IMPORTANT:

BEFORE STARTING THE EQUIPMENT,

READ THE CONTENTS OF THIS MANUAL, WHICH MUST
BE STORED IN A PLACE FAMILIAR TO ALL USERS FOR
THE ENTIRE OPERATIVE LIFE-SPAN OF THE MACHINE.
THIS EQUIPMENT MUST BE USED SOLELY FOR WELD-
ING OPERATIONS.

1  SAFETY PRECAUTIONS

WELDING AND ARC CUTTING CAN BE
HARMFUL TO YOURSELF AND OTHERS.
The user must therefore be educated

against the hazards, summarized below, deriving from weld-
ing operations. For more detailed information, order the man-
ual code 3.300.758

NOISE

This machine does not directly produce noise

exceeding 80dB. The plasma cutting/welding proce-
dure may produce noise levels beyond said limit;

users must therefore implement all precautions required by
law.

ELECTRIC AND MAGNETIC FIELDS - May be dangerous.

· Electric current following through any conduc-

tor 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) shall consult their physi-
cian before beginning any arc welding, cutting, gouging 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 cir-
cuit:

- 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. If 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.

EXPLOSIONS

· 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.

ELECTROMAGNETIC COMPATIBILITY
This machine is manufactured in compliance with the
instructions contained in the standard IEC 60974-10 (CL. A),

and must be used solely for professional purposes in an
industrial environment. There may be potential difficul-
ties in ensuring electromagnetic compatibility in non-
industrial environments.

DISPOSAL OF ELECTRICAL AND ELECTRONIC 
EQUIPMENT
Do not dispose of electrical equipment together
with normal waste!In observance of European

Directive 2002/96/EC on Waste Electrical and Electronic
Equipment and its implementation in accordance with
national law, electrical equipment that has reached the
end of its life must be collected separately and returned
to an environmentally compatible recycling facility. As the
owner of the equipment, you should get information on
approved collection systems from our local representa-
tive. By applying this European Directive you will improve
the environment and human health!

IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE
FROM QUALIFIED PERSONNEL.

1.1 WARNING LABEL

The following numbered text corresponds to the label
numbered boxes.

B.  Drive rolls can injure fingers. 
C.  Welding wire and drive parts are at welding voltage

during operation — keep hands and metal objects
away. 

1  Electric shock from welding electrode or wiring can

kill.

1.1 Wear dry insulating gloves. Do not touch electrode

with bare hand. Do not wear wet or damaged gloves. 

1.2 Protect yourself from electric shock by insulating
