6 MAINTENANCE

Regular maintenance is important for safe, reliable operation.

Only those persons who have appropriate electrical knowledge (authorized

personnel) may remove the safety plates.

WARNING

Ensure that the mains voltage supply to the machine has been disconnected

externally. Switch off the switch at the wall socket before inspecting or working in

the power source.

WARNING

Water or oil can collect in the compressed air lines. Always direct the first stream of

air away from the equipment, to prevent damage.

CAUTION

All guarantee undertakings from the supplier cease to apply if the customer himself

attempts any work in the product during the guarantee period in order to rectify any faults.

If the equipment does not work correctly, stop work immediately and determine the

cause of the problem. Maintenance work may only be carried out by persons with

the applicable knowledge. Electrical work may only be carried out by authorised

electricians. Never allow persons other than those with the applicable knowledge to

check, clean or repair the equipment. Only use recommended spare parts.

6.1 Inspection and cleaning

The following points on the power source should be checked and/or cleaned

regularly.

1. Check the return cable connection to the work piece.

2. Check that the protective earth from the work piece is securely connected to the

power source chassis earth.

3. Check the torch heat shield. Replace it if it is damaged.

4. Check the electrode and the nozzle for wear daily. Remove any splash, replace

the electrode and nozzle as necessary. If the electrode has a pit which is more

than 1.5 mm deep at its center, it must be replaced. If the electrode is used

beyond this recommended wear limit, damage to the torch and power source

may occur. Nozzle life is also greatly reduced when using the electrode below

the recommended limit.

5. Check that the cables or hoses are not damaged or bent.

6. Check that all plugs and connections and ground terminals are firmly connected.

7. Ensure that all incoming power supplies are disconnected. Use goggles and face

mask and blow clean the power source internally using dry compressed air at

low pressure .

8. Regularly drain any water from the filter below the air regulators.
