2.3 COOLING UNIT
This cooling unit has been designed to cool the torches
used for MIG/MAG welding.
Must be used exclusively with this power source.

2.3.2 DESCRIPTION OF PROTECTIONS
2.3.2.1 Coolant pressure protection
This protection is achieved by means of a pressure
switch, inserted in the fluid delivery circuit, which controls
a microswitch. The message H2O flashes on the display
M to indicate the pressure (control panel instructions).
2.3.2.2 Fuse
This fuse was inserted to protect the pump, and is locat-
ed on the control circuit inside the unit.
2.3.3 DESCRIPTION OF THE COOLING UNIT (Fig. 1)
BX - Slot:
Slot to inspect the coolant fluid level
BW - Cap.
BT - Quick-fitting valves:
Connect the red and blue lines of the wire feeder/machine
connection.

NOTE: Match the hose and socket colours correctly.
2.3.4 INSTALLATION
Unscrew the cap BW and fill the tank (the equipment is
supplied with approximately one liter of fluid). It is impor-
tant to periodically check, through the slot BX, that the
fluid remains at the "max" level. As a coolant, use water
(preferably deionized) mixed with alcohol in percentages
defined according to the following table:
temperature
0°C up to -5°C
-5°C up to -10°C
NOTE If the pump turns with no coolant present, you
must remove all air from the tubes.
If so, turn off the power source, fill the tank, disconnect
the fitting of the power source/wire feeder connection
from the fitting BT(
Start the power source for approximately 10/15 seconds,
then connect the hoses of the power source/wire feeder
connection.

3 DESCRIPTION OF THE PANEL (Fig. 2)
Selection key V. Each time it is pressed briefly,
it selects the value adjustable via the knob I. The
values that may be selected are in relation to the
type of welding process selected and are displayed on
the LEDs A/B/C/D.
LED A Current.
Indicates that the display M shows the preset weld-
ing current or, in combination with the lighting of the
LED F, the actual welding current.
Active in all welding processes.
LED B Wire speed.
Indicates that the display M shows the welding wire
speed. Active in all welding processes.
LED C Thickness.
The display M shows the recommended thickness
based on the current and wire speed set. Active only in
synergic MIG processes.
LED D JOB.
Indicates that the display M shows the program
number set. Active only in MIG processes.
LED E Globular position.
May not be selected. Active in synergic MIG mode.
When lit, it signals that the pair of values selected for
welding may generate unstable arcs and cause spatters.
