3.3. GENERAL NOTES

Before using this welding machine, carefully read the
standards CEI 26/9 - CENELEC HD 407 and CEI 26.11 -
CENELEC HD 433. Also make sure the insulation of the
cables, electrode clamps, sockets and plugs are intact, and
that the size and length of the welding cables are compatible
with the current used.
3.4. MMA WELDING (MANUAL METAL ARC)
- This welding machine is suitable for welding all types of
electrodes, with the exception of cellulosic (AWS 6010)*.
- Make sure that the switch A14 is in position 0, then connect
the welding cables, observing the polarity required by the
manufacturer of the electrodes you will be using; also
connect the damp of the ground cable to the workpiece, as
close to the weld as possible, making sure that there is good
electrical contact.
- Do NOT touch the torch or electrode holder simultaneously
with the earth clamp.
-Turn the machine on using the switch A14.
- Select the MMA procedure by pressing the button C: LED A
lit.
- Adjust the current based on the diameter of the electrode,
the welding position and the type of joint to be made.
- Always remember to shut off the machine and remove the
electrode from the clamp after welding.
If you wish to adjust the Hot-start (LED G) and Arc force
functions (LED I), see the previous paragraph.

3.5 . TIG WELDING

This welding machine is suitable for welding stainless steel,
iron, or copper using the TIG procedure. Connect the earth
cable connector to the positive pole (+) of the welding
machine, and the clamp to the workpiece as close as
possible to the welding point, making sure there is good
electrical contact.
Connect the power connector of the TIG torch to the negative
pole (-) of the welding machine.
Connect the torch connector to the welding machine
connector A10.
Connect the torch gas hose fitting to the fitting A8 on the
machine, and the gas hose from the cylinder pressure
regulator to the gas fitting A13 on the rear panel.
If using a water-cooled torch, use the cooling unit.
After filling the tank with coolant, connect the plug of the
mains cable to the socket A15 of the welding machine, then
connect the 3-pin male patch connector to the connector
A12.
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-buttons C, Z and A4 and the welding
parameters by means of the key H and the knob Q as
described in paragraph 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
throughput 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 x
10= 16 It./min of Helium).
Use D.I.N. 10 protective glasses for up to 75A, and D.I.N. 11
from 75A up.
3.5.1 Cooling unit (optional art. 560010).
When using a water-cooled torch, use the cooling unit.
To select the cooling unit working mode, proceed as follows:
1. Select any TIG procedure.
2. Press the key U and while holding it down, press the
key H. Hold both keys down until the display T reads
H2O.
3. Select the working mode with the knob Q
1 = Unit off,
2 = Continuous operation,
3 = Automatic operation.
To exit the selection menu briefly press U.
N.B. "Automatic operation" means that the cooling unit is
started when the torch button is pressed and stopped after
approximately 2 minutes from releasing the torch button.
Caution! If electrode welding is selected, cooling is not
active and cannot be selected. Upon machine power-on, the
display T may show the flashing message H2O.
3.6. SAVING
You may save parameters only after welding.
Pressing the push-button U 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. Saving data from the PL program
Using the machine for the first time
When the machine is turned on, the display shows the
symbol PL; this disappears after 5 seconds, and a working
current is displayed. Follow the instructions in paragraphs
3.2 and 3.5, then proceed as follows to save the data in the
program P01:
• Briefly press the push-button U the message P01 will
appear flashing.
• Press push-button U for more than 3 seconds, until the
symbol P01 stops flashing: at this point, the data have been
saved.
• Obviously, if you wish to save in a program other than P01,
