1.0 SAFETY NORMS

1.1 GENERAL INSTRUCTIONS

Make sure this manual is carefully read and understood by the welder, and by the maintenance and technical operators

1.2 LOCATION

Welding processes of any kind can be dangerous not only to the operator but to any person situated near the equipment, if
safety and operating rules are not strictly observed.
These are the main precautionary measures to observe:
· Operators should protect their body by wearing closed, non-fl ammable protective clothing, without pockets or turned
up trousers.
· The operators should wear a non-fl ammable welding helmet designed so as to shield the neck and the face, also
on the sides. It is necessary to keep the protective lens always clean and to replace it when broken or cracked. It is
advisable to interpose a transparent glass between the lens and the welding area. Welding should be done in a closed
area that does not open into other working areas.
· The operators should never look at the voltaic arc without the correct protection to the eyes. They should always wear
safety glasses with side shields to protect from fl ying particles.
· The welding process must be performed on metal coatings thoroughly cleaned from layers of rust or paint, to avoid
production of harmful fumes. The parts degreased with a solvent must be dried before welding.
· Welding should never be done on metals or coated metals containing zinc, mercury, chromium, graphite, lead, cadmium
or beryllium unless the operator and the people standing in the same area use an air-supplied respirator.

1.3 SAFETY INSTRUCTIONS

For your safety, before connecting the power source to the line, closely follow these instructions:
· An adequate two-pole switch must be inserted before the main outlet; this switch must be equipped with time-delay
fuses;
· The single-phase connection with ground must be made with a two-pole plug compatible with the above mentioned
socket;
· The two wires of the two-pole input cable are used for the connection with the single-phase line while the yellow
– green wire for the compulsory connection to the ground in the welding area;
· When working in a confi ned space, the power source must be kept outside the welding area and the ground cable
should be fi xed to the workplace. Never work in a damp or wet area, in these conditions.
· Do not use damaged input or welding cables;
· The welding torch should never be pointed at the operator's or at other persons' body;
· The power source must never be operated without its panels; this could cause serious injury to the operator and could
damage the equipment.

1.4 FIRE PREVENTION

· Make sure that appropriate fi re prevention devices are available near to the welding area;
· All combustible material must be removed from the welding area.

1.5 ELECTROMAGNETIC COMPATIBILITY

Before installing a MIG/MAG power source, inspect the surrounding area checking the following points:
· Make sure that close to the power source there are no other power supply cables, control lines, telephone cables or
other devices;
· Make sure that telephones or TV, computers or other control systems are not in the working area;
· People with pace-maker or hearing-prosthesis should keep far from the power source.
! In particular cases special protection measures may be required.
Interference can be reduced following these suggestions:
· If there is interference in the power source line, an E.M.T. fi lter can be mounted between the power supply and the
power source;
· The output cables of the power source should be shortened, kept together and connected to ground;
· After the maintenance all the panels of the power source must be securely fastened in place.

1.6 ELECTRIC SHOCK

DANGER – ELECTRIC SHOCK CAN BE FATAL.
A qualifi ed person fi rst aid technique should always be present in the working area.
If person is unconscious and electric shock is suspected, do not touch the person if he or she is in contact with commands.
Disconnect power from the machine and then use First Aid. Dry wood, and other insulating material can be used to move
cables, if necessary, away from the person.
