USE AS WELDER
M

REV.0-10/99
This symbol (Norm EN 60974-1 security
standards for arc welders ) signifies that the
welder can be used in areas with increased
risk of electrical shock.
Check at the beginning of any work the electric
parameters and/or the control placed on the front.
Make sure that the ground connection (12) is efficent
(keep to installation local rules and/or to national
laws), in order to integrate or ensure the working
of varius electric protection devices referring to the
several distribution system TT/TN/IT, operation un-
necessary for machine with isometer.
Fully insert the welding cable plugs into the corre-
sponding sockets (“only gauging”, 9
+
/10
-
) turnning
them clockwise to lock them in position.
+
Make sure that the ground clamp ,whose cable
must be connected to the + or - terminal, de-
pending on the type of electrode, makes a
good connection and is near to the welding
position.
Pay attention to the two polarities of the welding
circuit, which must not come in electric contact
between themselves.
When using the welder for air arc gouging connect
the ground lead to the - socket and the gouging
lead to the socket marked "only gouging
"
(if
present).
MACHINES WITH E.V. PROTECTION
Accelerate the engine at max. with the acce-
lerator lever (16).See page M 39.
MACHINE WITH E.P.2 PROTECTION (B2)
Accelerate the engine at max. with
the accelerator lever (16) (when
assebled).
See page M 39
MACHINE WITH E.P.1 PRO-
ONLY GOUGING
TECTION (D1)

WELDING CURRENT REGULATOR
Position welding current adjusting knob (T) in cor-
respondance of the chasen current value, so as to
obtain the necessary amperage, taking into acount
the diameter and the type of the electrode.

ATTENTION
The sockets, after the machine is started (see
pages M21-26), also with no cables, are anyway
under voltage.
ATTENTION
The areas, access of which is forbiden to unqua-
lified personel, are:
- the control switchboard (front) - the exhaust of
the endothermic engine - the welding process.
ATTENTION
To reduce the risk of electromagnetic interferen-
ces, use the minimum lenght of welding cables
and keep them near and down (ex. on the floor).
The welding operations must take place far from
any sensitive electronic device.Make sure that
the unit is earthed. (see M20 and/or M25). In
case the interference should last, adapt further
disposition,such as: move the unit, use screened
cables, line filters, screen the entire work area.
In case the above mentioned operations are non
sufficient, please contact our Thechnical Assistan-
ce Service.
CAUTION
With a
welding cable length up to 20 m is
suggested a section of 35 mm²; wìth longer
cables a bigger section is required.
