INSTALLATION RECOMMENDATIONS
2.1 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.
2.2 VENTILATION
Since the inhalation of welding fumes can be harmful, ensure that the welding area is effectively ventilated.
2.3 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 accordance 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 (2P+T) to the
(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 L
•
the blue (neutral) wire must be connected to the terminal identified by the letter N
•
the yellow/green (ground) wire must be connected 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.
Notes:
•
Periodically inspect supply cable for any cracks or exposed wires. If it is not in good conditions, have
it repaired by a Service Centre.
•
Do not pull violently the input power cable to disconnect it from supply.
•
Do not squash the supply cable with other machines, 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.
2.4 SAFETY INSTRUCTIONS
For your safety, before connecting the power source to the line, closely follow these instructions:
•
An adequate two-pole switch must be inserted before the main outlet; this switch must be equipped
with time-delay fuses;
•
The connection with ground must be made with a two-pole plug compatible with the above mentio-
ned 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.
