• Use adequate electrical insulation with regard to the electrode, the work piece and any (accessible)
earthed metal parts in the vicinity.
• This is normally achieved by wearing gloves, shoes, head coverings and clothing designed for this
purpose and by using insulating platforms or mats.
• Always protect your eyes using masks or helmets with a special welding filter glass.
• Use special fire-resistant protective clothing and do not allow the skin to be exposed to the
ultraviolet and infrared rays produced by the arc; other people in the vicinity of the arc should be
protected by shields of non-reflecting curtains.
• The electromagnetic fields generated by the welding process may interfere with the operation of
electrical and electronic equipment.
• Users of vital electrical or electronic devices (e.g. pace-makers, respirators etc) should consult
a doctor before stopping in the vicinity of areas where this welding machine is used.
• Users of vital electrical or electronic devices should not use the welding machine.
• This welding machine is not guaranteed to meet electromagnetic compatibility requirements in the
home.
SECTION 3 : EXTRA PRECAUTIONS
WELDING OPERATIONS:
• in environments with increased risk of electric shock;
• in confined spaces;
• in the presence of flammable or explosive materials;
MUST be evaluated in advance by an “expert supervisor” and must always be carried out in the presence of
other people trained to intervene in emergencies.
- Do not weld if the welding machine or wire feeder is supported by the operator (e.g. using belts).
- The operator must not weld in raised positions unless safety platforms are used.
VOLTAGE BETWEEN ELECTRODE HOLDERS OR TORCHES:
- Working with more than one welding machine on a single piece, or on pieces that are connected
electrically, may generate a dangerous accumulation of no-load voltage between two different electrode
holders or torches, the value of which may reach double the allowed limit.
- An expert coordinator must use measuring instruments to determine the existence of a risk and should
take suitable protection measures.
