit starts
when the torch button is pressed and stops running approx-
imately 2 minutes after the torch button is released.
Warning! If MMA electrode welding is selected, cooling is not
on and may not be selected. It is normal for the machine display
P to display, on start-up, the flashing abbreviation H2O.
3.5.1.4 Cooling unit for Art. 360
If using a water-cooled torch, use the cooling unit.
The trolley Art. 1432 is required to position and transport the
welding machine together with the cooling unit.
After filling the tank with coolant, connect the plug of the
mains cable to the socket AE of the welding machine, then
connect the 3-pin male patch connector to the connector AF.
3.5.1.5 Description of the cooling unit for Art.362 (Fig. 3)
AH
AG - Slot:
Slot to inspect the coolant fluid level
AH - Quick-fitting sockets:
Use only for TIG welding systems.
NOTE: they must not be linked together.
AI - Cap.
Turn on the machine.
Do not touch live parts and output terminals while the
machine is powered.
The first time the machine is turned on, select the mode
using the push-button A and the welding parameters by
means of the key R and the knob O as described in para-
graph 3.2.
The flow of inert gas must be set to a value (in liters per
minute) approximately 6 times the diameter of the electrode.
If you are using gas-lens type accessories, the gas through-
16
put may be reduced to approximately 3 times the diameter
of the electrode. The diameter of the ceramic nozzle must be
4 to 6 times the diameter of the electrode.
The most commonly used gas is normally ARGON, because
it is less costly than other inert gases, but you may also use
blends of ARGON with a maximum of 2% HYDROGEN for
welding stainless steel, and HELIUM or ARGON-HELIUM
blends for welding copper. These blends increase the heat
of the arc while welding, but are much more expensive.
If you are using HELIUM gas, increase the liters per minute
to 10 times the diameter of the electrode (Ex. diameter 1.6
x10= 16 lt./min of Helium).
Use D.I.N. 10 protective glasses for up to 75A, and D.I.N. 11
from 75A up.
3.6.
You may save parameters only after welding.
Pressing the push-button Q briefly makes a selection;
held down for more than 3 seconds, it saves the data.
Each time it is turned on, the machine always shows the
last welding condition used.
3.6.1.
Using the machine for the first time
When the machine is turned on, the display shows the sym-
bol PL; this disappears after 5 seconds, and a working cur-
rent is displayed. Follow the instructions in paragraphs 3.2
and 3.5, then proceed as follows to save the data in the pro-
gram P01:
· Briefly press the push-button Q (mem+mem-) the message
AI
P01 will appear flashing.
· Press push-button Q for more than 3 seconds, until the sym-
bol P01 stops flashing: at this point, the data have been
AG
saved.
· Obviously, if you wish to save in a program other than P01,
you should briefly press the push-button Q as many times as
necessary to display the desired program. P01 will be dis-
played the next time the machine is turned on.
PRESSING THE Q PUSH-BUTTON BRIEFLY MAKES A
SELECTION, WHILE HOLDING IT DOWN FOR MORE
THAN 3 SECONDS SAVES THE DATA.

The operator may edit and save a selected program by pro-
ceeding as follows:
· Press the push-button Q briefly and select the desired pro-
gram number.
· The symbol of free programs is flashing.
· Press the button AL and choose the welding procedure,
press the torch trigger A to select the mode (paragraph 3.1).·
Turn the knob O and set the welding current.
· If the TIG procedure has been selected, activate the LED V
(post gas) by means of the push-button R, and set the
desired value via the knob O (paragraph 3.1.)
· If you wish to adjust the "slope" times or other parameters,
after making these adjustments which are necessary in
order to weld, follow the steps described in paragraph 3.1.
· Weld, even briefly, and decide where to save
· To save in the previously selected program, press the
button Q for more than 3 seconds, until the number stops
flashing.
· To save in a different program, make your selection by
