INSTRUCTION MANUAL FOR ARC WELDING MACHINES
IMPORTANT: READ THIS MANUAL AND THE "SAFETY
RULES" MANUAL CAREFULLY BEFORE INSTALLING,
USING, OR SERVICING THE WELDING MACHINE,
PAYING SPECIAL ATTENTION TO SAFETY RULES.
CONTACT YOUR DISTRIBUTOR IF YOU DO NOT FULLY
UNDERSTAND THESE INSTRUCTIONS.
1. PRECAUTIONS
This machine must be used for welding only. It must not be
used to defrost pipes.
It is also essential to pay special attention to the "SAFETY
RULES" Manual.
The symbols next to certain paragraphs indicate points
requiring extra attention,
information.
This MANUAL and the "SAFETY RULES" MANUAL must be
stored carefully in a place familiar to everyone involved in
using the machine. They must be consulted whenever doubts
arise and be kept for the entire lifespan of the machine; they
will also be used for ordering replacement parts.
2. GENERAL DESCRIPTIONS
2.1 SPECIFICATIONS
This welding machine is a constant current power source
built using INVERTER technology, designed to weld covered
electrodes (not including cellulosic) and for TIG procedures,
with contact starting and high frequency.

NOTES: the welding machine has also been designed for use in
environments with a pollution rating of 3. (See IEC 664).
2.3 DESCRIPTION OF PROTECTIVE DEVICES
2.3.1 Thermal protection
This machine is protected by a temperature probe, which
prevents the machine from operating if the allowable
temperatures are exceeded. Under these conditions the fan
keeps running and the LED Q lights.
2.3.2 Block protections
This welding machine is equipped with various safety devices
that stop the machine before it can suffer damage.
The welding machine may operate within the following voltage
ranges:
For rated voltage 208/220/230V, from 175 to 270V
For rated voltage 400/440V, from 340 to 490V
Caution: if the supply voltage does not fall between the above
values, no LED will light and the fan is powered.
If the phases are not properly connected, 3 light points will
appear (steadily lit) on the display R when the machine is
started.
If, with the machine on, the voltage falls below 175 V (U1 =
230V) or 340 V (U1 = 400V), the display R will show the
abbreviation E3.
If, with the machine on, the voltage rises above 275 V (U1 =
230V) or 490 V (U1 = 400V), the display R shows the
abbreviation E4.
In this case turn off the machine, restore the proper voltage and
restart. If the problem has been corrected, the welding machine
will begin operating again.
If, with the machine on, the display R shows the message E2 or
E1, check the supply voltage of the machine; if it is correct, the
machine requires technical service.
If a low water level is detected for the cooling unit the
abbreviation H2O flashes on the display R.
If the Password function is activated and you enter a wrong
password when logging in, the message "E72" appears on the R
display.
2.3.3 PASSWORD
This equipment is protected against the use on behalf of
unauthorised personnel through the request, on ignition, of a
password.
To activate the Password function, press the U key and then,
holding it down, press the K key. Hold both keys down until the
message H2O is displayed on display R, then press the U key
once to bring the message PSS to the R display. By means of
the knob T put on 1, confirm by pressing the key U once; when
igniting the machine, the writing PSS will appear on display R
and with knob T insert the password (displayed on display S)
and confirm by holding the U key down.
If the code is incorrect, the generator will block, displaying the
writing ERR 72 and to insert the password again, it is necessary
to switch the generator off and on.
The password code is supplied together with the machine and
cannot be changed.
