closed and well fixed.

10. Do not expose the welding machine to direct sunlight or to heavy rain.

his equipment conforms to protection rating IP23S.

11. During welding, the welding cables must be located near or at ground

level. hey should be as short as possible.

12. he operator must wear gloves, clothes, shoes, and a helmet or a

welder’s helmet, which protect and are fire-resistant in order to protect him

against electric shock, flashes and sparks from welding.

13. he operator must protect his eyes with safety visor or mask designed for

welding, fitted with standard safety filters. He should also be aware that

during electrical welding UL RAVIOLE RADIA ION is emitted. herefore it

is vital that his face is also protected from radiation. Ultraviolet rays produce

the same harmful effect as sun burning on unprotected skin.

14. he operator is obliged to warn anyone near the welding area of the risks

that welding involves and to arrange to provide adequate protection

equipment.

15. It is very important to arrange for sufficient ventilation, especially when

welding in enclosed spaces. We suggest using suitable fume extractors to

prevent the risk of intoxication by fumes or gas generated by the welding

process.

16. he operator must ensure all flammable materials are removed from the

work area to avoid any risk of fire.

17. he operator must NEVER weld containers that have previously

contained petrol, lubricants, gas or similar flammable materials, even if the

container has been empty for a considerable time. HERE IS A VERY

HIGH RISK OF EXPLOSION.

the return wire.

24. he 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 50,9 V.

26. he 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. hese values are not applicable to the strike

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

27. he 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
