TECHNICAL DESCRIPTION

1.1 DESCRIPTION
The system is a modern direct current generator for plasma arc
cutting, created thanks to the application of the inverter. This spe-
cial technology allows for the construction of compact, light weight
generators with high performance. Possibility of adjustment, high
efficiency and reduced power consumption make it an excellent
tool, able to execute quality cutting up to thicknesses of 10 mm.
The generator uses compressed air as a gas, which can be supplied
by a normal compressor or a centralized system of adequate size.
The generator is equipped with automatic arc restart, which en-
ables optimum cutting of metal grid structures. The generator also
features safety systems that inhibit the power circuit when the op-
erator comes into contact with live parts of the machine. Cutting of
thicknesses up to 1 mm with just the pilot arc is also possible; this
is very useful with painted metals to which the positive pincer can-
not be connected.
WARNING: DURING WORKING TIME, DUE TO THE HUMIDITY
OF AIR, IT IS POSSIBLE TO HAVE EMISSION OF WATER
FROM THE TORCH. THIS ISN'T A DEFECT AND NOT REDUCE
THE QUALITY OF CUT NETHER THE LIFE OF WEAR PARTS.

1.4 DUTY CYCLE
The duty cycle is the percentage of 10 minutes that the power
source can cut at its rated current, considering an ambient tem-
perature of 40° C, without the thermostatic protector cutting in. If
it does cut in, the user has to wait for power source reinstatement
before resuming cutting (see page III).
DO NOT EXCEED THE MAXIMUM WORK CYCLE. EXCEED-
ING THE WORK CYCLE SPECIFIED ON THE DATAPLATE
CAN DAMAGE THE POWER SOURCE AND INVALIDATE THE
WARRANTY.
2.0 INSTALLATION
IMPORTANT: BEFORE CONNECTING, PREPARING OR US-
ING EQUIPMENT, READ SECTION SAFETY PRECAUTIONS.
2.1 CONNECTING THE POWER SOURCE TO THE MAINS
ELECTRICITY SUPPLY.
Check that the power socket is equipped with the fuse indicated in the
technical data table on the power source. All power source models

2.2 POWER SOURCE POSITIONING
SPECIAL INSTALLATION MAY BE REQUIRED WHERE GAS-
OLINE OR VOLATILE LIQUIDS ARE PRESENT. CONTACT
THE COMPETENT AUTHORITIES. WHEN POSITIONING
EQUIPMENT, ENSURE THAT THE FOLLOWING GUIDELINES
ARE FOLLOWED:
1. The operator must have unobstructed access to controls and
equipment connections.
2. Check that the power cable and fuse of the socket for power
source connection is suited to current requirements of the latter.
3. Do not position equipment in confined, closed places. Venti-
lation of the power source is extremely important. Avoid
dusty or dirty locations, where dust or other debris could be
aspirated by the system.
4. Equipment (including connecting leads) must not obstruct
corridors or work activities of other personnel.
5. Position the power source securely to avoid falling or over-
turning. Bear in mind the risk of falling of equipment situated
in overhead positions.
2.3 HANDLING AND TRANSPORTING THE POWER
SOURCE
OPERATOR PROTECTION: WELDER'S HELMET - GLOVES -
SAFETY SHOES - GAITERS.
THE CUTTING POWER SOURCE DOES NOT WEIGH MORE
THAN 25 KG AND CAN BE HANDLED BY THE OPERATOR.
READ THE FOLLOWING PRECAUTIONS CAREFULLY.
The power source has been designed for lifting and transport.
However, the following procedures must always be observed:
1. The operations mentioned above can be carried out by
means of the handle on the power source.
2. Disconnect the power source from the power supply and all
accessories before liftling or moving. Do not drag, pull or lift
equipment by the cables.
3. Do not drag, pull or lift equipment by the cables.
