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. P1 1/min: cooling power at a refrigerant flow rate of 1 l/min and an ambient temperature of 25°C.
2. symbol for system with liquid refrigerant.
3. symbol for main power supply.
4. U1: Alternating voltage and frequency of cooling unit 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. I1 max: maximum current absorbed by the line.
9. Protection rating of enclosure.
10. Pmax: maximum pressure.

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! ALL THE INSTALLATION OPERATIONS AND ELECTRIC CONNECTIONS SHOULD BE CARRIED OUT WITH THE EQUIPMENT TURNED OFF AND DISCONNECTED FROM THE POWER SUPPLY. EXPERT AND QUALIFIED PERSONNEL MUST CARRY OUT THE ELECTRIC CONNECTIONS.

LIFTING THE EQUIPMENT
The cooling unit described in this manual is not fitted with lifting systems.

POSITIONING THE EQUIPMENT
The installation position for the cooling unit must be 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 supplied (Fig. A).

CONNECTION TO THE WELDING MACHINE

• Connect the supplied cable to the cooling unit (FIG. A), using the relative coupling (female 5-pole).
• Connect the coupling (male 5-pole), on the other end of the cable, to the corresponding socket on the rear panel of the welding machine.

OPERATION

WARNING! THE TANK FILLING OPERATIONS SHOULD ALWAYS BE PERFORMED WITH THE MACHINE SWITCHED OFF AND DISCONNECTED FROM THE MAIN SUPPLY. ONLY USE THE COOLANT RECOMMENDED BY THE MANUFACTURER OF THE COOLING UNIT.
NEVER USE POLYPROPYLENE-BASED ANTIFREEZE LIQUIDS.

1. Use the nozzle to fill up the tank: Tank CAPACITY = 4 l; do not overfill it to prevent any liquid from overflowing.
2. Close the tank cap.
3. Connect the external cooling tubes to the relative couplings paying attention to the instructions below:
4. Connect the cooling unit to the welding machine using the specific cable supplied.
5. There are no switches or signalling devices on the cooling unit because the cooling unit control is managed by the welding machine. The cooling unit operations may differ depending on the type of welding machine connected. There are applications in which the startup of the unit takes place at the same time as the welding machine starts and others, where the cooling unit starts to work automatically starting from the instant welding, begins; when welding stops, the unit can stay on for a time of between 3 and 10 minutes based on the intensity of the current used. Circuit pressure control, i.e. liquid circulation, is conducted by the welding machine: if there is an insufficient liquid pressure signal, welding is commanded to STOP and an alarm is simultaneously displayed on the control panel display of the welding machine.
6. After running the unit for a few minutes, especially if flexible connection extension hoses are being used, it may be necessary to top-up the tank level with a suitable amount of liquid.
7. If the control panel of the welding machine displays an alarm relating to the cooling unit, it may be necessary to eliminate the air in the circuit to enable liquid circulation. With the unit on, manually unscrew the bleeder valve (Fig. B) for a few seconds to stimulate the start of liquid circulation, and then re-start the valve to avoid leaking liquid.
8. Another possible cause of alarm relating to the cooling unit is overheating of the coolant liquid. In this case, you should operate the welding machine with no load for a few minutes, until the fan of the cooling unit brings the temperature of the liquid within the correct values.
9. To clear a cooling alarm, once the cause has been eliminated, you may need to switch the welding machine off and back on. If circulation does not start and the welding machine continues to indicate a cooling alarm, immediately switch off the cooling unit and refer, for first intervention, to the maintenance section.
10. Do not operate the unit if the torch tubing is not connected.

MAINTENANCE

ATTENTION! BEFORE CARRYING OUT MAINTENANCE WORK, MAKE SURE THE COOLING UNIT IS SWITCHED OFF AND DISCONNECTED FROM THE POWER SUPPLY.
If checks are carried out while the inside of the cooling unit is live, this could cause a serious electric shock due to direct contact with live parts and/or injury due to direct contact with moving parts.

ROUTINE MAINTENANCE
ROUTINE MAINTENANCE WORK CAN BE PERFORMED BY THE OPERATOR.

• Check the level of liquid in the tank regularly, according to the degree of use.
• Check regularly that the external flexible hoses connected to the cooling unit are not obstructed.
• Change the coolant every 6 months.

EXTRAORDINARY MAINTENANCE
EXTRAORDINARY MAINTENANCE OPERATIONS SHOULD BE CARRIED OUT ONLY AND EXCLUSIVELY BY SKILLED OR AUTHORISED ELECTRICAL-MECHANICAL TECHNICIANS.

ATTENTION! SHOULD THE FOLLOWING SITUATIONS OCCUR:

• persistent cooling unit alarm;

• excessive need to top-up the level in the tank;

• liquid leaks; switch off the cooling unit immediately, remove the plug from the power socket and examine the flexible hoses, the coupling elements and the internal and external components on the cooling circuit and make any repairs as necessary.
  ATTENTION! If the tank was emptied and the cause has been detected and resolved, it may be necessary to bleed the air from the circuit to restart the circulation of the coolant in the system. In this case, proceed as follows:

• fill the tank and screw in the closure cap;

• connect the flexible hoses of the cooling unit to the feeder/torch unit;

• start the cooling unit;

• check liquid is circulating and, if this is not the case, manually unscrew the bleeder valve (Fig. B) for a few seconds to eliminate the air in the circuit and re-start circulation;

• close the valve immediately afterwards to avoid liquid leaking.
