1.2 PRODUCT INTRODUCTION

The power sources Kempomat 3200 and 4200 are compact MIG welding machines, designed for heavy industrial use. Kempomat 2500 is compact MIG welding machine, designed for repair shops and light and heavy industrial use.

Power source

Supply voltage of the Kempomat 2500 power source is 3~ 230 V/400 V. Supply voltage of the Kempomat 3200 power source is 3~ 230 V/400 V. Welding voltage adjustment is in 10-steps. Adjustment for voltage of power source is in 40-steps.

In Kempomat 4200 product range there are dierent units for mains voltages 3~ 230 and 400 V. The welding voltage adjustment for 230 V power source is made in 32 steps, 400V power source in 56-steps. The Volt/Ampere metering unit MSD 1 (available as accessory) displays voltage or welding current.

Wire feeder unit

The wire feeder unit is a xed unit in the equipment for air-cooled guns. Kempomat 2500 is equipped with 2 wheel wire drive mechanism, Kempomat 3200 and 4200 are equipped with 4 wheel wire drive mechanism. Accessory unit KMW sync is needed for connection and use of push-pull guns.

2. INSTALLATION OF THE POWER SOURCE

2.1 POSITIONING OF THE MACHINE

Place the machine on a rm, dry and level surface. Where possible, do not allow dust or other impurities to enter the machines cooling air ow. Preferably site the machine above oor level; for example on a suitable carriage unit.

Notes for positioning the machine

• The surface inclination should not exceed 15 degrees.

• Ensure the free circulation of the cooling air. There must be at least 20 cm of free space in

front of and behind the machine for cooling air to circulate.

• Protect the machine against heavy rain and direct sunshine.

NOTE! The machine should not be operated in the rain as the protection class of the machine,

IP23S, allows for outside preserving and storage only.

NOTE! Never aim metallic grinding spray/sparks towards the equipment.

2.2 CONNECTION TO THE MAINS SUPPLY

Connection and change of the mains cable and the plug must be carried out only by a

Kempomat 2500, 3200, 4200 / © Kemppi Oy / 1117

competent electrician. Remove for the mounting of the mains cable the left side plate, seen from the front of the power source.

The Kempomat power source is equipped with 5 m supply cable without plug. The mains cable is according to the marking H07RN-F of the norm CENELEC HD22. The mains cable must be changed if it doesn´t meet local regulations.

2.3 MOUNTING OF THE MAINS CABLE

The cable is entered into the machine through the inlet ring on the rear wall of the machine and locked with a cable clamp (05).

The phase conductors of the cable are coupled to connectors L1, L2 and L3. The earth protection coloured green-yellow is coupled to connector marked with earth protection symbol the cable´s protective shield.

In cables of S type there is protective grounding conductor coloured green-yellow.

By delivery from the factory the Kempomat 3200 and 2500 machine has been connected for mains voltage 3~ 400 V. In order to change the mains voltage in the Kempomat 2500/3200 machine, remove the side plate of the machine. Change the connections according to the enclosed diagram. You nd the corresponding wiring diagram on the instruction label, which is under terminal block.

NOTE! The Kempomat 4200 machine has the connection for only one mains voltage!

2.4 WELDING AND RETURN CURRENT CABLES
