• The 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.
• The 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 ULTRAVIOLET RADIATION is emitted. Therefore
it is vital that his face is also protected from radiation. Ultraviolet rays
produce the same harmful effect as sun burning on unprotected skin.
• The operator is obliged to warn anyone near the welding area of the risks
that welding involves and to arrange to provide adequate protection
equipment.
• 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.
• The operator must ensure all flammable materials are removed from the
work area to avoid any risk of fire.
• The 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. THERE IS A VERY HI H RISK
OF EXPLOSION.
• The operator must be aware of all the special regulations which he needs
to conform to when welding in enclosed spaces with a high risk of
explosion.
• To prevent electric shock, we strongly suggest the following rules:
• Do not work in a damp or humid environment.
• Do not use the welding machine if its cables are damaged in any way.
• Make sure that the earthing system of the electric equipment is correctly
connected and operational.
• The operator must be insulated from the metal components connected to
the return wire.
• The earthing of the piece being worked could increase the risk of injury to
the operator.
• 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 58V.
• 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.
• The open-circuit voltage, for as many adjustments as possible, must never
