Warning!
• Opening the welding unit as well as a work inside the casing
may
only be carried out by authorized electrical specialists.
• Prior to closing the welding unit the connection of the protective
conductor to the unit casing must be re-established!
• If the plastic protection must be removed for repairing the unit,
always be sure to replace it prior to applying power to the unit.
Safety measures in case of increased electrical danger:
Increased electrical danger is to hand particularly when working:
• In confined spaces with electrically conductive walls
• In wet, damp, extremely dry and hot rooms with restricted freedom of movement
on electrically conductive parts (metallic ladders, scaffolding, mounting rails, floor
plates, etc.)
• In confined conditions between or on electrically conductive
parts
Under these working conditions, the following protective measures
must be taken:
• The welder must be adequately protected against electrical dangers by using
insulating underlay or intermediary layers
• The insulating materials must be applied in such a way that touching conductive
parts, damp walls and damp flooring can be
ruled out
For the use of insulating materials is not possible due to additional dangers (risk of
falling, special room conditions, etc.), work may at least only be done in dry,
undamaged working clothes.
Safety features of the welding unit
The Nelweld welding unit bears the S sign and is suited for welding
under increased electrical danger.
• The power unit hardware does not allow the output voltage to
exceed 75V.
