How to lift up the
system
Strap the system safely and securely in
the slings working from the bottom,
then lift up from the ground.
The wire-feeder has a handle and a
hook so that it can be hung up.
NOTE: The lifting and transporting
devices conform with European regula-
tions. Do not use other equipment to lift
or transport the feeder.
Assembling the
welding machine
The standard composition of this weld-
ing installation consists of:
• SMARTMIG T21 Generator;
• MIG-MAG torch; 3 m long;
• Ground lead integrated with the
machine; 3 m long;
The standard equipment also includes
back and front wheels of various sizes
and a chain for conveniently securing
the gas cylinder to the bottle trolley.
Perform the following operations before
using the machine:
• Remove the welding generator and all relative accessories
and components from the packaging;
• Check that the welding apparatus is in good condition, oth-
erwise immediately inform the retailer or distributor;
• Check that all ventilation grilles are open and that no objects
obstruct the free passage of air;
• Attach the wheels and the chain and then attach the torch to
the Euro connection on the rack panel of the machine, fol-
lowing the instructions indicated in fig. A.
Installation
Select the location of the machine to ensure satisfactory and
reliable service. Before installing the welding set the user must
take into account possible electromagnetic problems of the
working area. In particular, we suggest installing the equipment
away from:
• signalling, control and telephone cables;
• radiotelevision transmitters and receivers;
• computers or controlling and measuring instrument;
• safety and protection devices.
The welder must not be rested on a slant of more than 10°.
These welding machines are cooled through air forced-circula-
tion. That is why they must be disposed to facilitate the suction
and the emission of air through the slots of the frame.
The welding unit is characterized by the following classes:
• IP 23 protection class indicates that the generator can be
used in both interior and exterior environments;
• The "S" usage class indicates that the generator can be
employed in environments with a high risk of electrical
shocks.
Connection to the electrical supply
Connection of the machine to the user line (electrical cur-
rent) must be performed by qualified personnel.
All connections must be made in conformity with existing regu-
lations while fully respecting the accident-prevention laws (see
CEI 26-10 CENELEC HD 427 regulations).
Before connecting the cutting equipment to the mains
supply, check that the data on the machine plate corre-
spond to the supply voltage and frequency and its main
switch is on the "0" position.
Fig. A
These welders can work
at different voltages and
are normally supplied to
work at the highest volt-
age shown on the data
plate. Check that this
voltage corresponds to
the mains supply. If not,
remove the cover and
connect up the corre-
sponding red or blue
wire, according to the
mains voltage, as indi-
cated in fig. B. Connec-
tion to the mains supply
must be carried out using
a four-core wire supplied
with the welder, of which:
• three wires must be
connected to the mains
supply.
• the fourth one, YELLOW-GREEN, to EARTH.
Connect a suitable plug (3p+t) to the primary cable and fix
to a socket fitted with fuses or automatic switch; the
proper earth terminal must be connected to the earth con-
nector (yellow-green) of the main supply.
