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
in 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 equip-
ped with time-delay fuses;
•
The connection with ground must be made with a two-pole 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.
3.0
This manual was edited to give some indications on the operation of the welder and was thought to offer
information for its practical and safe use. Its purpose is not to teach welding techniques. All suggestions
are indicative and intended to be only guide lines.
To ensure that your welder is in good conditions, inspect it carefully when you remove it from its packing
having care to ascertain that the cabinet or the stocked accessories are not damaged.
Your welder is capable of daily activity metal fabrication and maintenance. Its simplicity and versatility
and its excellent welding characteristic are the product of the most up to date inverter technology. This
welding inverter offers the welder the ability to create precise arc characteristics and at the same time
reduce consumption of energy with respect to the welders based on a traditional transformer.
Respect the duty cycle of the welder making reference to the technical data label on the welder's back.
Duty cycle is given as percentage on a 10 minute time. During this period of time the unit can be used
at the rated duty cycle. Exceeding the rated duty cycle may cause overheating or welder damage.
