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 PEGAS from the mains supply voltage before
disassembling.
3. Maintaining the pneumatic system consists of regular draining of the
condensate traps, at least once a day. Furthermore, visually check the level
of pollution of the air filter and if necessary, disassemble and cleaned the
filter.
4. Setting the operating pressure - while cutting the pressure must not fall
below 0.35 MPa. Setpoint is carried out by the control head on the pressure
regulator. Head must first be unlocked by pulling upward, to set the desired
pressure and pushing again downwards to secure. If the machine does not
consume any air, a slight increase in pressure (about 0,05MPa) appears. It
is therefore necessary to check the pressure during cutting.
5. The power generator must be periodically cleaned by compressed air
(according to the degree of dust inside the generator).
NOTE: Beware of the risk of damage to the electronic components by direct
action of compressed air from a small distance.
6. Troubleshooting and repairing of PEGAS 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
