2.5 GENERAL NOTES
Before using this welding machine, carefully read the
standards CEI 26/10 CENELEC HD 427 and also check
insulation of cables, electrode holder clamp, sockets and
plugs and that the section and length of welding cables are
compatible with current used:
2
up to 5 m use 16 mm ,
from 5 to 20 m use 25 mm
from 20 to 30 m use 35 mm
WARNING: This equipment does not comply with EN/IEC
61000-3-12. If it is connected to a public low voltage system, it
is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator if
necessary, that the equipment may be connected.
2.6 COATED ELECTRODE WELDING
- Use the electrode holder clamps in compliance with the
safety standards and without projecting tightening screws.
- Make sure that the switch F (picture 1) is in OFF position or
that the plug is not inserted in supply socket then connect
welding cables in accordance with polarity demanded by the
manufacturer of the electrodes which you will be using.
- Welding circuit should not be deliberately placed in direct or
indirect contact with protection wire if not in the piece to be
weld.
- If earthing is deliberately made on the workpiece by means
of the protection wire, the connection must be as direct as
possible, with the wire having a section at least equal to the
welding return current wire and connected to the piece,
Being worked on, in the same place as the return wire, using
the return wire terminal or a second earth terminal close by.
- All possible precautions must be taken in order to avoid
stray currents.
- When taking voltage from a three-phase line, be very

.
careful when connecting the supply cable earth wire to
the socket earth pole.
- Connect the supply cable. When mounting a plug, make
sure that its capacity is adequate and that the yellow-green
wire of the supply cable is connected to the earth plug pin.
- The sections of all extensions should be adequate to
absorbed current I
1
- Turn the machine on by means of the switch F (picture 1).
WARNING: ELECTRIC SHOCK CAN KILL.
- Do not touch live electric parts.
- Do not touch weld output terminals when unit is energized.
- Do not touch electrode holder and earth clamp at the same
time.
- Adjust the current according to the diameter of the electrode,
to the welding position and to the type of joint to be carried
out.
When you have finished to weld, always remember to turn off
the unit and to remove the electrode from the electrode holder.
2.7 TIG WELDING
- This welding machine is fit for welding with TIG procedure:
stainless steel, iron and copper.
- Connect the earth cable wire to the positive (+) pole E (pict.
1) of the welding machine and the terminal to the working
piece as close as possible to the welding machine, making
sure there is a good electrical contact.
- Connect the connector of the TIG torch to the negative (-)
pole D (pict. 1)of the welding machine.
- The welding machine circuit should not be deliberately in
direct or indirect contact with protection conductor if not in
the piece to be welded.
- If earthing is deliberately made on the workpiece by means
of protection wire, the connection must be as direct as
possible, with the wire having a section at least equal to the
welding return current wire and connected to the piece being
worked on, in the same place as the return wire, using the
