at the interface with the public grid
see "Technical data"
In this case, the plant operator or the person using the device should check whether the
device may be connected, where appropriate by discussing the matter with the power
supply company.
IMPORTANT! Ensure that the mains connection is earthed properly
Protecting
Anyone working with the device exposes themselves to numerous risks, e.g.
yourself and
-
others
-
-
-
-
-
Suitable protective clothing must be worn when working with the device. The protective
clothing must have the following properties:
-

Protective clothing refers to a variety of different items. Operators should:
-
-
-
-
-
Keep all persons, especially children, out of the working area while any devices are in
operation or welding is in progress. If, however, there are people in the vicinity:

Noise emission
The device generates a maximum sound power level of <80 dB(A) (ref. 1pW) when idling
values
and in the cooling phase following operation at the maximum permissible operating point
under maximum rated load conditions according to EN 60974-1.
It is not possible to provide a workplace-related emission value during welding (or cut-
ting) as this is influenced by both the process and the environment. All manner of diffe-
rent welding parameters come into play, including the welding process (MIG/MAG, TIG
welding), the type of power selected (DC or AC), the power range, the type of weld
metal, the resonance characteristics of the workpiece, the workplace environment, etc.
Connection restrictions
Criteria with regard to the maximum permissible mains impedance
Criteria with regard to the minimum short-circuit power requirement
flying sparks and hot pieces of metal
Arc radiation, which can damage eyes and skin
Hazardous electromagnetic fields, which can endanger the lives of those using car-
diac pacemakers
Risk of electrocution from mains current and welding current
Greater noise pollution
Harmful welding fumes and gases
Flame-resistant
Insulating and dry
Covers the whole body, is undamaged and in good condition
Safety helmet
Trousers with no turn-ups
Protect eyes and face from UV rays, heat and sparks using a protective visor and
regulation filter
Wear regulation protective goggles with side protection behind the protective visor
Wear stout footwear that provides insulation even in wet conditions
Protect the hands with suitable gloves (electrically insulated and providing protection
against heat)
Wear ear protection to reduce the harmful effects of noise and to prevent injury
Make them aware of all the dangers (risk of dazzling by the arc, injury from flying
sparks, harmful welding fumes, noise, possible risks from mains current and welding
current, etc.)
Provide suitable protective equipment
Alternatively, erect suitable safety screens/curtains.
