SECTION 3:
INSTALLATION
3.01 Environment
These units are not designed for use in environments
with increased hazard of electric shock.
A. Examples of environments with increased hazard
of electric shock are:
. In locations in which freedom of movement
is restricted, so that the operator is forced to
perform the work in a cramped (kneeling, sit-
ting or lying) position with physical contact with
conductive parts;
2. In locations which are fully or partially limited
by conductive elements, and in which there is
a high risk of unavoidable or accidental contact
by the operator, or
3. In wet or damp hot locations where humidity
or perspiration considerable 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 conduc-
tive parts in the near vicinity of the operator, which
can cause increased hazard, have been insulated.
3.02 Location
Be sure to locate the welder according to the follow-
ing guidelines:
. In areas, free from moisture and dust.
2. Ambient temperature between 0ºC to 40ºC.
3. In areas, free from oil, steam and corrosive
gases.
4. In areas, not subjected to abnormal vibration or
shock.
5. In areas, not exposed to direct sunlight or
rain.
6. Place at a distance of 300mm or more from walls
or similar that could restrict natural air flow for
cooling.
3.03 Ventilation
Since the inhalation of welding fumes can be harmful,
ensure that the welding area is effectively ventilated.
3.04 Mains Supply Voltage
Requirements
The Mains supply voltage should be within 0% of
the rated Mains supply voltage. Too low a voltage
may cause poor welding performance. Too high a
supply voltage will cause components to overheat
and possibly fail.
The Welding Power Source must be:
• Correctly installed, if necessary, by a qualified
electrician.
• Correctly earthed (electrically) in accordance
with local regulations.
• Connected to the correct size power point and
fuse for each Power Source as per the Specifica-
tions on pages 2-4 and 2-5.
The WeldSkill 250 MIG Power Source is supplied with
a 20 Amp input lead and is designed for a 240 VAC
supply voltage.

Welding Power Source is used in a do-
mestic situation.
3.05 Installation and Users
Responsibility
The user is responsible for installing and using the
welding equipment according to the manufacturer’s
instructions. If electromagnetic disturbances are
