GENERAL NOTES

Before using this welding machine, carefully read the stan-
dards CEI 26-23 / IEC-TS 62081. Also make sure the insula-
tion 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)
- Make sure that the switch AF is in position 0, then connect
the welding cables, observing the polarity required by the
manufacturer of the electrodes you will be using; also con-
nect the clamp 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 clamp simultaneou-
sly with the earth clamp.
- Turn the machine on using the switch AF.
- Select the MMA procedure by pressing the button A:
LED B 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.

TIG WELDING

By selecting TIG AC welding mode
aluminium, aluminium alloys, brass and magnesium, while
selecting TIG DC
iron and copper.
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 nega-
tive pole (-) of the welding machine.
Connect the torch connector to the welding machine con-
nector AE.
Connect the torch gas hose fitting to the fitting AD on the
machine, and the gas hose from the cylinder pressure regu-
lator to the gas fitting AG on the rear panel.
Turn on the machine.
Do not touch live parts and output terminals while the machi-
ne is powered.

The first time the machine is turned on, select the process
and mode using the push-buttons A and E, and the welding
parameters by means of the key P and the knob AA as
described in paragraph 3.2.
The type and diameter of the electrode to be used must be
selected according to table A:
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-
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.
Use D.I.N. 10 protective glasses for up to 75A, and D.I.N. 11
from 75A up.
3.5.1 Cooling unit (Art. 1341).
If using a water-cooled torch, use the cooling unit.
3.5.1.1 Description of protections
- Coolant pressure protection
This protection is achieved by means of a pressure swit-
ch, inserted in the fluid delivery circuit, which controls a
microswitch.
Low pressure is indicated by the H2O code blinking on
the display Z.
3.51.2 Installation
Unscrew the cap and fill the tank (the equipment is supplied
with approximately one liter of fluid).
It is important to periodically check, through the slot, that the
fluid remains at the "max" level.
As a coolant, use water (preferably deionized) mixed with
alcohol in percentages defined according to the following table:
temperature
0°C up to -5°C
-5°C up to -10°C
NOTE If the pump turns with no coolant present, you must
remove all air from the tubes.
If so, turn off the power source, disconnect the torche hoses,
fill the tank, connect a hose to the fitting (
Insert the pressure switch connector and
the power cord into the sockets AI and AH.
Before starting the power source, turn on the cooling unit. If
the cooling unit has inadvertently not been switched on, the
power source display will flash the message "H2O" and the
power source will not work. To reset it, simply shut off the
