EMC precautions
(Fortsetzung)
Particular danger
spots
- users of heart pacemakers must take medical advice before going
anywhere near welding equipment or welding workplaces
Electromagnetic fields may cause as yet unknown damage to health.
Ancillary measures for preventing EMC problems:
a) Mains supply
- If electromagnetic interference still occurs, despite the fact that the
mains connection is in accordance with the regulations, take additional
measures (e.g. use a suitable mains filter).
b) Welding cables
- Keep these as short as possible
- Arrange them so that they run close together
- Lay them well away from other leads.
c) Equipotential bonding
d) Workpiece grounding (earthing)
- where necessary, run the connection to ground (earth) via suitable
capacitors.
e) Shielding, where necessary
- Shield other equipment in the vicinity
- Shield the entire welding installation.
Keep your hands, hair, clothing and tools well away from all moving parts,
e.g.:
- fans
- toothed wheels
- rollers
- shafts
- wire-spools and welding wires
Do not put your fingers anywhere near the rotating toothed wheels of the
wirefeeder units / wiredrives for the TIG hot wire.
Covers and sideguards may only be opened or removed for as long as is
absolutely necessary to carry out maintenance and repair work.
While the machine is in use:
- ensure that all the covers are closed and that all the sideguards are
properly mounted ...
- ... and that all covers and sideguards are kept closed.
When the welding wire emerges from the wire infeed unit on the torch, there
is a high risk of injury (the wire may pierce the welder's hand, injure his face
and eyes ...). For this reason, when feeder-inching etc., always hold the
torch so that it is pointing away from your body.
Do not touch the workpiece during and after welding - risk of injury from
burning!
Slag may suddenly "jump" off workpieces as they cool. For this reason,
continue to wear the regulation protective gear, and to ensure that other
persons are suitably protected, when doing post-weld finishing on
workpieces.
