Welding and cutting cables
To minimise the effects of electromagnetic fields follow the fol-
lowing instructions:
- Where possible, collect and secure the earth and power
cables together.
- Never coil the welding cables around your body.
- Do not place your body in between the earth and power
cables (keep both on the same side).
- The cables must be kept as short as possible, positioned as
close as possible to each other and laid at or approximately at
ground level.
- Position the equipment at some distance from the welding
area.
- The cables must be kept away from any other cables.
Earthing connection
The earth connection of all the metal components in the weld-
ing (cutting) equipment and in the close aerea must be taken in
consideration.
The earthing connection must be made according to the local
regulations.
Earthing the workpiece
When the workpiece is not earthed for electrical safety reasons
or due to its size and position, the earthing of the workpiece
may reduce the emissions. It is important to remember that
the earthing of the workpiece should neither increase the risk
of accidents for the user nor damage other electric equipment.
The earthing must be made according to the local regulations.
Shielding
The selective shielding of other cables and equipment present
in the surrounding area may reduce the problems due to elec-
tromagnetic interference. The shielding of the entire welding
(cutting) equipment can be taken in considered for special
applications.
2 INSTALLATION
Installation should be performed only by expert
personnel authorised by the manufacturer.
During installation, ensure that the power source
is disconnected from the mains.
2.1 Commissioning
Before starting work, it is necessary to carry out the following
checks and work:
1. Check that the generator is turned off.
2. Check that all the parts of the torch are working. For the
various parts that make up the torch body, the sequence of
correct assembly is 1-2-3-4-5.
3. Check that the air diffuser, or "swirl-bush" (2) is working cor-
rectly, which must always show access holes free of obstruc-
tion; the use of a defective air diffuser would cause overheat-
ing, with consequent damage to the components of the torch
body.
4. With the spare parts assembled, check that by screwing the
outer nozzle (4) to the torch body the corresponding alarm
on the generator is cut off; finally check that by unscrewing
the nozzle the alarm is triggered; these checks should be car-
ried out with the generator on, taking care not
to press the torch button.
5. The compressed air used must be filtered and maintained at
a high level of purity; humid air, oil and other contaminative
agents must be removed, by making use of suitable driers and
anti- oil filters.
Thus the torch is set up for the cutting operation.
In any case it is necessary to also follow what is shown in the
instruction manual for the generator, above all in the para-
graphs "Warning", "Connection" and "Maintenance".
