Read the warning texts carefully and follow the instructions. Please also study the Operation safety
instructions and respect them when installing, operating and servicing the machine.
1.2. PROdUCT INTROdUCTION
Procool is a cooling unit designed for Kemppi Pro -welding equipment and to be used for cooling
welding gun or torch. The operation of Procool is controlled by a microprocessor.
1.3. OPERATION SAFETy
Please study these Operation safety instructions and respect them when installing, operating and
servicing the machine.
Welding arc and spatters
Welding arc hurts unprotected eyes. Be careful also with reecting arc ash. Welding arc and
spatter burn unprotected skin. Use safety gloves and protective clothing.
Danger for re or explosion
Pay attention to re safety regulations. Remove ammable or explosive materials from welding
place. Always reserve sufcient re-ghting equipment on welding place. Be prepared for hazards
in special welding jobs, eg. for the danger of re or explosion when welding container type work
pieces. Note! Fire can break out from sparks even several hours after the welding work has been
nished!
Mains voltage
Never take welding machine inside a work piece (eg. container or truck). Do not place welding
machine on a wet surface. Always check cables before operating the machine. Change defect cables
without delay. Defect cables may cause an injury or set out a re. Connection cable must not be
compressed, it must not touch sharp edges or hot work pieces.
Welding power circuit
Isolate yourself by using proper protective clothing, do not wear wet clothing. Never work on a
wet surface or use defect cables. Do not put MIG-gun or welding cables on welding machine or
on other electric equipment. Do not press MIG-gun switch, if the gun is not directed towards a
work piece.
Welding fumes
Take care that there is sufcient ventilation during welding. Take special safety precautions when
welding metals which contain lead, cadmium, zinc, mercury or beryllium.

2. INSTALLATION
2.1. REMOvAL FROM PACkAGING
The equipment is packed in durable packages specially designed for them. Check the equipment
before taking it into use, to make sure that the equipment or a part of it have not got damaged
during the transportation. Also check that the delivery corresponds your order and that you have
received all the necessary instructions for installing and operating the equipment. The packaging
material can be recycled.
2.2. LOCATING ThE MAChINE
Place the machine on a horizontal, stable and clean ground. Protect the machine from heavy rain
and burning sunshine. Check that there is enough space for cooling air circulation in front of and
behind the machine.
2.3. SERIAL NUMbER
The serial number of the machine is marked on the machine CE-marking. Identicating
the serial number is the only proper means of maintaining and identifying parts for a specic
product. It is important to make correct reference to the serial number of the product when making
repairs or ordering spare parts.
2.4. INSTALLATION ANd MAIN PARTS
2.4.1. Assembling the equipment
The equipment is assembled in the following order:
1. Transport unit P40/P40L 6185264/6185264L
2. Cooling unit Procool 20 6262014NX
Assembly the transport unit according to the instructions in the package. Fasten the cooling unit
to the transport unit by using the screws and bolts delivered with the equipment.

2.5. PREPARING FOR OPERATION
Cooling liquid is injurious! Avoid also contact with skin or eyes. In case of injury,
seek for medical advice.
See also 2.4.2. Main parts of cooling unit.
1. Install the cooling unit control cable into the wire feed unit.
2. Connect the cooling water hoses with the wire feed unit, follow colour markings.
3. Fill the reservoir with a 20 - 40 % mixture of etanol and water, or with any other suitable
antifreeze agent. The capacity of the reservoir is 3 litres.
4. Install the mains cable plug to the earthed socket of power source.
3. OPERATION
3.1. COOLING UNIT OPERATION
See also 2.4.2. Main parts of cooling unit.
The operation of Procool is controlled by a microprocessor. The cooling unit pump starts
automatically when welding starts. The pump operates still for 5 minutes after welding has been
nished, to cool the water to the same temperature as in the machine surround. This reduces the
need of service. Proceed as follows:
1. Start power source and cooling unit.
2. Press the test switch until the red control light goes out.
3. The water is now circulating and you can start welding.
Check water level and input ow regulary, add liquid if needed.
3.2. COOLING UNIT PILOT LIGhTS
The control lamp is lighting always when the machine is connected to mains voltage and the main
switch is in position I.
Overheat signal lamp
The overheat signal lamp is lighting when temperature control of the machine has detected cooling
water overheat. The ventilator cools down the machine and when the lamp goes out welding can
be started again.
Water ow signal lamp
The red signal lamp is lighting when water ow is blocked.
3.3. STORAGE
The machine must be stored in a clean and dry room. Protect the machine from rain and keep it
away from direct sunshine in places where temperature exceeds +25 °C. Check that there is free
space in front of and behind the machine for air circulation.

4. MAINTENANCE
Watch out for mains voltage when handling electric cables!
In planning product maintenance machine utilization degree and circumstances should be considered.
Careful use and preventive maintenance help to avoid unnecessary production disturbances and
breaks.
4.1. dAILy MAINTENANCE
The following maintenance opeations should be carried out daily:
– Check water level and input ow, add liquid if needed.
– Check cables and connections. Tighten, if necessary and replace defect parts.
4.2. EvERy SIXTh MONThS
The following maintenance opeations should be carried out at least every sixth months:
– Clean off dust and dirt. Change the cooling liquid and wash up the pipes and water reservoir
with pure water.
