1.3 Radiation
•Warning! The radiation of the arc can lead to eye damage and skin burns. Do not look into
the arc with unprotected eyes. Therefore, a shield or a protective helmet should be used to
protect the eyes. Use a welding protection shield with the prescribed DIN protective glass.
•With insufficient protection, a glare or burn of the retina, but also after a few hours a very
painful conjunctivitis may arise.
•The arc emits not only light and heat rays but also UV rays. These UV rays may have sunburn-
like effects on unprotected body sites. The skin must therefore be protected by suitable
protective clothing (welding gloves, leather apron, safety shoes).
•Persons in the vicinity of the arc must be made aware of the dangers and provided with the
necessary protection against arc radiation.
1.4 Fire
•Warning! Sweat sparks can cause fire. Make sure they do not splash through the entire
welding area.
•Flammable substances should be kept away from the cutting zone. They could be ignited by
sparks and hot slag.
•Place the device at least 11.81 in (30 cm) away from surrounding objects.
•Do not place the device on a heated surface.
•After finishing your work, check the environment for smoldering and burning.
1.5 Electrical hazard
•Before putting the device into operation, have it expertly checked whether the earthing, the
neutral conductor and the residual current circuit of your electrical home system comply
with the safety regulations and function perfectly (fuse protection, cable cross-section).
•Warning! Electric shock can lead to death! Do not touch any live parts, such as welding
power sockets, pencil, tungsten or wire electrodes directly!
•Make sure you are isolated from the earth and the workshop.
•When welding, always wear insulating gloves on both hands (protection against electric
shock and burns caused by red-hot spatter).
•Set up the grounding connector according to the appropriate standard. It is forbidden to
touch the electrical parts and the electrode when the skin is not covered, or when wearing
wet gloves or clothing.
•Cutting blowpipes should not be clamped under the arm or kept close to the body. There is a
risk that electrical current can flow through the human body.

•In continuous use, sufficient hearing protection must be worn. Use earmuffs or other aids to
protect the ear.
•Nearby working people are also protected from noise.
1.7 Danger of accident through supply lines
•Warning! Improperly installed cables (mains, control, welding cables or intermediate hose
packages) can cause tripping hazards.
•Lay the supply lines flat on the ground (avoid looping).
•Avoid laying on walking or conveying paths.
1.8 Gas pressure equipment
•Gas cylinders are under high pressure and represent a danger source. Proper handling of
them is absolutely necessary to inquire the gas supplier.
•For example, the bottles must be protected from direct sunlight, open fire and strong
temperature fluctuations, e.g. very low temperatures.
•Gas containers and accessories must be kept in perfect condition. Make sure that only
•approved parts, such as hoses, couplings, pressure reducers, etc. are used.
•Connections must not be lubricated with oil or grease.
1.9 Magnetic fields
•Warning! Persons wearing an electronic life-support device (such as a pacemaker, etc.)
should consult their physician before going anywhere near arc, cutting, burn-out or spot
welding equipment to ensure that the magnetic fields associated with the high electrical
currents do not affect their devices.
2.Intended use
•The plasma cutter is suitable for small and varied applications with excellent cutting results.
Almost all conductive metals can be cut. These are for example high-alloyed chrome-nickel
steels, all hardened and unhardened tool steels, structural steels up to non-ferrous metals
such as aluminum and its compounds, brass, copper, even gray cast iron can be cut with it.
•The device is used to center cut steel cut up to 0.472 in (12 mm).
•Clean cuts that do not require post-processing.
•Only operation with compressed air is permitted. Do not use other gases.
•Attention! Never use the device for any other purpose.
