Personal Protection
Welding fumes and gases
The air inhaled by the welder must be kept free from harmful substances caused
during welding process. The ventilation required depends on the size of the
enclosed working area, the type of material used and the duration of the welding
process. In some cases, ventilation (e.g. fan) may be sufficient, but usually an
extraction system is necessary where harmful substances are produced.
Danger from shielding-gas cylinder
Shielding-gas cylinders contain pressurized gas and may explode if they are
damaged. As shielding-gas cylinders are an integral part of the overall welding
outfit, they also have to be treated with great care.
Protect shielding-gas cylinders containing compressed gas from excessive heat,
mechanical impact, slag, naked flames, sparks and arcs.
Mount the shielding-gas cylinders in the vertical and fasten them in such away that
they cannot fall over (i.e. as shown in the instruction manual).
Keep shielding-gas cylinders well away from welding circuits (and, indeed, from
any other electrical circuits).
Never hang a welding torch on a shielding-gas cylinder.
Never touch a shielding-gas cylinder with a welding electrode.
accessories.
Operating manual
The face and the eyes must be protected by a welder's shield
with lenses - protection category corresponding to the intensity
of current.
Persons working close by must also be adequately protected
from arc radiation.
To protect your hearing against noise,
wear ear-protectors!
Protect your hands and feet by wearing stout footwear and
appropriate gloves.
