Installation and Operator Instructions

Technical description
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. Lt's adjust ability, efficiency and
energy consumption make it an excellent work tool
suitable for coated electrode and GTAW (TIG) welding).
Technical data
The machine can be connected to a motor generator of
power meeting the data plate specifications and having
the following characteristics:

Output voltage between 185 and 275 Vac.

Frequency between 50 and 60 Hz.
IMPORTANT: MAKE SURE THE POWER SOURCE
MEETS THE ABOVE REQUISITES. EXCEEDING THE
SPECIFIED VOLTAGE CAN DAMAGE THE WELDING
MACHINE AND INVALIDATE THE WARRANTY.
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).
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).
Installation
Important: before connecting, preparing
equipment, read safety precautions.
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 + 15% a
welding current variaton of +- 0,2% is created.
BEFORE INSERTING THE MAINS
PLUG, IN ORDER TO AVOID THE
FAIL OF POWER SOURCE, CHECK
IF THE MAINS CORRESPONDS TO
THE WISHED MAIN SUPPLY.

On - off switch: This switch has two positions:
ON = I and OFF = O.
THIS
INTENDED FOR USE IN RESIDENTIAL LOCATIONS
WHERE THE ELECTRICAL POWER IS PROVIDED BY
THE PUBLIC LOW-VOLTAGE SUPPLY SYSTEM.
THERE MAY BE POTENTIAL DIFFICULTIES IN
ENSURING ELECTROMAGNETIC COMPATIBILITY IN
THOSE LOCATIONS, DUE TO CONDUCTED AS WELL
AS RADIATED DISTURBANCES.
