Instruction Manual
Read this instruction manual carefully before using the welding machine.
The MMA, TIG, MIG/MAG arc welding systems, Plasma cutting systems referred to
herein as "machine" are for industrial and professional use.
Make sure that the machine is installed and repaired only by qualified persons or experts,
in compliance with the law and with the accident prevention regulations.
Make sure that the operator is trained in the use and risks connected to the arc-welding
process / plasma cutting process and in the necessary measures of protection and
emergency procedures.
Detailed information can be found in the "Installation and use of arc-welding equipment"
brochure: EN60974-9.
Safety warnings
„ Make sure that the plug and power cable are in good condition.
„ Switch the machine off and pull the plug out of the power socket before connecting the
welding cables, installing the continuous wire, replacing any parts in the torch or wire
feeder, carrying out maintenance operations, or moving it (use the carrying handle on
the machine).
„ Before plugging into the power socket, make sure that the machine is switched off.
„ Switch the machine off and pull the plug out of the power socket as soon as you have
finished working.
„ Do not touch any electrified parts with bare skin or wet clothing. Insulate yourself from
the electrode, the piece to be cut and any grounded accessible metal parts. Use gloves,
footwear and clothing designed for this purpose and dry, non-flammable insulating mats.
„ Use the machine in a dry, ventilated space. Do not expose the welding machine to rain
or direct sunshine.
„ Use the machine only if all panels and guards are in place and mounted correctly.
„ Eliminate any welding (cutting) fumes through appropriate natural ventilation or using a
smoke exhauster. A systematic approach must be used to assess the limits of exposure
to welding (cutting) fumes, depending on their composition, concentration and the length
of exposure.
„ Do not weld (cut) materials that have been cleaned with chloride solvents or that have
been near such substances.
„ Use a welding mask with inactinic glass suitable for welding (cutting) operations. Replace
the mask if damaged; it may let in radiation. (EN 169; EN 379; EN 175)
„ Wear fireproof gloves, footwear and clothing to protect the skin from the rays produced
by the welding arc and from sparks. Do not wear greasy garments as a spark could set
fire to them. Use protective screens to protect people nearby. (EN11611; EN 12477)
„ Do not allow bare skin to come into contact with hot metal parts, such as the torch,
electrode holder grippers, electrode stubs, or freshly cut pieces.
„ Metal-working gives off sparks and splinters. Wear safety goggles with protective side
eye guards.
„ Noise: If the daily personal noise exposure (LEPd) is equal to or higher than 85 dB(A)
because of particularly intensive welding operations, suitable personal protective means
must be used Fig.4.
„ Welding (cutting) sparks can trigger fires.
„ Do not weld or cut anywhere near inflammable materials, gasses or vapours.
„ Do not weld or cut containers, cylinders, tanks or piping unless a qualified technician or
expert has checked that it is possible to do so, or has made the appropriate preparations.
„ Remove the electrode from
the electrode holder gripper when you have completed
the welding operations. Make sure that no part of the electrode holder gripper electric
circuit touches the ground or earth circuits: accidental contact could cause overheating
or trigger a fire.
EMF Electromagnetic Fields
Welding current creates electromagnetic fields (EMF) near the welding circuits and
the welder. Electromagnetic fields may interfere with medical prostheses such as
pacemakers.
Suitable and sufficient measures should be implemented to protect those operators
having such aids. For instance, they should not be allowed to enter that area where
welding equipment is used. Any operator having such aids should consult their doctor
before coming close to an area where welding equipment is used.
This device meets the specific requirements of the product technical standard and is
intended for professional use in an industrial environment only. Compliance to expected
limits for human exposure to electromagnetic fields at home is not ensured.
Follow these strategies to minimise exposure to electromagnetic fields (EMF):
„ Do not place your body between the welding cables. Both welding cables should be on
the same side of your body.
„ Twist both welding cables together and secure them with tape when possible.
„ Do not wrap the welding cables around your body.
„ Connect the earth cable to the workpiece as close as possible to the area to be welded.
„ Do not work with the welder hanging from your body.
„ Keep your head and trunk as far as possible from the welding circuit. Do not work close to
the welder, or seated or leaning on it. Minimum distance: Fig 8 Da = cm 50; Db = cm.20

Class A equipment
This equipment has been designed to be used in professional and industrial environments.
If this equipment is used in domestic environments and those directly connected to a
low voltage power supply network which supplies buildings used for domestic purposes,
it may be difficult to ensure compliance to electromagnetic compatibility as the result of
conducted or radiated disturbances.
Welding (cutting) in conditions of risk
„ IIf you are required to work in conditions of risk (electric discharges, suffocation, the
presence of inflammable or explosive materials), make sure that an authorised expert
evaluates the conditions beforehand. Make sure that trained people are present who
can intervene in the event of an emergency. Use the protective equipment described in
7.10; A.8; A.10 of the EN 60974-9. technical specification.
„ If you are required to work in a position raised above ground level, always use a safety
platform.
„ If more than one machine has to be used on the same piece, or in any case on pieces
connected electrically, the sum of the no-load voltages on the electrode holders or on
the torches may exceed the safety levels. Make sure that an authorised expert evaluates
the conditions beforehand to see if such risk exists and adopt the protective measures
described in 7.9 of the EN 60974-9 technical specification if required.
Additional warnings
„ Do not use the machine for purposes other than those described, for example to thaw
frozen water pipes.
„ Place the machine on a flat stable surface, and make sure that it cannot move. It must
be positioned in such a way as to allow it to be controlled during use but without the risk
of being covered with sparks.
„ Do not lift the machine. No lifting devices are fitted on the machine.
„ Do not use cables with damaged insulation or loose connections.
„ Only use an extension lead when absolutely necessary and providing it has an equal or
larger section to the power cable and is fitted with a grounding conductor.
„ Do not block the machine air intakes. Do not store the machine in containers or on
shelving that does not guarantee suitable ventilation.
„ Do not use the machine in any environment in the presence of gas, vapours, conductive
powders (e.g. iron shavings), brackish air, caustic fumes or other agents that could
damage the metal parts and electrical insulation.
Environmental conditions (EN 60974-1)
„ Use the welding machine with the following environmental conditions only:
„ Ambient temperature between -10°C and 40°C;
„ Relative humidity of the air ≤ 50% at 40°C
„ Relative humidity of the air ≤ 90% at 20°C
„ The surrounding air must be free of dust, acid, gas or corrosive substances, etc.
Storage
„ Ambient temperature between -20°C and 55°C.
„ Always use adequate measures to protect the machine from humidity, dirt and corrosion.
Description of the welding machine
The welding machine is a current generator for continuous wire welding, commonly
known as MIG / MAG, suited to welding carbon or light alloy steels, stainless steel and
aluminium using protective gas.
The electrical characteristic of the transformer is flat (constant voltage).
The welding machine is a current transformer for manual arc welding using MMA coated
electrodes and TIG with a torch that strikes the arc on contact.
The delivered current is direct.
The electrical characteristic of the transformer is of the falling type.
The welding machine is built using electronic INVERTER technology.
This manual refers to a range of welding machines that differ in some of their
characteristics. Identify your model in Fig. 1.
