• Do not carry out plasma cutting on drums or any
other closed containers. Danger from arc beams:
• Arc beams can damage your eyes and injure your
skin.
• Wear a hat and safety goggles.
• Wear hearing protection and high, closed shirt col-
lars.
• Use a welding safety helmet and make sure that
the filter setting is correct.
• Wear complete body protection. Danger from elec-
tromagnetic fields:
• Cutting current generates electromagnetic fields.
• Do not use if you have a medical implant.
• Never wrap the cutting cable around your body.
• Guide cutting cables together. Welding shield-spe-
cific safety instructions
• With the help of a bright light source (e.g. light-
er) examine the proper functioning of the welding
shield prior to starting with any cutting work.
• Cut spatters can damage the protective screen.
Immediately replace damaged or scratched pro-
tective screens.
• Immediately replace damaged or highly contami-
nated or splattered components.
• The device must only be operated by people over
the age of 16.
• Please familiarise yourself with the cutting safety
instructions. To that end, you must also observe
the safety instructions of your plasma cutter.
• Always wear a welding helmet while welding and
plasma cutting. If it is not used, you could sustain
severe lesions to the retina.
• Always wear protective clothing during welding
and plasma cutting operations.
• Never use the welding shield without the protective
screen because this could damage the optical unit.
There is a risk of damage to the eyes!
• Regularly replace the protective screen to ensure
good visibility and fatigue proof work.
Environment with increased electrical hazard
Environments with increased electrical hazard may
be encountered, for example:
• In workplaces where the space for movement is
restricted, such that the operator is working in a
forced posture (e.g.: kneeling, sitting, lying) and is
touching electrically conductive parts;
• In workplaces which are restricted completely or in
part in terms of electrical conductivity and where
there is a high risk through avoidable or accidental
touching by the operator;
• In wet, humid or hot workplaces where the air hu-
midity or weld significantly reduces the resistance
of human skin and the insulating properties or ef-
fect of protective equipment.
• Even a metal conductor or scaffolding can create
an environment with increased electrical hazard.

• When using plasma cutters under electrically dan-
gerous conditions, the output voltage of the plas-
ma cutter must be greater than 48 volt when idling
(effective value).
• The plasma cutter may not be used in these cases
due to the output voltage.
Plasma cutting in tight spaces
• When welding and plasma cutting in tight spaces
this may pose a hazard through toxic gases (risk
of suffocation). In tight spaces the device may on-
ly be operated if there are trained individuals in the
immediate vicinity who can intervene if necessary.
In this case, before starting to use the plasma cut-
ter, an expert must carry out an assessment in or-
der to determine what steps are necessary, in or-
der to guarantee safety at work and which precau-
tionary measures should be taken during the actu-
al cutting procedure.
Total of open circuit voltages
• When more than one plasma power source is op-
erated at the same time, their open circuit voltag-
es may add up and lead to an increased electrical
hazard. The plasma power sources must be clear-
ly marked with their individual control units and
connections, in order to be able to identify which
device belongs to which circuit.
Using shoulder straps
• The plasma cutter must not be used if the device is
being carried e.g. with a shoulder strap.
This is intended to prevent:
• The risk of losing your balance if the lines or hoses
which are connected are pulled.
• The increased risk of an electric shock as the op-
erator comes into contact with the earth if he/she is
using a Class I plasma cutter, the housing of which
is earthed through its conductor.
Protective clothing
• At work, the operator must protect his/her whole
body by using appropriate clothing and face pro-
tection against radiations and burns. The following
steps must be observed:
• Wear protective clothing prior to cutting work.
• Wear gloves.
• Open windows to guarantee air supply.
• Wear protective goggles.
• Gauntlet gloves made of a suitable material (leath-
er) must be worn on both hands. They must be in
perfect condition.
• A suitable apron must be worn to protect clothing
from flying sparks and burns. When specific work,
e.g. overhead cutting, is required, a protective suit
must be worn and, if necessary, even head protec-
tion.
