1 SAFETY PRECAUTIONS
WELD NG AND ARC CUTT NG CAN BE HARMFUL TO
YOURSELF AND OTHERS. The user must therefore be edu-
cated against the hazards, summarized below, deriving from
welding operations. For more detailed information, order the
manual code 3.300.758
NO SE This machine does not directly produce noise
exceeding 80dB. The plasma cutting/welding pro-
cedure may produce noise levels beyond said
limit; users must therefore implement all precautions
required by law.
ELECTR C AND MAGNET C F ELDS - May be dangerous.
· Electric current following through any con-
ductor causes localized Electric and Magnetic
Fields (EMF). Welding/cutting current creates
EMF fields around cables and power sources.
· The magnetic fields created by high currents
may affect the operation of pacemakers. Wearers of vital
electronic equipment (pacemakers) should consult their
physician before beginning any arc welding, cutting, goug-
ing or spot welding operations.
· Exposure to EMF fields in welding/cutting may have other
health effects which are now not known.
· All operators should use the followingprocedures in order
to minimize exposure to EMF fields from the welding/cutting
circuit:
- Route the electrode and work cables together - Secure
them with tape when possible.
- Never coil the electrode/torch lead around your body.
- Do not place your body between the electrode/torch
lead and work cables. f the electrode/torch lead cable
is on your right side, the work cable should also be on
your right side.
- Connect the work cable to the workpiece as close as
possible to the area being welded/cut.
- Do not work next to welding/cutting power source.
EXPLOS ONS
· Do not weld in the vicinity of containers under pres-
sure, or in the presence of explosive dust, gases or
fumes. · All cylinders and pressure regulators used in
welding operations should be handled with care.

5 AINTENANCE
Any maintenance operation must be carried out by qua-
lified personnel in compliance with standard CEI 26-29
(IEC 60974-4).
5.1 GENERATOR AINTENANCE
n the case of maintenance inside the machine, make
sure that the switch Pis in position "O" and that the
power cord is disconnected from the mains.
t is also necessary to periodically clean the interior of the
machine from the accumulated metal dust, using com-
pressed air.
5.2 PRECAUTIONS AFTER REPAIRS.
After making repairs, take care to organize the wiring so that
there is secure insulation between the primary and secon-
dary sides of the machine. Do not allow the wires to come
into contact with moving parts or those that heat up during
operation. Reassemble all clamps as they were on the origi-
nal machine, to prevent a connection from occurring
between the primary and secondary circuits should a wire
accidentally break or be disconnected.
Also mount the screws with geared washers as on the ori-
ginal machine.
