3.1
COOLING UNIT. (OPTIONAL).
This cooling unit was designed to cool the welding torches
used for MIG/MAG welding. It must be used exclusively with
this power source.
3.2 DESCRIPTION OF PROTECTIVE DEVICES.
3.2.1 COOLANT PRESSURE PROTECTIVE DEVICE.
This protection is achieved by means of a pressure switch,
inserted in the fluid delivery circuit, which controls
a microswitch. Low pressure is indicated by the abbreviation
H2O flashing on the display AM.
3.2.2 FUSE (T 2A/250V - Ø 5X20).
This fuse is inserted to protect the motor pump, and is lo-
cated on the rear panel of the welding machine H.
3.2.3 POSITIONINNG ON SLOPING PLANES.
Since this welding machine is equipped with wheels with-
out brake, make sure the machine is not positioned on slop-
ing planes, to avoid tilting or noncontrolled motion of the
machine itself.

(FIG. 2)
AE selection key.
Each brief pressure selects the size, adjustable via the AI
knob. The sizes which can be selected are shown by LEDs
AA/AB/AC/AD.
LED AA PRG.
Indicates that the display AL shows the set program num-
ber.
LED AB Thickness.
The AL display shows the recommended thickness based on
the set current and wire speed. Active only in synergic MIG
processes.
LED AC Wire speed.
Indicates that the display AL shows the wire speed in weld-
ing.
LED AD Current.
Indicates that the display AL shows a welding current. Dur-
ing welding always shows the measured current; with the
machine at a standstill, if AG is OFF, shows the set current.
LED AF - Globular position.
May not be selected. Active in synergic MIG process. When lit,
this signals that the pair of values chosen for welding may
give unstable arcs and splatters.
