possible anomalies that should be noticed. Possible damages on the outer package should arise some doubts on the
integrity of its content. Remove the package and visually verify the welder integrity. Check that the welder is equipped
with all the standard components; immediately inform the manufacturer in case some components should lack. All the
material forming the package must be removed according to the present environmental protection regulations.
INSTALLATION
The welder must be installed in a position fulfilling the following features:
Indoor: the use of the welder out of doors is not foreseen.
Room temperature between 0 and 40 °C; 1000 m. maximum altitudes.
In a well-ventilated area, free from dust, steam, and acid fume.
The working place must be free from inflammable materials because the working process can produce sparks of
melted metal.
In a place with a suitable lighting system in comparison with the work to be carried out.
The place of installation must be flat and the ground must be without unevenness that can be dangerous when
working.
If the welder is used to carry out welding processes which can cause fumes, there must be installed a proper
fume extractor.
ELECTRICAL INSTALLATION
First check that the machine is of the right class in comparison with the working environment.
Warning: resistance-welding equipment in this manual are not intended to be used on a low-voltage public network that
supplies domestic premises. It may cause radio frequency interference.
Specialised personnel, aware of all safety rules must carry out installation. This unit can be supplied for different power
supply versions. Before connecting the unit to the power line, check if the voltage shown on the features plate
corresponds to the one of your power supply.
Consult the "technical features" table on the machine to determine the cables section to be used, according to their
length. The fuses that must be placed on the welder supply input must be delayed types. In order to facilitate the
maintenance, we recommend you supply the welder by means of a breaker switch. The welder has not been designed for
multiple voltages supply. If a voltage change is necessary consult your supplier.
PNEUMATIC INSTALLATION
For a correct compressed air supply to the welder, it is necessary either a centralised system or a compressor capable of
supplying dry air cooled within the pressure limits (3÷8 Bar).
In case the line is subject to great pressure variations, it is advisable to supply the welder by means of a tank of at least
25 litres equipped with a gauge-pressure supplied by means of a one-way valve.
The machine is equipped with a filter unit, the moisture of which must be discharged periodically.
SAFETY RULES
For a safe welder operation, specialised personnel following all the instructions stated on the «INSTALLATION»
paragraph must carry out the installation.
Following all the safety instructions stated on the «MAINTENANCE» chapter must carefully carry out the welder
maintenance. In particular, notice that the electrodes maintenance must be carried out with the welder switched off.
Only trained personnel should operate the welder; in any case, users operating the welder must be aware of the possible
risks and must have both read and understood this manual.
Only authorised personnel can carry out the welder adjustments. The welder adjustments affect the operative safety so
much so that only qualified personnel must carry them out.
Carefully follow the instruction stated on the "WORKING PROCESS" chapter.
It is forbidden to have more people working on the welder at the same time.
No admittance allowed to the working area to people other than the operator.
The welder main risk is the squashing of the hands caused by the moving of arms and electrodes, etc. For
this reason, it is necessary to pay great attention and to follow all the instructions stated on this manual. In particular:
▪
Avoid working with the hands nearby the welder mobile components
▪
Use pliers or tools allowing the positioning of the pieces by keeping the hands far from the electrodes.
The supply of the pneumatic gun is performed by means of a normally closed solenoid valve. The mains switch, in order
to avoid accidental risks due to lack of electricity, but not to lack of pneumatic supply controls it.
Notice that this type of machines generates strong magnetic fields attracting metals and damaging
watches, magnetic cards and magnetic data storage media. Since these magnetic fields can affect pacemakers,
the wearers must consult their doctor before approaching to the welding area. The personnel must wear both
