Do not use damaged or modified batteries and power sources. Damaged or modified com -
ponents and devices may exhibit unpredictable behaviour which can lead to explosions or
injury.
Do not expose the power source or battery to fire or temperatures exceeding 130 °C (266
°F). This may result in an explosion.
Observe the charging instructions contained in these Operating Instructions. Do not charge
the batteries outside the permitted temperature range - see section Environmental con -
ditions on page 19 . Improper charging or unauthorised temperatures may damage the
battery and increase the risk of fire.
Meandering weld -
ing currents
If the following instructions are ignored, meandering welding currents can develop with the
following consequences:
- Fire hazard
- Overheating of parts connected to the workpiece
- Irreparable damage to ground conductors
- Damage to device and other electrical equipment
Ensure that the workpiece is held securely by the workpiece clamp.
Attach the workpiece clamp as close as possible to the area that is to be welded.
If the floor is electrically conductive, the device must be set up with sufficient insulating ma -
terial to insulate it from the floor.
If distribution boards, twin-head mounts, etc., are being used, note the following: The elec -
trode of the welding torch / electrode holder that is not used is also live. Make sure that the
welding torch / electrode holder that is not used is kept sufficiently insulated.
EMC measures In certain cases, even though a device complies with the standard limit values for emis -
sions, it may affect the application area for which it was designed (e.g. when there is sen -
sitive equipment at the same location, or if the site where the device is installed is close to
either radio or television receivers).
If this is the case, then the operator is obliged to take appropriate action to rectify the situ -
ation.
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 -
ence from the device include:
- Safety devices
- Power, signal and data transfer lines
- IT and telecommunications devices
- Measuring and calibrating devices
Supporting measures for avoidance of EMC problems:
1. Mains supply
- If electromagnetic interference arises despite correct mains connection, addition -
al measures are necessary (e.g. use a suitable line filter).
2. 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
3. Equipotential bonding
4. Earthing of the workpiece
- If necessary, establish an earth connection using suitable capacitors.
5. Shielding, if necessary
- Shield off other nearby devices
- Shield off entire welding installation
