Meandering weld-
ing currents
Arrange for the mains and device supply to be checked regularly by a qualified
electrician to ensure the PE conductor is functioning properly.
The device must only be operated on a mains supply with a PE conductor and
a socket with an earth contact.
If the device is operated on a mains without a PE conductor and in a socket
without an earth contact, this will be deemed gross negligence. The manufac-
turer shall not be liable for any damage resulting from such improper use.
If necessary, provide an adequate earth connection for the workpiece.
Switch off unused devices.
Wear a safety harness if working at height.
Before working on the device, switch it off and pull out the mains plug.
Attach a clearly legible and easy-to-understand warning sign to the device to
prevent anyone from reconnecting it to the mains and switching it on again.
After opening the device:
-
discharge all components holding an electric charge
- ensure that all components in the device are de-energised.
If work on live parts cannot be avoided, appoint a second person to switch off
the main switch at the right moment.
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 PE 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.
In the case of automated MIG/MAG applications, ensure that only an insulated
wire electrode is routed from the welding wire drum, large wirefeeder spool or
wirespool to the wire-feed unit.
