Operation Disturbances; Maintenance - Kemppi KEMPOWELD 3200 Operation Instructions Manual

3. OPERATION DISTURBANCES

By the operation or functional disturbances take the measures according to the following list.
If the disturbance cannot be eliminated, check the equipment according to the paragraphs Installation and
Maintenance, and take contact with Authorized Kemppi repair workshop.
The pump does not get started by test switch:
– check the fuse on the front plate of the cooling unit
– check the fuse on the rear plate of the power source
– check position for cooling mode selecting switch
– check positions for main switches
The water does not circulate by lever switch:
– check the tank filling volume
– disconnect the connector for the return water hose of the gun from the rear wall of the cooling unit and use
thet test switch
If the water is pumped, close the connector and run again by the test switch
A good tip: Blow compressed air into the tank; closing the filling opening by hand is enough.
The water is pumping, but does not return back to the tank or the return flow is weak:
– filling of interconnection cable can take several minutes
– if you have lifted the gun or interconnection cable for the filling time many meters higher than the power
source, the filling will happen considerably slower. Fill the hoses on the floor position.
– check the whole flowing line connector by connector
The water is pumping, but during welding the red pilot lamp for the water pressure is lit and
the equipment is stopped:
– check the cooling water volume and return flow to the tank
– in the system are air bubbles or leakages, especially check the connections of the cooling unit.
– the pressure switch set value (ca. 1 bar) is unsuitable for the gun you are using:
1. Open the side plate. In the middle at the upper end of the pressure guard connected to the pump is the
adjusting screw for limit value.
2. Use the pump during the adjustment by the test switch.
3. After ca. 5 s use twist the screw carefully until the pilot lamp is switched off.
4. Check the result by welding.
5. If the adjustment and checkings do not eliminate the disturbance, take contact with the Authorized Kemppi
repair workshop.
During welding the yellow pilot lamp for overheating is lit and the equipment is stopped:
– release the trigger. When the lamp is switched off, the operation has been reset automatically
– check if the gun is suitable for power you are using
– check condition of connectors and connections in the welding current circuit

4. MAINTENANCE

The amount of use and the working environment should be taken into consideration when planning the frequency of
maintenance of the machine. Careful use and preventive maintenance will help to ensure trouble-free operation.
Cables
Check the condition of welding and connection cables daily. Do not use faulty cables! Make sure that the mains
connection cables in use are safe and according to regulations! The repair and mounting of mains connection cables
should be carried out only by an authorized electrician.
Power source
