Do not put metal wires in the air opening.
Do not touch the electrode when it is in contact with the pie-
ce to work on. Never simultaneously touch electrically hot
parts of electrode holders connected to two welders. Avoid
two people working simultaneously at the same machine.
When the welding machine is not being used, pull out the
power supply cable. More than one welding machine wor-
pieces electrically connected, could cause an accumula-
holders or torches that can become dangerous, because
the value reached is twice the prescribed one.
9) Performance of the welding circuit::
- U0: maximum No Load Voltage
- I2/U2: current and voltage corresponding normalized, that can be provided by
the welding machine while welding
- I2min/ I2max: rated minimum/maximum welding current
- U2min/ U2max: minimum/maximum conventional load voltage
- X: duty cycle
- MIN A / V - MAX A / V: indicates the range of welding current to the
10) Characteristic data of supply line:
- U1: AC voltage and frequency supplied to the welding machine
- I1/MAX: Maximum input current
11) Symbol of the power line, possible values are:
1 ~ Single-phase AC voltage,
3 ~ Triple-phase AC voltage
12) Degree of protection
13) Symbol for class II equipment
14) Symbols related to safety
NOTE: the rating plate examples shown highlight the meaning of the symbols
and numbers; the exact values of the technical data of the welding machine
in your possession must be found directly on the rating plate on the product.

yyyy: Incremental number
4) Welding power source symbol for example:
-
plies with their requirements.
6) Welding process symbol for example:
7) Symbol : for supplying power to welding operations carried out in an en-
vironment with increased hazard of electric shock
8) Welding current symbol for example:
Single-phase transformer
Single- or three-phase static frequency convertertransformer
Inverter power source with AC and DC output
Manual metal arc welding with covered electrodes
Tungsten inert-gas welding
cored wire
Direct current
Alternating current, and additionally the rated frequency in
hertz
Direct or alternating current at the same output, and
additionally the rated frequency in hertz.
This symbol means identify possible risks of the user.
When the symbol on left is found, follow carefully the in-
structions to avoid the risk indicated. Warning, this manual
is an integral part of the product and must be kept until the
machine’s destruction. While working, Keep other people
away, especially children. Protect yourself and the others.
ELECTRIC SHOCK CAN KILL
Avoid direct contact with the welding circuit: the noload
voltage supplied by the welding machine can be very dan-
gerous. The electrode or the welding wire, the guide roller
space and all the metal parts that touch the welding wire
are under voltage when the machine is on. A wrong instal-
lation or earthing of the machine is a risk. Electric installa-
tion must be carried out according to the safety rules.
Wear protective clothing such as a heavy shirt, trousers
synthetic material.
Wear dry welding gloves and without holes.
Position the welding machine so it is stable on the work
surface with a maximum 15% slope from the ground. In-
sulate yourself from work and ground using dry insulation.
Make sure the insulation is large enough to cover your en-
tire area of physical contact with work and ground.
Do not use the machine in very damp places. If this is not
possible make sure the switch and the lifesaving line are
If it is raining, disconnect the machine from the main power
supply.
Be sure the working place is provided of a good earthing
plant. Before making any electrical connection, make sure
the rating data of the welding machine correspond to the
mains voltage and frequency available at the place of in-
stallation.
Welding cables connection, maintenance, and repair must
-
sconnect it from the main power supply before replacing
the worn parts of the torch. The main power supply outlet
must be suitable to the device’s plug.
Absolutely avoid modifying the plug.
Do not use damaged cables, of a smaller size than requi-
red or joined incorrectly. Keep cables dry, clean and pro-
tected from hot metal sparks.
-
rent from those prescribed, especially it must not be used
to carry or hang the machine. Do not bring the cable near
heat, oil or sharp edges. Frequently check the cable to de-
tect possible damages or damaged wires. If so, immedia-
tely replace any damaged cable because uncovered wires
can kill.
Do not wrap earth cable, torch cable, power supply cable
around your body.
FUMES AND GAS CAN BE DANGEROUS
Welding may produce fumes and gases hazardous to heal-
th. Avoid breathing these fumes and gases. In order to limit
the production of fumes, before using the machine, clean
the pieces to weld from rust, grease, oil and paint.
still contain a dangerous residual voltage that can be lethal.
