z Environment with increased electrical hazard
When welding in environments with increased electrical hazard,
the following safety instructions must be observed. Environments with
increased electrical hazard may be encountered, for example:
In workplaces where the space for movement is restricted, such
„
that the welder 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 welder;
In wet, humid or hot workplaces where the air humidity or sweat
„
significantly reduces the resistance of human skin and the insulat-
ing properties or effect of protective equipment.
Even a metal conductor or scaffolding can create an environment
„
with increased electrical hazard.
In this type of environment, insulated mats and pads must be used.
Furthermore gauntlet gloves and head protection made of leather or
other insulating materials must be worn to insulate the body against
Earth. The welding power source must be located outside the working
area or electrically conductive surfaces and out of the welder's reach.
Additional protection against a shock from the mains power in the
event of a fault can be provided by using a fault-circuit interrupter,
which is operated with a leakage current of no more than 30 mA and
covers all mains-powered devices in close proximity. The fault-circuit
interrupter must be suitable for all types of current.
There must be means of rapid electrical isolation of the welding
power source or the welding circuit (e.g. emergency stop device)
which are easily accessible.
When using welders under electrically dangerous conditions, the out-
put voltage of the welder must be greater than 113 volt when idling
(peak value). Based on the output voltage this welder may be used in
these conditions.
z Welding in tight spaces
When welding in tight spaces this may pose a hazard through
„
toxic gases (risk of suffocation).
In tight spaces you may only weld if there are trained individuals
„
in the immediate vicinity who can intervene if necessary.
