In this document, for danger to life or injury the following symbol is used:

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 reecting 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 sufcient 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 sufcient 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. Identicating

the serial number is the only proper means of maintaining and identifying parts for a specic

product. It is important to make correct reference to the serial number of the product when making

repairs or ordering spare parts.

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.
