COOLING UNIT FEATURES
This cooling unit designed for use on MIG/MAG and TIG welding torches,
can only be used inside arc welding sources speci cally assembled for
this purpose.
TECHNICAL SPECIFICATIONS
Rating plate (TAB. 1)
The main information on the use and performance of the cooling unit is
summarised on the rating plate and has the following meanings:
1- P l/min: cooling power at 1 l/min ow of cooling liquid and an
1
ambient temperature of 25°C.
2- Symbol of cooling system with coolant.
3- Symbol of the main power supply.
4- U
: Alternating voltage and power supply frequency to the cooling
1
unit (allowed limits ± 10%).
5- Symbols referring to safety standards: read the instruction manual
carefully before using the device!
6- Serial number to identify the cooling unit (essential for technical
assistance, spare part requests, tracing of product origin).
7- EUROPEAN standard of reference for safety and for construction of
cooling systems for arc welding machines.
8- I
max: maximum current absorbed from the mains.
1
9- Protection ratings of the casing.
10- Pmax: maximum pressure.
NOTE: The rating plate shown is an example to explain the meanings of
the symbols and gures; the exact technical speci cations for the cooling
unit should be taken directly from the rating plate on the machine itself.
INSTALLATION, SAFETY AND OPERATING INSTRUCTIONS
ATTENTION! DIRECT CONNECTION OF THIS DEVICE TO THE
MAINS NETWORK AND/OR USE AS A STAND-ALONE UNIT IS STRICTLY
PROHIBITED.
ATTENTION! THE WELDING MACHINE MUST BE TURNED
OFF AND DISCONNECTED FROM THE MAINS BEFORE COMMENCING
ANY INSTALLATION AND POWER CONNECTION OPERATIONS.
THE ELECTRICAL CONNECTIONS MUST ONLY BE CARRIED OUT BY
EXPERT OR QUALIFIED TECHNICIANS.
HOW TO LIFT THE MACHINE
The cooling unit described in this manual does not have any speci c
lifting devices.
CONNECTION TO THE WELDING MACHINE
1- Remove the packaging from the cooling unit (G.R.A.).
2- Remove the left lower side panel of the welding machine to access
the G.R.A. housing compartment Fig. A.
3- Remove the closure cap on the access area to the cooling liquid on
the front of the welding machine Fig. B1 (version with integrated wire
feeder only). Remove the closure on the rear of the welding machine
(version with separate wire feeder only).
4- Open the closure hatch on the access area to the tank nozzle on the
front of the welding machine (the closure hatch can be replaced in its
seat when the G.R.A. installation operations have been completed)
Fig. B2.
5- Unscrew and remove the tank cap on the G.R.A. Fig. B3.

6- Search for the power connector arriving from the upper section of
the welding machine compartment Fig. C1, which will be coupled
with the connector on the G.R.A. Fig. C2.
7- Insert the G.R.A. in the compartment, positioning the tank nozzle
towards the front of the welding machine so the power connectors
can be coupled together Fig. D.
8- Then, complete insertion of the G.R.A. in the welding machine
compartment, moving it completely to the front (version with
integrated wire feeder only) or the rear (version with separate wire
feeder only). Fix the G.R.A. in place using the screws and washers
provided Fig. E.
9- Before completely closing the side panel Fig. F, it is necessary to run
the G.R.A. start "OPERATING PROCEDURE".
The "FIRST G.R.A. START-UP" may require access to the bleeder valve Fig.
E1.
OPERATING INSTRUCTIONS
ATTENTION! THE TANK FILLING OPERATIONS SHOULD
ALWAYS BE PERFORMED WITH THE MACHINE SWITCHED OFF AND
DISCONNECTED FROM THE MAINS SUPPLY.
ONLY USE THE COOLANT RECOMMENDED BY THE MANUFACTURER
OF THE COOLING UNIT.
NEVER USE POLYPROPYLENE BASED ANTIFREEZE LIQUIDS.
1- Use the nozzle to ll up the tank: Tank CAPACITY = 4l; do not over ll
it to prevent any liquid over owing.
2- Close the tank cap.
3- Connect the external cooling tubes to the relative couplings
paying attention to the instructions below:
: COOLANT DELIVERY (Cold - blue coupling element)
: COOLANT RETURN (Hot - red coupling element)
4- Start the welding machine following the instructions contained in
the machine's Instructions Manual.
The cooling unit operations may di er depending on the type of welding
machine being used. Some applications require the G.R.A. to be started at
exactly the same time as the welding machine, while in others the G.R.A.
starts automatically when welding operations commence.
FIRST G.R.A. START-UP
During rst start-up, it is usually necessary to bleed the air present in the
G.R.A. circuit in order to start the coolant circulation.
So, if an insu cient coolant pressure alarm is triggered and visible on the
welding machine control panel, proceed as follows:
- Reset the welding machine which allows the G.R.A. to be restarted;
- Unscrew the bleeder valve immediately by hand Fig. E1;
- Keep it open for a few seconds to allow the coolant to circulate
properly;
- Retighten the valve to prevent any subsequent coolant leaks;
- When the G.R.A. is up and running, close the welding machine side
panel Fig. F.
If the circulation does not start and the alarm is triggered again, turn o
the welding machine immediately and refer to the maintenance section
for further instructions.
NOTE:
- After running the unit for a few minutes, especially if exible connection
extension hoses are being used, it may be necessary to top-up the tank
level with a suitable amount of liquid.
- On switching o the welding machine, the G.R.A. may continue to run
for from 3 to 10 minutes.
MAINTENANCE
ATTENTION! BEFORE CARRYING OUT MAINTENANCE
WORK, MAKE SURE THAT THE WELDING MACHINE IS SWITCHED OFF
