Ensure suitable personal protection with dry temporary backing or cover with sufficient
insulation against the ground potential. The temporary backing or cover must completely
cover the entire area between the body and the ground potential.
All cables and leads must be secured, undamaged, insulated, and adequately dimen-
sioned. Replace loose connections and scorched, damaged, or inadequately dimen-
sioned cables and leads immediately.
Before every use, check power connections for secure fit by hand.
In the case of power cables with bayonet connectors, turn the power cable by at least
180° around the longitudinal axis and pretension.
Do not wrap cables or leads around your body or parts of the body.
Concerning the electrode (rod electrode, tungsten electrode, welding wire, etc.)
-
Never immerse it in liquids to cool it
- Never touch it when the power source is switched on.
The open circuit voltage of a welding system may double, for example, between the elec-
trodes of two welding systems. Touching the potentials of both electrodes at the same
time may be life-threatening in some cases.
Have the grid and device supply lead regularly inspected by an electrician to ensure that
the ground conductor is functioning properly.
Protection class I devices require a grid with a ground conductor and a connector system
with ground conductor contact for proper operation.
Operation of the device on a grid without a ground conductor and on a socket without a
ground conductor contact is only permitted if all national regulations for protective separ-
ation are observed.
Otherwise, this is considered gross negligence. The manufacturer accepts no liability for
any damage resulting from improper use.
Use suitable equipment to ensure that the workpiece is sufficiently grounded if neces-
sary.
Switch off unused devices.
When working at elevated heights, wear a safety harness to prevent falls.
Before working on the device, switch off the device and remove the grid plug.
Secure the device to prevent the grid plug from being connected and switched on again
by applying a clearly legible and understandable warning sign.
After opening the device:
-
Discharge all electrically charged components
- Ensure that all components are disconnected from the power supply.
If work is needed on voltage-carrying parts, bring in a second person who will switch off
the main switch at the correct time.
Stray welding
currents If the following instructions are not observed, stray welding currents may occur, which
pose a risk of the following:
-
Fire
- Overheating of components connected to the workpiece
- Destruction of ground conductors
- Damage to the device and other electrical equipment
Ensure that the workpiece terminal is securely connected to the workpiece.
Secure the workpiece terminal as close to the spot to be welded as possible.
