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.
The welding sockets, after the machine is started,
also with no cables, are anyway under voltage.
ATTENTION
!
To reduce the risk of electromagnetic interferences,
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 Technical Assistance
Service.
ATTENTION
!
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
unnecessary for machine with isometer.
Fully insert the welding cable plugs into the corre-
sponding sockets (“only gauging”, 9
+
/10
-
) turning
them clockwise to lock them in position.
Make sure that the ground clamp ,whose ca-
ble must be connected to the + or - terminal,
depending 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).

See page M 38
With a
welding cable length up to 20 m is
suggested a section of 35 mm²; wìth longer cables
a bigger section is required.

WELDING CURRENT REGULATION KNOB
Position knob (T) in correspondance of the chosen
current value, so as to obtain the
necessary amperage, taking into
acount the diameter and the type
of the electrode.
