site is close to radio or television receivers). In this case, the operator is obligated to implement appropriate
remedial measures. Test and evaluate the interference immunity of equipment in the environment of the device
in accordance with the national and international provisions. Examples of interference-prone equipment that
could be influenced by the device:
♦ Safety devices
♦ Mains, signal and data transmission lines
♦ IT and telecommunications equipment
♦ Equipment for measurement and calibration
Supportive measures for the avoidance of EMC problems:
1. Mains supply
♦ If electromagnetic interference arises despite mains connection in accordance with regulations,
implement additional measures (e.g. use a suitable mains filter).
2. Welding lines
♦ must be kept as short as possible
♦ must be laid close together (also for the avoidance of EMC problems)
♦ must be laid far from other lines
3. Equipotential bonding
4. Screening, if necessary
♦ Screen other equipment in the environment
♦ Screen the entire welding installation
EMC measures: Electromagnetic fields could cause health damage that is not yet known:
♦ Electromagnetic fields can influence the health of persons in the vicinity, e.g. wearers of pacemakers
and hearing aids
♦ Persons wearing pacemakers must consult their doctor before entering the immediate vicinity
ofthedevice and the welding process.
♦ Keep distances between welding cables and the head/torso of the welder as great as possible for safety
reasons
♦ Do not carry welding cable and hose packages over the shoulder and do not wind around the body
orbody parts
4.9 During operation
♦ The workpiece can get hot during welding.
♦ Particular regulations apply to areas at risk of fire and explosion; observe the relevant national
andinternational provisions.
If the device is equipped with a carry handle, this is intended exclusively for carrying by hand. The carry handle
is not suitable for transport with a crane, forklift truck or other mechanical hoisting equipment.
4.10 Danger due to shielding gas canisters
Shielding gas canisters contain pressurised gas and could explode if damaged. Because shielding gas
canisters are part of the welding equipment, they must be handled extremely carefully. Protect shielding gas
canisters with compressed gas against
