Hazards from
mains and weld-
ing current
The harmfulness of the welding fumes will depend on e.g. the following
components:
- the metals used in and for the workpiece
- the electrodes
- coatings
- cleaning and degreasing agents and the like
For this reason, pay attention to the relevant Materials Safety Data Sheets
and the information given by the manufacturer regarding the components
listed above.
Keep all flammable vapors (e.g. from solvents) well away from the arc
radiation.
Flying sparks can cause fires and explosions!
Never perform welding anywhere near combustible materials.
Combustible materials must be at least 11 meters (35 feet) away from the
arc, or else must be covered over with approved coverings.
Have a suitable, approved fire extinguisher at the ready.
Sparks and hot metal particles may also get into surrounding areas through
small cracks and openings. Take suitable measures here to ensure that
there is no risk of injury or fire.
Do not perform welding in locations that are at risk from fire and/or
explosion, or in enclosed tanks, barrels or pipes, unless these latter have
been prepared for welding in accordance with the relevant national and
international standards.
Welding must NEVER be performed on containers that have had gases,
fuels, mineral oils etc. stored in them. Even small traces of these
substances left in the containers are a major explosion hazard.
An electric shock is potentially life-threatening, and can be fatal.
Do not touch any live parts, either inside or outside the machine.
In MIG/MAG and TIG welding, the welding wire, the wire spool, the drive
rollers and all metal parts having contact with the welding wire are also live.
Always place the wirefeeder on an adequately insulated floor or base, or
else use a suitable insulating wirefeeder holder.
Ensure sufficient protection for yourself and for other people by means of a
dry base or cover that provides adequate insulation against the ground/
frame potential. The base or cover must completely cover the entire area
between your body and the ground/frame potential.
All cables and other leads must be firmly attached, undamaged, properly
insulated and adequately dimensioned. Immediately replace any loose
connections, scorched, damaged or underdimensioned cables or other
leads.
