• Other devices such as hearing aids, pacemakers, etc., may malfunction while the welding machine
is in operation.
Sources of danger during arc welding
Arc welding is associated with a number of sources of danger. It is therefore particularly important
for the welder to observe the following rules in order not to endanger himself and others and to
avoid injury/damage to people and equipment.
• In accordance with national and local regulations, work on the mains voltage side, e.g. on cables,
plugs, sockets, etc., should only be carried out by a quali ed electrician.
• In the event of an accident, immediately disconnect the welding machine from the mains voltage.
• If electrical touch voltages occur, switch o the device immediately and have it checked by a qua-
li ed electrician.
• Make sure there are secure electrical contacts on the welding current side.
• When welding, wear insulating welding gloves on both hands to protect against electric shock,
harmful radiation, glowing metal and spatter.
• Use sturdy, insulating footwear that also insulates in wet conditions. Low shoes are unsuitable as
falling, glowing metal droplets can result in burns.
• Wear appropriate protective clothing and avoid synthetic materials.
• Do not stare into the arc without protection. Use a welding shield with protective glass in accor-
dance with DIN regulations. The arc not only emits light and heat rays, but also invisible UV rays,
which can lead to conjunctivitis and skin burns.
• Individuals in the vicinity of the arc must be alerted to the dangers and equipped with appropriate
protective equipment. If necessary, erect protective walls.
• When welding, especially in con ned spaces, make sure that there is a su cient supply of fresh air,
as smoke and harmful gases are generated.
• Avoid welding work on containers that contain or have contained gases, fuels, mineral oils or simi-
lar, as there is a risk of explosion due to residual materials.
• Adhere to special regulations in rooms where there is a risk of re and explosion. Welded joints
are subject to speci c safety requirements and should only be worked on by especially trained and
certi ed welders.
• ATTENTION! Always connect the earth terminal as close as possible to the welding point so that the
welding current can travel the shortest possible distance from the electrode to the earth terminal.
• Never connect the earth terminal to the housing of the welding machine! Do not connect the earth
terminal to earthed (grounded) parts far from the workpiece. Otherwise, the protective conductor
system of the room in which you are welding could be damaged.
• Do not use the welding machine in the rain or in a damp environment.
• Always place the welding machine on a level surface.
• The output is rated at an ambient temperature of 20°C. Welding times may be reduced at higher
temperatures.

Hazard due to electric shock:
An electric shock from a welding electrode can be fatal. Do not weld in rainy or snowy conditions.
Wear dry insulating gloves. Do not touch the electrode with your bare hands.
Do not wear wet or damaged gloves. Protect yourself from electrical shock by insulating against the
workpiece. Do not open the machine housing.
Danger from welding fumes:
Inhalation of welding fumes can endanger your health. Do not put your head into the smoke. Use
the equipment in open areas. Use ventilation to remove the smoke.
Danger from welding sparks:
Welding sparks can give rise to an explosion or a re. Keep ammable materials away from the
welding site. Do not weld next to ammable materials. Welding sparks can cause res. Keep a re
extinguisher close by and an observer who can use it immediately. Do not perform welding on
drums or any closed containers.
Dangers from welding sparks:
Arc rays can damage your eyes and damage your skin. Wear a hat and safety goggles. Wear hearing
protection and a shirt with high collar. Wear a protective welding helmet and correctly sized lters.
Wear full body protection.
Exposure to electromagnetic elds:
Welding current generates electromagnetic elds. Do not use with medical implants. Never wrap
the welding lines around your body. Keep the welding cables together.
Environment with an increased electrical hazard
• Observe the following safety instructions when welding in environments with an increased elec-
trical hazard. Such environments with an increased electrical hazard can occur in the following
situations: at workplaces where the work area is restricted, so that the welder is operating in a
forced position (e.g. kneeling, sitting, lying) and is touching electrically conductive components;
• At workplaces that are fully or partially electrically conductive and where there is a high risk of
preventable or accidental contact by the welder;
• In wet, humid or hot workplaces where humidity or perspiration signi cantly reduces the resistan-
ce of human skin and the insulating properties or protective equipment.
• A metal ladder or sca olding can also create an environment with an increased electrical hazard.
Using the carrying strap
Welding must not be carried out when the ux-cored wire welding machine is being carried, for
example using the carrying strap.
• This is to prevent the following risks: The risk of losing balance when connected cables are pulled.
• Increased risk of electric shock as the welder comes into contact with the earth when using a Class
