HELPFUL HINTS
• If the system air contains considerable amounts of moisture
and oil, it is best to use a drying filter to avoid excessive
oxidation and wear on consumable parts, damage to the
torch and a reduction in the speed and quality of the cutting.
• Make sure that the new electrode and nozzle to be mounted
are thoroughly clean and degreased.
• Always use original spare parts to avoid damaging the
torch.
MAINTENANCE
Always cut off the power supply to the machine before any
operation, which must always be carried out by qualified
personnel (CEI 26-29 / IEC 60974-4).
PLASMA CUTTER MAINTENANCE
In the case of maintenance inside the machine, make sure
that the switch C is in position O and that the power cord is
disconnected from the mains.
Even though the machine is equipped with an automatic
condensation drainage device that is tripped each time the
air supply is closed, it is good practice to periodically make
sure that there is no condensation accumulated in the water
trap I (fig.1).
It is also necessary to periodically clean the interior of the
machine from the accumulated metal dust, using com-
pressed air.
PRECAUTIONS AFTER REPAIRS.
After making repairs, take care to organize the wiring so that
there is secure insulation between the primary and
secondary sides of the machine. In particular, make sure
that the casing 50 is mounted (see exploded drawing). Do
not allow the wires to come into contact with moving parts or
those that heat up during operation. Reassemble all clamps
as they were on the original machine, to prevent a
connection from occurring between the primary and
secondary circuits should a wire accidentally break or be
disconnected.
Also mount the screws with geared washers as on the
original machine.
