Usage limits (IEC 60974-2)
The cooling module is sized for cooling by means of water cir-
culation in the torch head in a continuous manner. As a work
cycle, it is considered at 100%.
Installation
WARNING: The cooling device may only be installed horizon-
tally.
The installation site for the system must be carefully chosen in
order to ensure its satisfactory and safe use.
The user is responsible for the installation and use of the sys-
tem in accordance with the producer’s instructions contained
in this manual.
Before installing the system the user must take into consider-
ation the potential electromagnetic problems in the work area.
In particular, we suggest that you should avoid installing the
system close to:
•
Signalling, control and telephone cables.
•
Radio and television transmitters and receivers.
•
Computer and control and measurement instruments.
•
Security and protection instruments.
Persons fitted with pace makers, hearing aids and similar
equipment must consult their doctor before going near a ma-
chine in operation. The installation environment of the device
has to be in conformance with the protection degree of the
housing, which is equivalent to IP 23 (publication IEC 60529),
which means that the device may be used in closed environ-
ments as well as outdoors. This system is cooled by means of
the forced circulation of air, and must therefore be placed in
such a way that the air may be easily sucked in and expelled
through the apertures made in the frame.
Usage norms
CONTROL APPARATUS (Fig. A)
Pos. 1
Red snap-in connector for water intake.
Pos. 2
Blue snap-in connector for water outlet.
Pos. 3
Cap with microvalve for filling of the tank with coolant.
Pos. 4
Cable for electric connection of the device to the gen-
erator cooling connector.
Pos. 5
Level indicator for presence of coolant in the tank (the
level of the liquid must never be inferior to the notch
indicated).
Pos. 6
Protection fuse.
Electrical wiring of the welding cooling
device and successive mechanical
coupling
The cooling device is not designed as a stand-alone system
and therefore it must be connected electrically, in order to op-
erate, to the welding power source, making the coupling be-
tween the 3x2 pole male connector in the cooling devise (Pos.
4, fig. A) and the corresponding female on the welding power
source (to ignite the female connector just remove its specific
covering (Fig. B) located under the base of the machine) fol-
lowing the assembly instructions attached.
Prior to beginning, the operator has to assure that close at
hand there is both the welding power source (example: DIX TIG
1906.M HF) and the cooling device (example: DIX CM 141.M)
and that both are working at the same supply voltage (see the
two data panels positioned under the respective bases).
Upon final connection, even the pressure switch will be con-
nected. The pressure switch has a protective function. It does
not allow the welding power source to emit voltage in case the
water pressure and therefore the cooling capacity, is inferior
to the calibration value.
Having terminated the electrical connections, complete the me-
chanical coupling by means of screws and fastening clamps.
