20.

Do not work in a damp or humid environment.

21.

Do not use the welding machine if its cables are damaged in any way.

22.

Make sure that the earthing system of the electric equipment is correctly

connected and operational.

23.

The operator must be insulated from the metal components connected to

the return wire.

24.

The earthing of the piece being worked could increase the risk of injury to

the operator.

25.

EN 60974-1 Standard: Open-circuit voltage. During the operation of the

machine, the highest voltage, with which it is possible to come into contact, is

the open-circuit voltage between the welding clamps. In our generator this

voltage is 61V respective 65 V.

26.

The maximum open-circuit voltage of the welding machines is established

by national and international standards (EN 60974-1) depending on the type

of weld current to be used, on its waveform and on the hazards arising from

the work place. These values are not applicable to the strike currents and

those for stabilisation of the arc that could be above it.

27.

The open-circuit voltage, for as many adjustments as possible, must never

exceed the values relating to the various cases shown in the following table:

Case Working conditions

Places with increased risk of

electric shock

Places without increased risk

of electric shock

Torches held mechanically

with increased protection for

the operator

28.

In case 1, the dc welding machines with rectifier must be built in such a

way that, in case of a fault developing in the rectifier (for example open circuit,

short circuit or lack of power), the permitted values cannot be exceeded. The

welding machines of this type can be marked with the symbol:

29.

Before opening the machine switch off the machine and disconnect it from

the power socket.

30.

Only personnel authorised by this company can carry out maintenance on

the machine.

NOTE:

Device complies with IEC 61000-3-12.
