LOCATION
Be sure to locate the welder according
to the following guidelines.
•
In areas, free from moisture and dust;
•
Ambient temperature between 0° to 40°C;
•
In areas, free from oil, steam and corrosive
gases;
•
In areas, not subjected to abnormal vibration
or shock;
•
In areas, not exposed to direct sunlight or
rain;
•
Place at a distance of 300mm or more from
walls or similar that could restrict natural air flow
for cooling.
Since the inhalation of welding fumes
can be harmful, ensure that the welding
area is effectively ventilated.
MAIN SUPPLY VOLTAGE REQUIREMENTS
Before you make any electrical connection, check that
supply voltage and frequency available at site are
those stated in the ratings label of your generator.
The main supply voltage should be within ±10% of
the rated main 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 welder Power Source must be:
•
Correctly installed, if necessary, by a qualified
electrician;
•
Correctly grounded (electrically) in accordan-
ce with local regulations;
•
Connected to the correct size electric circuit.
In case the supply cable is not fitted with a plug,
connect a standardized plug (3P+T) to the
cable (in some models the supply cable is supplied
with plug).
To connect the plug to the supply cable, follow these
instructions:
•
the brown (phase) wire must be connected to
the terminal identified by the letter L1
•
the blue or grey wire must be connected to
the terminal identified by the letter L2
•
the black or grey wire must be connected to
the terminal identified by the letter L3
•
the yellow/green (ground) wire must be con-
nected to the terminal identified by the letter
PE or by the symbol
In any case, the connection of the yellow/green wire
to the PE terminal
the event of tearing of the power supply cable from
the plug, the yellow/green wire should be the last
one to be disconnected.
The outlet should be protected by the proper
protection fuses or automatic switches.
INSTALLATION
.
must be done in order that in
Notes:
•
Periodically inspect supply cable for any
cracks or exposed wires. If it is not in good
conditions, have it repaired by a Service Cen-
tre.
•
Do not pull violently the input power cable to
disconnect it from supply.
•
Do not squash the supply cable with other ma-
chines, it could be damaged and cause electric
shock.
•
Keep the supply cable away from heat sorces,
oils, solvents or sharp edges.
•
In case you are using an extension cord, try to
keep it well straight and avoid its heating up.
SAFETY INSTRUCTIONS
For your safety, before connecting the power source
to the line, closely follow these instructions:
•
An adequate switch must be inserted before
the mains outlet; this switch must be equip-
ped with time-delay fuses;
•
The connection with ground must be made
with a plug compatible with the above men-
tioned socket;
•
When working in a confined space, the power
source must be kept outside the welding area
and the ground cable should be fixed to the
workpiece. Never work in a damp or wet area,
in these conditions.
•
Do not use damaged input or welding cables
•
The welding torch should never be pointed at
the operator's or at other persons' body;
•
The power source must never be operated
without its panels; this could cause serious
injury to the operator and could damage the
equipment.
