CHAPTER 4. MAINTENANCE OPERATIONS. RECOMMENDATIONS.

In order for the equipment to have a long life we
must follow some essential rules for maintenance
and use. Abide by these recommendations.
CORRECT MAINTENANCE OF THE EQUIPMENT
WILL AVOID A GREAT PERCENTAGE OF FAULTS.
4.1 MACHINE MAINTENANCE. GENERAL
RECOMMENDATIONS.
Before carrying out any operation on the machine
or torch, we must place switch l1 of the equipment
in "O" position of machine disconnected.
Specialized personnel must handle the machine
to carry out maintenance and repair operations.
BLOW THE INSIDE OF THE MACHINE
WITH COMPRESSED AIR FROM TIME TO TIME.
The accumulation on the inside of metal dust is
one of the main causes of breakdowns in this type
of equipment as they are subject to the great
amount of pollution caused by the cutting process.
The equipment must be kept separate from the
cutting place, not placing it a short distance away.
Keeping the machine clean and dry is essential.
The inside must be blown as required. We must
avoid any anomaly or deterioration due to the
accumulation of dust. Blow the two inside volumes
of the equipment with clean dry compressed air.
- Control volume (upper): Electronic plates,
contactors, auxiliary transformer and switches.
- Power volume (lower): Rectifier and main
transformer.
FROM TIME TO TIME DISCHARGE THE
WATER WHICH HAS CONDENSATED ON THE
FILTER-REGULATOR
Control the non-existence of liquid in the glass of
filter F situated on the rear of the apparatus. When
the air intake is disconnected an automatic
discharge takes place. The discharge can be done
manually by pressing the valve that exists on the
lower part of the glass.
PLACE THE EQUIPMENT SOMEWHERE
WHERE CLEAN AIR IS RENEWED.
The machine ventilations must be kept free. It
must be located in a place where clean air is
renewed.
GAR CUT (V. PROFESSIONAL). Instructions Manual.
KEEP THE MACHINE PANELS CLOSED.
DO NOT DISCONNECT THE MACHINE IF
IT IS HOT.
If you have finished the cutting work do not
disconnect the machine immediately, wait until the
inner cooling system has totally cooled it.
DO NOT EXCEED THE DUTY CYCLE OF
THE MACHINE.
Do not exceed the equipment operating factor.
You must not wait until the thermal switch
automatically disconnects the equipment. Control
the heating.
4.2 MAINTENANCE OF THE PLASMA TORCH.
GENERAL RECOMMENDATIONS.
The plasma torch is the main element of the
system. A badly maintained torch makes the
cutting operation difficult, speeding up the wear of
the consumable elements.
The plasma torch has a safety system which
prevents the existence of dangerous voltages when
the consumable elements
repaired.
However always remember to:
DISCONNECT THE MACHINE WHEN
HANDLING THE TORCH BODY
