9. MAINTENANCE
1. A great care should be taken to the cutting torch. The molten material
sprays while cutting. This sputter contaminates the interior space of the
torch. The worn parts (consumables) of a plasma torch should be regularly
maintained and timely exchanged. Regularly check the condition of
diffuser channels (see diagram of the torch). If contaminated, you must
clean it with a pressure air or to replace the diffuser. Poor state of the
diffuser has a negative impact on the quality of cutting and causes very
strong interference that may cause the collapse of the machine control
electronics or influence the surrounding devices. If the cable bundle of the
torch is worn out it must be replaced immediately - danger of electrical
shock.
2. Disconnect the HOMER from the mains supply voltage before
disassembling.
3. Special maintenance is not necessary for the control unit parts in the
plasma cut machine. If these parts are damaged for any reason,
replacement is recommended.
CAUTION
4. Do not blow air into the plasma cut during cleaning. Blowing air into the
plasma cut can cause metal particles to interfere with sensitive electronic
components and cause damage to the welder.
5. To clean the plasma cut, disconnect it from the mains supply voltage then
open the enclosure and use a vacuum cleaner to remove any accumulated
dirt and dust. The plasma cut should also be wiped clean. If necessary,
solvents that are recommended for cleaning electrical apparatus may be
used.
6. Troubleshooting and repairing of HOMER equipment should only be
carried out only by suitably qualified or competent person.
7. A ‘competent person’ must be a person who has acquired through training,
qualification or experience, or a combination of them, the knowledge and
