Instruction Manual

Read this instruction manual carefully before using the welding machine.

MIG/MAG continuous wire arc-welding machines, referred to in this manual as “welding

machines”, are designed for industrial and professional use.

Make sure that the welding machine is installed and repaired only by qualied 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

processs 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: IEC or CLC/TS 62081.

Safety warnings

 Make sure that the power socket to which the welding machine is connected is protected

by suitable safety devices (fuses or automatic switch) and that it is grounded.

 Make sure that the plug and power cable are in good condition.

 Before plugging into the power socket, make sure that the welding machine is switched off.

 Switch the welding machine off and pull the plug out of the power socket as soon as you

have nished working.

 Switch the welding 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

welding machine).

 Do not touch any electried parts with bare skin or wet clothing. Insulate yourself from the

electrode, the piece to be welded and any grounded accessible metal parts. Use gloves,

footwear and clothing designed for this purpose and dry, non-ammable insulating mats.

 Use the welding machine in a dry, ventilated space. Do not expose the welding machine

to rain or direct sunshine.

 Use the welding machine only if all panels and guards are in place and mounted correctly.

 Do not use the welding machine if it has been dropped or struck, as it may not be safe.

Have it checked by a qualied person or an expert.

 Eliminate any welding fumes through appropriate natural ventilation or using a smoke

exhauster. A systematic approach must be used to assess the limits of exposure to welding

fumes, depending on their composition, concentration and the length of exposure.

 Do not weld materials that have been cleaned with chloride solvents or that have been

near such substances.

 Use a welding mask with adiactinic glass suited for welding. Replace the mask if damaged;

it may let in radiation.

 Wear reproof 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 re to

them. Use protective screens to protect people nearby.

 Do not allow bare skin to come into contact with hot metal parts, such as the torch, electrode

holder grippers, electrode stubs, or freshly welded pieces.

 Metal-working gives off sparks and splinters. Wear safety goggles with protective side

eye guards.

 Welding sparks can trigger res.

 Do not weld or cut anywhere near inammable materials, gasses or vapours.

 Do not weld or cut containers, cylinders, tanks or piping unless a qualied technician or

expert has checked that it is possible to do so, or has made the appropriate preparations.

 Never direct the torch towards yourself, others or metal parts; the continuous wire could

make holes or cause short circuits.

 Switch off the welding machine and pull the plug out of the power socket before carrying

out any manual operations on the moving parts of the wire feeder.

EMF Electromagnetic Fields

Welding current creates electromagnetic elds (EMF) near the welding circuits and

the welder. Electromagnetic elds may interfere with medical prostheses such as

pacemakers.

Suitable and sufcient 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 specic 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 elds at home is not ensured.

Follow these strategies to minimise exposure to electromagnetic elds (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 9 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 difcult to ensure compliance to electromagnetic compatibility as the result of

conducted or radiated disturbances.

Welding in conditions of risk

 If welding needs to be done in conditions of risk (electric discharges, suffocation, the

presence of inammable 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 5.10;

A.7; A.9 of the IEC or CLC/TS 62081 technical specication.

 If you are required to work in a position raised above ground level, always use a safety

platform.

 If more than one welding 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 5.9 of the IEC or CLC/TS 62081 technical specication if required.

Additional warnings

 Do not use the welding machine for purposes other than those described, for example to

thaw frozen water pipes.

 Place the welding machine on a at 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 welding sparks.

 Do not lift the welding machine. No lifting devices are tted on the machine.

 Do not use cables with damaged insulation or loose connections.

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 at

(constant voltage).
