1.0 TECHNICAL DESCRIPTION

1.1

DESCRIPTION

The system consists of a modern direct current generator for the welding of met-
als, 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.

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 IV).
• Exceeding the duty cycle can damage the unit and void the warranty.
1.4

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 IV).

2.0 INSTALLATION

Important: Before connecting, preparing or using equipment, read
section 1.0 SAFETY PRECAUTIONS.
2.1

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.
Check that the power socket is equipped with the fuse indicated in the features
label on the power source. All power source models are designed to compensate
power supply variations. For variations of +-10%, a welding current variation of +-
0.2% is created.

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.
2.3

SELECTING A LOCATION

Special installation may be required where gasoline or volatile
liquids are present. When locating equipment, ensure that the following guide-
lines are followed:
1. The operator must have unobstructed access to controls and equipment
connections.
2. Use rating plate to determine input power needs.
3. Do not position equipment in confined, closed places. Ventilation of the
power source is extremely important. Avoid dusty or dirty locations, where
dust or other objects 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 overturning. Bear in
mind the risk of falling of equipment situated in overhead positions.
2.4

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.
2. Connect the ground cable quick connection to the negative (-) receptacle
and locate the clamp near the welding zone.
3. Connect the electrode cable quick connection to the positive (+) receptacle.
4. Use the above connection for straight polarity welding; for reverse polarity
turn the connection.
5. On the unit preset for coated electrode welding.
6. Adjust welding current with ampere selector. (Rif. 7 - Fig. 1 page 3).
7. Turn on the power source.
2.5 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.
