Prevention against electric shocks
The machine must be installed by
authorised persons with specific technical
and professional know-how, conforming to
the laws in force in the country where it is
installed.
Before connecting the power source to the mains,
always check that:
•
the voltage received falls within ±10% allowance of
the nominal value displayed on the machine plate;
•
the mains input is properly grounded (as provided in
the relevant legislation) and the yellow/green wire of
the welding machine is connected to the ground;
•
the mains supply is equipped with a grounded
neutral conductor;
•
the power source is in a dry and ventilated place.
When using the machine, make sure that the following
precautionary measures are taken in the workplace:
•
ensure that no metallic body may accidentally get
into contact with the power cables;
•
do not carry out any welding operation in damp or
wet areas;
•
ground any metallic parts falling within the operator's
reach;
•
keep all flammable materials away from the working·
area;
•
connect the work return lead of the cutting circuit to a
place as close as possible to the cutting area in order
to minimise the current path and the relevant risks;
•
make sure that cutting torches and cables are in
perfect condition.
WARNING! Since the operating voltage in a plasma
cutting circuit may range between 100V and 500V
(vs. 10÷100V in a welding circuit) special attention
should be paid to the maintenance and wear
condition of cables and torches. Non-insulated
parts of the torch should never be touched as they
represent a serious danger of electrocution.
Furthermore, the operator should stick to the following
behavioural rules:
•
do not connect plasma cutting machines in series or
parallel;
•
in the case two or more cutters should operate on
electrically connected parts, it is suggested that they
work at a suitable distance from each other and that
none of them touches two torches at the same time;
•
do not place the torch on metallic surfaces: this might
be a condition for the machine to be started
accidentally;
•
always wear insulating garments.

Prevention against UV rays, fumes
and fires
Arc cutting is a process by which UV rays are
emitted. Operators should therefore protect
their eyes and faces with suitable face
masks or helmets equipped with adequate
filter lenses.
Recommended DIN protection grades for filter lenses
are listed below for plasma cutting procedure in relation
of current used:
•
grade 11 - up to 150 Amps
•
grade 12 - from 150 to 250 Amps
•
grade 13 - over 250 Amps
Operators should wear gauntlets, insulating shoes and
fireproof clothes to protect themselves from radiation,
slags and sparks.
Reflection and transmission of UV rays in workplaces
should be reduced by using antiflash welding screens
or panels.
In order to reduce the toxic action of cutting
fumes, it is suggested to operate in
ventilated areas. Use fume extractors close
to the cutting area, if ventilation is poor or
lacking.
If the piece to be cutted is covered by chemicals
(solvents, paints, etc.), it should be carefully cleaned
prior to welding to prevent toxic gas emission.

Make sure that cutting torche and
cables are in perfect condition.
It is strictly forbidden to plasma cut
on fuel tanks, whether they are full
or empty.
Fire and/or explosion hazard!
