INSTRUCTION MANUAL FOR ARC WELDING MACHINE

IMPORTANT
Before using this device all people authorised to its use, repair
or inspection, should read the book "Safety rules for using
machines" and the "Instruction manual" specific for every
machine. Contact your distributor if you have not understood
some instructions.
Remember: YOUR SAFETY DEPENDS ON YOU!!!
Follow all safety rules and instructions.
It is your job to protect yourselves and others against the risks
related to welding.
The operator is responsible for his own safety and the safety of
others in the work area. He must therefore know and obey all
safety rules.
NOTHING CAN REPLACE GOOD COMMON SENSE!!!

IP21 .......... Grade of protection of frame.
Grade 1 as a second number means that
this unit is not fit to work outside under the
rain.
NOTES: In addition, the welding machine has been designed to
work in areas with grade 3 of pollution (see IEC 664).
1.2 SPECIFICATIONS
This manual has been prepared in order to instruct the
personnel assigned to the installation, to the use and to the
repair or control of the arc welding machine. This welder is an
alternate current generator designed for welding with rutile
coated electrodes.
For any requests of information, please always state the item
and the serial number of the welding machine.
1.3 BEFORE CONNECTING THE WELDING MACHINE
Before connecting and switching on the unit follow all safety
rules and instructions as indicated in this manual. Make sure
that the air flow on cooling slots is not obstructed and then
proceed as follows:
1) unpack the machine
2) take care that the unit is not placed against a wall or in a
position which might cut off the air; moreover, do not
cover the unit's source with plastic materials, metal or paper
sheets because they cause the decrease of the airflow,
3) make sure that the air temperature does not exceed +40°C,
4) do not place any filtering device over the intake air passages
of this welding machine.
Warranty is void if any type of filtering device is used.
2 INSTALLATION
2.1 CONNECTION TO MAINS SUPPLY
Before connecting the unit to the mains power, make sure that
mains voltage corresponds to the voltage of the welding
machine.
As regards the welding machines with two input voltages (i.e.
230/400V or 240/415V etc.), voltage can be changed by
removing the switch knob (pos. 2 picture 2), after unscrewing
(pos. 1 picture 2) and by properly setting the disc under the
knob, after over - turning it (pos. 3 picture 2).
For the connection of a single-phase welding machine a 2x16A
+ Ground plug is required. The yellow-green lead is the
protection wire which is connected to the casing of the machine
and is to be introduced into the ground pin of the plug. The
mains system must be properly grounded and provided with
suitable leads and protections, according to the regulations in
force.
The required power ranges from 2.5 to 4.5 kW depending on
the intensity of the current used.
