Make sure that you and others are protected with an adequately insulated, dry base or cov-
er for the earth or ground potential. This base or cover must extend over the entire area
between the body and the earth or ground potential.
All cables and leads must be secured, undamaged, insulated and adequately dimen-
sioned. Replace loose connections and scorched, damaged, or inadequately dimensioned
cables and leads immediately.
Use the handle to ensure the power connections are tight before every use.
In the case of power cables with a bayonet connector, rotate the power cable around the
longitudinal axis by at least 180° and pretension.
Do not wrap cables or leads around the body or parts of the body.
The electrode (rod electrode, tungsten electrode, welding wire, etc.) must

Double the open circuit voltage of a power source can occur between the welding elec-
trodes of two power sources. Touching the potentials of both electrodes at the same time
may be fatal under certain circumstances.
Arrange for the mains cable to be checked regularly by a qualified electrician to ensure the
ground conductor is functioning properly.
Protection class I devices require a mains supply with ground conductor and a connector
system with ground conductor contact for proper operation.
Operation of the device on a mains supply without ground conductor and on a socket with-
out ground conductor contact is only permitted if all national regulations for protective sep-
aration are observed.
Otherwise, this is considered gross negligence. The manufacturer shall not be held liable
for any damage arising from such usage.
If necessary, provide adequate earthing 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 any-
one from plugging the mains plug back in and switching it on again.
After opening the device:

If work on live parts is required, appoint a second person to switch off the main switch at
the right moment.
Meandering weld-
If the following instructions are ignored, meandering welding currents can develop with the

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.
never be immersed in liquid for cooling
Never touch the electrode when the power source is switched on.
Discharge all live components
Ensure that all components in the device are de-energised.

Overheating of parts connected to the workpiece
Irreparable damage to ground conductors
