Test and assess the immunity of equipment in the vicinity of the device in accordance with
national and international provisions. Examples of interference-prone equipment that could
be affected by the device:
-
Safety devices
-
Grid power lines, signal lines and data transfer lines
-
EMC and telecommunications equipment
-
Devices for measuring and calibrating
Supporting measures to avoid EMC problems:
1.
Grid power supply
-
If electromagnetic interference occurs despite a grid connection that complies
with regulations, take additional measures (e.g., use a suitable grid filter).
2.
Welding power-leads
-
Keep them as short as possible
-
Route them close together (also to avoid EMF problems)
-
Route them far from other lines
3.
Equipotential bonding
4.
Workpiece grounding
-
If necessary, establish grounding using suitable capacitors
5.
Shield, if necessary
-
Shield other devices in the vicinity
-
Shield the entire welding installation
EMF measures
Electromagnetic fields may cause health problems that are not yet known:
-
Effects on the health of persons close by, e.g., those with pacemakers and hearing
aids
-
Persons with pacemakers must seek advice from their doctor before staying in the im-
mediate vicinity of the device and the welding process
-
Keep distances between welding cables and the head/torso of the welder as large as
possible for safety reasons
-
Do not carry welding cables and hosepacks over one's shoulder or wrap them around
one's body or body parts
Particular Hazard
Areas
Keep hands, hair, loose clothing, and tools away from moving parts, such as:
-
fans
-
gears
-
rollers
-
shafts
-
wirespools and welding wires.
Do not reach into rotating gears of the wire drive or into rotating drive parts.
Covers and side parts must only be opened/removed during maintenance and repair work.
During operation:
-
Ensure that all covers are closed, and all side parts have been mounted properly.
-
Keep all covers and side parts closed.
The protrusion of welding wire from the welding torch represents a high risk of injury (cuts
to the hand, facial and eye injuries, etc.)
Therefore always hold the welding torch away from the body (devices with wirefeeder) and
use suitable protective goggles.
Do not touch the workpiece during or after welding—burning hazard.
Slag may fly off cooling workpieces. Therefore, also wear regulation-compliant protective
equipment when reworking workpieces and ensure that other persons are sufficiently pro-
tected.
