Check and evaluate the immunity to interference of nearby devices according to national
and international regulations. Examples of equipment that may be susceptible to interfer-

-
Specific hazards
Keep hands, hair, clothing and tools away from moving parts. For example:
-
-
-
-
-
Do not reach into the rotating cogs of the wire drive or into rotating drive components.
Covers and side panels may only be opened/removed while maintenance or repair work is

The welding wire emerging from the welding torch poses a high risk of injury (piercing of
the hand, injuries to the face and eyes, etc.).
Therefore always keep the welding torch away from the body (devices with wire-feed unit)
and wear suitable protective goggles.

Safety devices
Power, signal and data transfer lines
IT and telecommunications devices
Measuring and calibrating devices
Mains supply
-
If electromagnetic interference arises despite correct mains connection, addition-
al measures are necessary (e.g. use a suitable line filter).
Welding power leads
-
must be kept as short as possible
-
must run close together (to avoid EMF problems)
-
must be kept well apart from other leads
Equipotential bonding
Earthing of the workpiece
-
If necessary, establish an earth connection using suitable capacitors.
Shielding, if necessary
-
Shield off other nearby devices
-
Shield off entire welding installation
effects on the health of others in the vicinity, e.g. wearers of pacemakers and hearing
aids
wearers of pacemakers must seek advice from their doctor before approaching the de-
vice or any welding that is in progress
for safety reasons, keep distances between the welding cables and the welder's head/
torso as large as possible
do not carry welding cables and hosepacks over the shoulders or wind them around
any part of the body
Fans
Cogs
Rollers
Shafts
Wirespools and welding wires
Ensure that all covers are closed and all side panels are fitted properly.
Keep all covers and side panels closed.
