1 GENERAL DESCRIPTION

1.1 SPECIFICATIONS

This welding machine allows to weld mild steel, stainless
steel and aluminium.
1.2 EXPLANATION OF TECHNICAL SPECIFICATION
Art. ................ Article number that must be stated when
asking for information or servicing related to
this machine.
Three-phase Transformer - Rectifier
................. External characteristics of the unit.
U .................. Secondary no-load voltage.
o
X ................... The duty-cycle expresses the percentage of
10 minutes during which the welding machine
can operate at a determined current level
without overheating:
For instance: X = 60% at I
This means that the welding machine can
weld with a current I
out of 10, i.e. 60%.
I ................... Welding current

frequency.
I ................... Input current at the corresponding welding

IP 21 ............. Grade of protection of the case. Grade 1 as a
second digit means that this unit is not fit for
working in the rain.
................ Fit for working in high-risk areas.
............. Suitable for MIG-MAG welding.
1.3 DESCRIPTION OF PROTECTION
This unit is protected by a normally closed thermostat
placed on the power transformer.
When the thermostat intervenes, the machine stops
welding, while the motor-driven fan continues to work.
Wait a few minutes to allow the generator to cool down.

supply voltage at the
and start-up.
! WARNING: ELECTRIC SHOCK CAN KILL!
! This machine must be installed by skilled personnel.
! Make sure that the input power plug has been
disconnected before inspecting, repairing, or servicing.
! Connect the yellow-green wire to a good electrical
ground.
2.2 SET-UP
! Unpack the machine and place it in a properly
ventilated area, possibly not dusty, making sure that
airflow on the cooling vents is not obstructed.
! WARNING:
overheating and possible damage to internal parts.
! Maintain at least 20 inches (500 mm) of free space on
all sides of the unit.
! Do not place any filtering device over the intake air
vents of this power source. The warranty is void if any
type of filtering device is used.
2.3 START-UP
This unit must be installed by skilled personnel. All fittings
must be in conformity with the existing safety standards.
(See CEI standards 26-10 - CENELEC HD 427).
! Install the components supplied with the welding
machine (fig.3).
! Connect the welding torch (52).
! Use wire feeder rollers with a "U"-shaped groove for
aluminium wires, and with a "V"-shaped groove for
other wires.
! Check that the wire diameter corresponds to that
shown on the drive roll and mount the wire spool.
! Make sure that the wire goes into the groove of the
drive roll (B fig.2).
! Before connecting the power supply cable (30) ensure
2 that mains voltage corresponds to the machine voltage
rated
and that the earth plug is efficient.
! The connection voltage can be changed on the
threephase machine by following the instructions in
figure.
N.B. : To reach the voltage changer, remove the fixed
housing (37).
Important: Before changing voltage make sure that the
machine is no more connected to the mains.
