EMC Device Clas-
sifications
10
To comply with European Directive 2006/66/EC on Batteries and Accumula-
tors and its implementation in national law, batteries and rechargeable batter-
ies that have reached the end of their life must be collected separately and
returned to an approved recycling facility. Be sure to return any device that you
no longer require to your dealer, or find out about the approved collection and
recycling facilities in your area. Ignoring this European Directive may be harm-
ful to the environment and your own health!
Devices with mechanically undamaged rechargeable batteries may be re-
turned to the relevant Fronius Service Partner for repair or battery replace-
ment.
As soon as it becomes evident that the rechargeable battery has been me-
chanically damaged (e.g. electrolyte is escaping), dispose of the device at
your nearest recycling centre in accordance with national laws and guidelines.
If anything is unclear or you have any questions about disposal, contact your
Fronius Service Partner.
If the following instructions are ignored, meandering welding currents can de-
velop 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 weld-
ed.
If the floor is electrically conductive, the device must be set up with sufficient
insulating material to insulate it from the floor.
If distribution boards, twin-head mounts, etc., are being used, note the follow-
ing: The electrode 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.
Devices in emission class A:
- Are only designed for use in industrial settings
- Can cause line-bound and radiated interference in other areas
Devices in emission class B:
- Satisfy the emissions criteria for residential and industrial areas.
This is also true for residential areas in which the energy is sup-
plied from the public low-voltage mains.
