MAINS CONNECTION
Before making any electrical
connection check that the mains
voltage ratings of the data table
correspond with the voltage of the
workplace.
The machine is to be fed with
two conductors 2 phases or
phaseneutral plus a third separate
one designed for the protective
earth connection (PE);
This conductor is coloured yellow/
green. For welders with doubles
voltage supply, it is necessary to set
the blocking screw wfthe voltage-
reverse switch in the position crre
sponding to the voltage really
available (see exampli below).
Connect to the mains cable a
standardized plug of adequate
capacity (2p + t) and set a
standardized plug equipped with
fuses or an auto matic switch.
Set a standardized plug equipped
with fuses or an automtic switch
the correct terminal is to be
connected to the ground conductor
(yellow green) of the mains voitage
suppiy.
Table 1 shows the recommended
ampere values of delayed type fuses
selected accordins to maximum
nominal mains currrnt of welder and
nominal mains voltage
WELDING ACCESSORIES
CONNECTIONS AND THEIR
APPLICATION
WORK CABLE
This must be dire ptly connected to
the norkpieca or the work bench
WARNING! make sure contact to
norkpiece is adequate by avoiding
varnished surfaces and/or non-
metailic materials N.B.
For welders with clamp this cable
must be connected to the clamp
with this symbol.
COLLET CABLE
This has a special clamp on the
terminal to attach to the exposed
part of the electrode N.B.
For welders with clamp this cable
must be connected to the clamp
with this symbol.
PROTECTIVE MASK
This must ALWAYS be used during
welding to protect the eyes from
the light radiation produced by the
are . The mask allows observation
of the welding being carried out.
1 - Maske; 2 - Glass;
3 - Filter (DIN 9-10); 4 - Handgriff;
EXECUTION OF WELD
After carrying out all electrical
conneonsne nessassry both on
mains and welding circuits proceed
in the following way.
Insert the exposed part of the
electrode into the collet and
connect the work clamp to the
welding piece taking care that
electric contact is good.
Turn on welder and regulate
welding current (with knob (1)) In
function of the electrode in use.
Holding the mask IN FRONT OF
FACE stroke the electrode pint on
the
workpiece as if striking a match This
is the most correct method ter
striking the are.
WARNING!
Don’t hit the electrode on the
workpiece. which will
damge the steck electrode and
make are strike-up difficult
mmediaely aftely aftke-upr/
to maintain a distance from the
workpiece which is equivalent to the
diameter of the ele ctrode used.
Maintain this distance as constantly
