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, efficiency and energy consumption make it
an excellent work tool suitable for coated electrode and GTAW (TIG) weld-
ing.
2.0 TECHNICAL SPECIFICATIONS
DATA PLATE
2.1
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).
2.2
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 SAFETY PRECAUTIONS.
3.1
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 +-10%, a welding current variation of +-
0.2% is created.
ON - OFF SWITCH:
This switch has two positions:
ON
and
OFF
.
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
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.
3.4
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 regulations.
1.
Fit the selected electrode to the electrode clamp.
2.
Connect the earth lead connector to the negative
(-)
quick-connection ter-
minal (-)
Ref. 6
- Fig. 1 page 3) and the earth clamp of the workpiece near
the welding zone.
3.
Connect the electrode clamp connector to the positive
(+)
quick-connection
terminal (+)
Ref. 5
- Fig. 1 page 3) .
4.
CAUTION:
Make the above connection for
direct polarity welding
; for
inverse polar-
ity
, invert the connection:
earth lead CONNECTOR to the quick-connection
positive (+) terminal and the electrode holder clamp connector to the
negative (-) terminal.
5.
Adjust welding current with ampere selector
