IMPORTANT NOTE:
BEFORE USING THE EQUIPMENT READ THE
INSTRUCTION MANUAL CAREFULLY!
WATER COOLING UNIT FEATURES
This water cooling unit must only be used to cool torches
used on TIG welding systems.
TECHNICAL DATA
Data plate (TAB. 1)
The main data relating to use and performance of the
cooling unit are summarised on the rating plate and have
the following meanings:
1 - P : cooling power at a refrigerant flow rate of 1 l/
1 l/min
min and an ambient temperature of 25°C.
2 - symbol for system with liquid refrigerant.
3 - symbol for main power supply.
4 - U : Alternating voltage and frequency of cooling unit
1
power supply (allowed limits ± 10% ).
5 - symbols referring to safety standards: before
using the apparatus read the instruction handbook
carefully!
6 - serial number for identifying the coolant unit
(essential when asking for servicing or spare parts,
or finding the origin of the product).
7 - EUROPEAN standard of reference for safety and
construction of cooling systems for arc welding.
8 - I : maximum current absorbed by the line.
1 max
9 - Protection rating of enclosure.
10 - P : maximum pressure.
max
NOTE: The rating plate shown is an example to show the
meaning of the symbols and numbers; the exact values of
the technical properties of the cooling unit should be read
directly on the rating plate of the unit itself.
INSTALLATION, SAFETY AND OPERATIONS
WARNING!
OPERATIONS AND ELECTRIC CONNECTIONS
SHOULD BE CARRIED OUT WITH THE
EQUIPMENT TURNED OFF AND DISCONNECTED
FROM THE POWER
QUALIFIED PERSONNEL MUST CARRY OUT THE
ELECTRIC CONNECTIONS.
LIFTING THE EQUIPMENT
The cooling unit described in this manual is not fitted with
lifting systems.

chosen to ensure that the cooling air inlet and outlets are
not blocked in any way (forced fan circulation, if fitted); at
the same time, ensure that no conductive dust, corrosive
vapours, humidity, etc. could be sucked in.
A free space of at least 250 mm should be left around
the cooling unit.
WARNING! Position the equipment on a flat
surface adequate to support the weight, to
avoid it tipping over or making dangerous
movements.
POWER SUPPLY (ELECTRICAL CONNECTION)
The cooling unit must be connected to the welding
machine using the cable provided (Fig. A).
CONNECTION TO THE WELDING MACHINE
- Connect the cable supplied (Fig. A) to the cooling unit,
using the dedicated connector (5-pin female).
- Connect the connector at the other end of the cable
(5-pin male) to the corresponding outlet on the back
panel of the welding machine.
OPERATIONS
ATTENTION! THE TANK CAN ONLY BE
FILLED AFTER HAVING SWITCHED OFF THE
APPARATUS AND DISCONNECTED IT FROM
THE MAINS.
ONLY USE DEMINERALISED WATER.
IF WORKING WITH TEMPERATURES OF BELOW 2 °C,
WE ADVISE USING ANTIFREEZE WITH AN ETHYLENE
BASE, OR A MIXTURE OF DEMINERALISED WATER
AND ETHYLENE GLYCOL.
DO NOT FOR ANY REASON USE POLYPROPYLENE
BASED ANTIFREEZE.
1 - Fill the tank through the filler: tank CAPACITY = 2 l;
take care not to let the water overflow when the tank
is full.
2 - Close the cap on the tank.
3 - Connect the outer piping for the cooling to the
relative fittings, taking care of the following specific
instructions:
-
-
4 - Make the connection to the power outlet and turn the
switch to position "I". The cooling unit will then start
operation, circulating the water in the torch.
AND 5 - If the water cooling unit is connected to the welding
machine, the supply is controlled by the welding
machine itself.
The functioning of the water cooling system may
differ according to the type of welding machine to
which it is connected.
Depending on the type of application in use, the water
cooling unit gets started at the same time when the
welding machine starts, or when the welding starts.
When welding is stopped, the unit may go on
