1. PREFACE

1.1. INTROdUCTION

Congratulations on having purchased this product. Properly installed Kemppi products should

prove to be productive machines requiring maintenance at only regular intervals. This manual is

arranged to give you a good understanding of the equipment and its safe operation. It also contains

maintenance information and technical specications. Read this manual from front to back before

installing, operating or maintaining the equipment for the rst time. For further information on

Kemppi products please contact us or your nearest Kemppi distributor.

The specications and designs presented in this manual are subject to change without prior

notice.

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

KWU10 is a cooling unit designed to be connected to the Kemppi WeldForce welding machine

and used for cooling the welding gun. The operation of KWU10 is controlled by a microprocessor.

KWU10 is delivered equipped with a plastic funnel for relling the water.

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 has not been 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cation of 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.

2.4. INSTALLATION ANd MAIN PARTS

2.4.1. Assembling the equipment

The equipment is assembled in the following order:

1. Transport unit T400 6185267

Transport unit P40/P40L 6185264/6185264L

2. KWU10 cooling unit 6262110

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.

2.4.2. Main parts of cooling unit

This equipment’s electromagnetic compatibility (EMC) is designed for use in an

industrial environment. ClassA equipment is not intended for use in residential location

where the electrical power is provided by the public low-voltage supply system.

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 40 - 20 % mixture of glycol and water, or with any other suitable

antifreeze agent. The capacity of the reservoir is 3 litres.

4. Connect the mains voltage and control connectors of the cooler unit to the corresponding

connectors on the base of the power supply. The connection can be established through the

base of the power supply when the devices are separated or through the right side of the

KWU10 cooler by removing the right side plate.

5. Attach the power supply on the KWU10 cooler.

6. Switch on the power supply.

7. Press and hold down the test switch until the torch hoses are lled with liquid. The text

ERROR will remain on the KWF wire feeder panel as long as the gun hoses contain air.

8. Device is ready to weld.

3. OPERATION

3.1. COOLER OPERATION

See also 2.4.2. Main parts of cooling unit

KWU10 cooler operation is controlled by the microprocessor of the power supply. The cooler pump

starts to operate when the welding begins. After the welding has stopped, the pump will operate

1 to 5 minutes longer depending on the welding time. During this time the liquid will cool down

to the surrounding temperature. If the pump is stopped, the need for maintenance of the cooler

will be reduced.

Check the tank liquid level regularly and ll in liquid, if necessary.

When the system loses pressure, e.g., the reservoir is empty or one of the hoses leaks, the display

will show ’Error’ and welding will be interrupted.

3.2. 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.

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 utilisation 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 operations 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

6 – KWU10 / 0613 © Kemppi oy

4.2. EvERy SIXTh MONThS

The following maintenance operations 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.

• Check seals, cables and connections. Tighten, if necessary and replace defect parts.

4.3. TROUbLE ShOOTING

See also 3.2. Overheat signal lamp.

Overheat signal lamp is lit.

The unit is overheated.

• Check water circulation.

• Check that there is enough free space behind the machine for cooling air circulation.

Text ERROR 5 on the KWF wire feeder panel

• Check the liquid hoses for damages.

• Remove any hose blockages.

• Check water circulation, clean the ventilation grilles and add liquid if needed.

For further information and assistance, contact your nearest Kemppi service workshop.
