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.

1.3 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).
1.4 VOLT - AMPERE CURVES
Volt-ampere curves show the maximum voltage and amperage output capa-
bilities of the welding power source. Curves of other settings fall under
curves shown (See page III).
2.0 INSTALLATION
IMPORTANT: Before connecting, preparing or using equipment.
Read SAFETY PRECAUTIONS.
2.1 CONNECTING THE POWER SOURCE TO THE MAINS ELECTRICITY SUP-
PLY.
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 +-20%, a welding current variation of +-
0.2% is created.

ON - OFF SWITCH:
This switch has two positions: ON = I and OFF = O.
TIG The welder is designed to be worked from a generator.
Before connecting the welder to the generator it is important to establish that the
generator has the following technical requirement:
a. the 230V 50/60 Hz socket can supply sufficient power required for welding,
see label on welder.
b. the socket supplies undistorted voltage RMS between 180 and 280 V.
c. the socket supplies peak voltage between 230 and 420 V.
TIG
d. the socket supplies alternate voltage with a frequency between 50 and 60
Hz.
It is advisable to follow the above instructions otherwise the welder could be
damaged.
2.2 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.
2.3 SELECTING A LOCATION
Special installation may be required where gasoline or volatile
liquids are present.
When locating equipment, ensure that the following guidelines 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. Care-
fully follow safety precautions.

BEFORE INSERTING THE MAINS PLUG, IN OR-
DER TO AVOID THE FAIL OF POWER SOURCE,
CHECK IF THE MAINS CORRESPONDS TO THE
WISHED MAIN SUPPLY.
