General safety regulations
Note! All instructions must be read. Failure to observe the following instructions may lead to
electric shock, fire and/or severe injuries. You must also observe the accident prevention and
work protection regulations of the Association of Metalworkers (BGV D1, BGI 855 etc.).
1. Workplace
a) Keep your workplace clean and tidy. Disorganized and poorly lit work areas can lead to
accidents. Be prudent, before beginning work carefully consider all the steps you need to
take in order to perform your work. Do not operate the device when you are tired or under
the influence of medication, alcohol or drugs.
b) Switch off the device when you are finished – set the on/off switch on the front of the device
to O. Remove the power plug from the power socket. Do not leave the device switched on
and unattended.
c) Only place the electrode clamp on an insulated surface, regardless of whether a welding
electrode is inserted. Avoid short circuits with the earthing clamp. Remove the electrode
from the electrode clamp when welding is interrupted or finished.
d) Switch off the device - set the on/off switch on the front of the device to O and remove the
power plug from the mains socket – when you make any changes to your workplace, when
removing the welding cable(s), and when cleaning or transporting the device.
e) Do not use the device in environments presenting a danger of explosion, or where
inflammable liquids, gases or dust are present. Welding devices generate sparks and
molten metal that can ignite dust or fumes.
f) Remove all inflammable substances and materials from the workplace. Welding devices
generate sparks and molten metal that can ignite these materials. Note that, through the
welding shield, you cannot recognise a fire that may occur during welding.
g) Do not weld empty containers, vessels or pipes that previously contained inflammable
liquids such as fuels, mineral oil or gas. Even when these were emptied a long time ago.
Even the smallest residue can present a danger of explosion.
h) Ensure adequate ventilation. Use a suitable air extraction system. Welding with coated
electrodes produces unhealthy smoke. When welding with high-alloy electrodes, e.g. for
stainless high-alloy Chrome-Nickel steel, be sure to use an air extraction system. The
smoke and gases produced are particularly unhealthy.
i) Ensure that adequate fresh air is available, especially in very small spaces.
j) Warn persons in the area of the danger to eyesight by hanging a sign in the workplace
stating “Warning! Do not look at the welding arc”.
