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, practical advice or
simple 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.
IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE
FROM QUALIFIED PERSONNEL.
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.
2.2 EXPLANATION
SPECIFICATIONS LISTED ON THE MACHINE PLATE.
N° Serial number, which must be indicated on any
type of request regarding the welding machine.
Single-phase
frequency converter.
Drooping-characteristic.
MMA Suitable for welding with covered electrodes.
TIG Suitable for TIG welding.
U0 Secondary open-circuit voltage
X Duty cycle percentage. % of 10 minutes during
which the welding machine may run at a certain
current without overheating.
I2. Welding current
U2. Secondary voltage with current I2
U1. Rated supply voltage
1- 50/60Hz 50- or 60-Hz single-phase power supply
I1 max. This is the maximum value of the absorbed
current.
I1 eff. This is the maximum value of the actual current
absorbed, considering the duty cycle.
IP23C Protection grade of the housing, approving the
equipment as suitable for use outdoors in the
rain.
C: The additional letter C means that the
equipment is protected against access to the live
parts of the power circuit by a tool (diameter 2,5
mm).
OF THE TECHNICAL
static transformer-rectifier
Suitable for hazardous environments.
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 U 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 stop of the machine is indicated by the flashing of the
red LED S and signals:
1) During the start-up phase, the power status of the
machine.
2) After the start-up phase, incorrect supply voltage.
3) With the machine running, that the voltage has fallen
below 118V.
4) With the machine running, that the supply voltage is
above 300V.
5) During welding, that the voltage exceeds 300V. To
restore operation, check the voltage. Then shut off
the B1 switch, wait 5 seconds, and switch it on again.
If the problem has been corrected, the welding
machine will begin operating again.
6) During TIG welding, that the secondary open-circuit
voltage exceeds 63 Vrms.
NOTE: if the supply voltage is below 170V at start-up,
no LED will light and the fan is powered.
If the message E2 appears on the display, the
machine requires technical intervention.
2.3.3 Motor-driven generators
They must have an electronic regulator of the tension, a
power equal to or greater than 7 kVA single-phase, and
must not deliver a voltage greater than 260V.

3. INSTALLATION

Make sure that the supply voltage matches the voltage
indicated on the specification plate of the welding
machine.
The capacity of the overload cut-out switch or fuses
installed in series with the power supply must be
equivalent to the absorbed current I1 of the machine.
WARNING! Extension cords of up to 30m must have a
cross-section of at least 2.5 mm2.
3.1 START-UP
Only skilled personnel should install the machine. All
connections must be carried out according to current
standards and regulations, and in full observance of
safety laws (CEI 26-10 -CENELEC HD 427).
