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, effec-
tivity and energy consumption make it an excellent work tool suit-
able 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 tem-
perature that the unit can weld at its rated output without overheat-
ing. If the unit overheats, the output stops and the over
temperature light comes On. To correct the situation, wait fifteen

INSTALLATION

IMPORTANT: BEFORE CONNECTING, PREPARING OR US-
ING 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 varia-
tions of +-10%, a welding current variation of +-0.2% is created.
2.2 CONNECTING THE POWER SOURCE TO THE MO-
TOR-GENERATOR SET
This welder is designed to allow the use of Motor-generator set to
provide an adequate supply for welder during the welding opera-
tions.
Before connecting the welder to the Motor-generator set, make
sure that the following requirements are fulfilled:
1. Output socket of the Motor-generator set allows to connect
the power supply plug of the welder.
2. Output of the Motor-generator set produces alternating sinu-
soidal voltage with nominal RMS value 230 V.
3. Motor-generator set is able to deliver the adequate supply
current / power required for welding operation.
2.3 CONNECTION AND PREPARATION OF EQUIPMENT
FOR STICK WELDING.
• TURN OFF WELDER BEFORE MAKING CONNECTIONS.
CONNECT ALL WELDING ACCESSORIES SECURELY TO
PREVENT POWER LOSS. CAREFULLY FOLLOW 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 terminal (Ref. 6 - Picture 1 Page 4.) 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 - Picture 1 Page 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 NEGA-
TIVE (-) TERMINAL.
4. Adjust welding current with ampere selector (Ref. 2 - Picture
1 Page 4.) .
5. Press the illuminated switch to turn on the power source Ref.
1 - Picture 1 Page 4.) .
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 dis-
ables 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
