Safety instructions
Safety /2
Take care to avoid fire hazards
•
Containers in which fuels or lubricants have been present must be thoroughly cleaned before
welding begins. It is not sufficient simply for the receptacle to be empty.
•
After a workpiece has been welded, it must only be touched or brought into contact with
inflammable material when it has cooled down sufficiently.
•
Loose welding connections can completely destroy protective conductor systems of interior
installations and cause fires. Before beginning welding work, ensure that the earth tongs are
properly fixed to the workpiece or welding bench and that there is a direct electrical connection
from the workpiece to the power source.
Noise exceeding 70 dBA can cause permanent hearing damage
•
Wear suitable earmuffs or plugs.
•
Ensure that other people who spend time in the working area are not inconvenienced by the
noise.
Secure gas cylinder
•
Place shielding gas cylinders in the holders provided for them and secure with safety chains.
•
Take care when handling cylinders; do not throw or heat, guard against them toppling over.
•
When moving by crane, take off the gas cylinder from the welding machine.
Caution: Interference by electrical and electromagnetic fields is possible e.g. from the
welding machine or from the high-voltage pulses of the ignition unit.
•
As laid down in Electromagnetic Compatibility Standard EN 50199, the machines are intended
for use in industrial areas; if they are operated e.g. in residential environments problems can
occur in ensuring electromagnetic compatibility.
•
The functioning of heart pacemakers can be adversely affected when you are standing near
the welding machine.
•
Malfunctioning of electronic equipment (e.g. EDP, CNC equipment) in the vicinity of the
welding location is possible.
•
Other mains supply leads, trip leads, signal and telecommunications leads above, under and
near the welding device may be subject to interference.
Warning: Electromagnetic interference must be reduced to such a level that it no longer
constitutes interference.
Possible reduction measures:
•
Welding machines should be regularly maintained (see Sect. “Maintenance and care”)
•
Welding leads should be as short as possible and run closely together on or near to the
ground.
•
Selective shielding of other leads and equipment in the environment can reduce radiation.
Caution: Repairs and modifications may only be carried out by authorised, trained,
specialist personnel.
The warranty becomes null and void in the event of unauthorised interference.
Our operating instructions will provide you with an introduction into the safe use of the
machine.
Therefore please read them closely and only start work when you are familiar with them.
