1.0 TECHNICAL DESCRIPTION

1.1 DESCRIPTION
The system consists of a modern direct current generator for the welding of
metals, developed via application of the inverter. This special technology allows
for the construction of compact light weight generators with high performance.
l'ts adjust ability, effeciency and energy consumption make it an excellent work
tool suitable for coated electrode and GTAW (TIG) welding.

IMPORTANT: Make sure the power source meets the above requisites. Exceed-
ing the specified voltage can damage the welding machine and invalidate the
warranty.
2.1 ACCESSORIES
Consult the area agents or the dealer.
2.2 DUTY CYCLE AND OVERHEATING
Duty cycle is the percentage of 10 minutes at 40°C ambient temperature that the
unit can weld at its rated output without overheating. If the unit overheats, the out-
put stops and the over temperature light comes On. To correct the situation, wait
fifteen minutes for unit to cool. Reduce amperage, voltage or duty cycle before
starting to weld again (See page III).
2.3 VOLT - AMPERE CURVES
Volt-ampere curves show the maximum voltage and amperage output capabilities
of the welding power source. Curves of other settings fall under curves shown
(See page III).
3.0 INSTALLATION
IMPORTANT: Before connecting, preparing or using equipment,
read section 1.0 SAFETY PRECAUTIONS.
3.1 CONNECTING THE POWER SOURCE TO THE MAINS ELECTRICITY SUPPLY.
Serious damage to the equipment may result if the power source is
switched off during welding operations.
The equipment is shipped without any plug installed. It works with a wide range of

ORDER TO AVOID THE FAIL OF POWER
SOURCE, CHECK IF THE MAINS CORRE-

ON - OFF SWITCH
This switch has two positions: ON = I and OFF = O.
3.2 HANDLING AND TRANSPORTING THE POWER SOURCE
OPERATOR SAFETY:
Welder's helmet - Glowes - Shoes with high insteps.
The welding power source do not weight more than 25 Kg and
can be handled by the operator. Read well the following precautions.
The machine is easy to lift, transport and handle, though the following procedures
must always be observed:
1. The operations mentioned above can be operated by the handle on the
power source.
2. Always disconnect the power source and accessories from main supply
before lifting or handling operations.
3. Do not drag, pull or lift equipment by the cables.
3.3 CONNECTION AND PREPARATION OF EQUIPMENT FOR STICK WELDING.
• TURN OFF WELDER BEFORE MAKING CONNECTIONS.
Connect all welding accessories securely to prevent power loss. Carefully fol-
low safety precautions described in section 1.0
1. Fit the selected electrode to the electrode clamp.
Connect the ground cable quick connection to the negative (-) receptacle
2.
and locate the clamp near the welding zone.
Connect the electrode cable quick connection to the positive (+) receptacle.
3.
4. Use the above connection for straight polarity welding; for reverse polarity
turn the connection.
5. On the unit preset for coated electrode welding (Rif.5 - Fig. 1
page 3)
Adjust welding current with ampere selector. (Rif.3 - Fig. 1
6.
page 3) .
7. Turn on the power source.
3.4 CONNECTION AND PREPARATION OF EQUIPMENT FOR GAS TUNGSTEN
ARC WELDING (TIG).
• TURN OFF WELDER BEFORE MAKING CONNECTIONS.
Connect welding accessories securely to avoid power loss or leakage of dan-
gerous gases. Carefully follow the safety precautions described in section 1.0.
1. Fit the required electrode and nozzle to the electrode holder (Check the pro-
trusion and state of the electrode tip).
Connect the ground cable quick connection to the positive (+) receptacle
2.
and the clamp near the welding zone.
3. Connect the electrode torch power cable connector to the negative quick-
connection terminal (-) and the torch push button connector to the corre-
sponding socket (Rif.10 - Fig. 1 page 3) .
CAUTION: THE EARTH CABLE CONNECTOR AND THE TORCH POWER CABLE
CONNECTED AS ABOVE WILL RESULT IN STRAIGHT POLARITY WELDING. THIS
GENERATOR IS NOT SUITABLE FOR GTAW (TIG) WELDING WITH REVERSE
POLARITY.
