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, ef-
feciency and energy consumption make it an excellent work tool
suitable for coated electrode and GTAW (TIG) welding.

ACCESSORIES (OPTIONALS)
Consult the area agents or the dealer.
1.4
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
minutes for unit to cool. Reduce amperage, voltage or duty cycle
before starting to weld again (See page V).
1.5
VOLT - AMPERE CURVES
Volt-ampere curves show the maximum voltage and amperage
TIG
output capabilities of the welding power source. Curves of other
settings fall under curves shown (See page V).

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 + 15% a welding current variaton of +- 0,2% is created.
TIG
ON - OFF SWITCH :
This switch has two positions: ON = I and OFF = O.
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 fol-
lowing 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.
