3.03 Environment
These units are designed for use in environments with
increased hazard of electric shock as outlined in IEC
60974-5.
A. Examples of environments with increased hazard of
electric shock are:
1. In locations in which freedom of movement is re-
stricted, so that the operator is forced to perform the
work in a cramped (kneeling, sitting or lying) position
with physical contact with conductive parts.
2. In locations which are fully or partially limited by con-
ductive elements, and in which there is a high risk of
unavoidable or accidental contact by the operator.
3. In wet or damp hot locations where humidity or per-
spiration considerably reduces the skin resistance
of the human body and the insulation properties of
accessories.
B. Environments with increased hazard of electric shock
do not include places where electrically conductive parts in
the near vicinity of the operator, which can cause increased
hazard, have been insulated.
3.04 Location
Be sure to locate the wirefeeder according to the follow-
ing guidelines:
A. In areas, free from moisture and dust.
B. Ambient temperature between 0° C to 40° C.
C. In areas, free from oil, steam and corrosive gases.
D. In areas, not subjected to abnormal vibration or shock.
E. In areas, not exposed to direct sunlight or rain.
F. The enclosure design of this Wire Feeder meets the
requirements of IP23S as outlined in IEC 60529. This
provides adequate protection against solid objects
(greater than 1/2", 12mm), and direct protection from
vertical drops. Under no circumstances should the unit
be operated or connected in a micro environment that
will exceed the stated conditions. For further informa-
tion please refer to IEC 60529.
G. Precautions must be taken against the Wire Feeder
toppling over. The Wire Feeder must be located on
a suitable horizontal surface in the upright position
when in use.
3.05 Ventilation
!
WARNING
Since the inhalation of welding fumes can be
harmful, ensure that the welding area is ef-
fectively ventilated.
3.06 Mains Supply Voltage
Requirements
CAUTION
This wirefeeder cannot be connected directly
to the mains supply. It must be connected
to a suitable wirefeeder control socket on a
power source.
3.07 Electromagnetic Compatibility
!
WARNING
Extra precautions for Electromagnetic Com-
patibility may be required when this Welding
Power Source is used in a domestic situation.
A. Installation and Use - Users Responsibility
The user is responsible for installing and using the welding
equipment according to the manufacturer’s instructions.
If electromagnetic disturbances are detected then it shall
be the responsibility of the user of the welding equipment
to resolve the situation with the technical assistance of
the manufacturer. In some cases this remedial action
may be as simple as earthing the welding circuit, see
NOTE below. In other cases it could involve constructing
an electromagnetic screen enclosing the Welding Power
Source and the work, complete with associated input
filters. In all cases, electromagnetic disturbances shall be
reduced to the point where they are no longer Trouble-
some.
NOTE
The welding circuit may or may not be earthed
for safety reasons. Changing the earthing ar-
rangements should only be authorized by a
person who is competent to assess whether
the changes will increase the risk of injury,
e.g. by allowing parallel welding current return
paths which may damage the earth circuits of
other equipment. Further guidance is given in
IEC 60974-10 Arc Welding Equipment - Instal-
lation and use (under preparation).
