Welding In Tight Spaces - Parkside PTMI 180 A1 Originalbetriebsanleitung

In wet, humid or hot workplaces where the air humidity or sweat
„
significantly reduces the resistance of human skin and the insulating
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
output voltage of the welder must not 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.
In this case, before starting the welding procedure, an expert
must carry out an assessment in order to determine what steps
are necessary, in order to guarantee safety at work and which
precautionary measures should be taken during the actual welding
procedure.
z Total of no-load voltages
When more than one welding power source is operated at the
„
same time, their no-load voltages may add up and lead to an
increased electrical hazard. Welding power sources must be
connected in such a way that the danger is minimised.
