THIS WELDER MUST NOT BE CONNECTED
TO AN CURRENT GENERATING SET.

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
output 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 capabilities
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
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.
2.2 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 regulations described in SAFETY RULES.
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 polarity, 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 Ref. 2 - Fig. 1 page 3) .
6. Press the illuminated switch to turn on the power source Ref. 1 - Fig. 1
page 3) .
N.B. Serious damage to the equipment may result if the power source is
switched off during welding operations.
The power source is fitted with an anti-sticking device that disables power if
output short circuiting occurs or if the electrode sticks, allowing it to be easily
detached from the workpiece.
This device enters into operation when power is supplied to the generator, even
during the initial checking period, therefore any load input or short circuit that
occurs during this phase is treated as a fault and will cause the output power to be
disabled.
2.3 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 dange-
rous gases. Carefully follow the safety regulations.
1. Fit the required electrode and nozzle to the electrode holder (check the pro-
trusion and state of the electrode tip).
2. Connect the earth lead connector to the positive (+) quick-connect terminal
Ref. 5 - Fig. 1 page 3) and the earth clamp to the workpiece near the wel-
ding zone.
3. Connect the torch lead connector to quick-connection negative (-) terminal
Ref. 6 - Fig. 1 page 3) .
4. Connect the torch gas hose to the gas cylinder outlet.
5. Press the illuminated switch to turn on the power source Ref. 1 - Fig. 1
page 3) .
6. Check that there are no gas leaks.
7. Adjust welding current with ampere selector Ref. 2 - Fig. 1 page 3) .
Check gas delivery; turn gas cylinder knob to regulate flow .
NB: The electric welding arc is struck by lightly touching the workpiece with the
electrode (Scratch start).
CAUTION: When working outdoors or in windy conditions protect the flow of
shielding gas or it may be dispersed with resulting lack of protection for the
weld.
