SAFETY RULES AND GENERAL WARNINGS

INTRODUCTION
Your plasma cutting unit is fitted with sophisticated safeguards which block functio-
ning and therefore the cutting operations until all the safety conditions are present.
The plasma cutting technique requires dangerously high voltage for pilot arc starting
and during cutting, therefore the following safety rules must be observed with great
care.
ELECTRICITY
1 Make sure that the unit is earthed and that the supply line has an adequate earth
connection.
2 Make sure that the work bench has a satisfactory earth connection.
3 Avoid contact between the metal bars being cut and bare skin or damp clothes.
4 Do not lean on the piece being cut or hold it in your hands.
5 Do not carry out cutting operations in damp environments or on wet surfaces.
6 Do not use the unit if the torch or cables appear damaged.
7 Always turn the unit off before replacing the electrode, the nozzle or the spreader
tip of the torch.
8 Always switch the unit off and remove the power cable from the mains socket be-
fore carrying out any maintenance inside the unit.
Repairs, maintenance and operation of the unit should be carried out by trained
personnel who are aware of the risks caused by the high voltage needed to ope-
rate the plasma cutting unit. The operator should work in compliance with current
If during the cutting operation a slight electric shock is felt, stop work immediately and do
not use the unit until the fault has been discovered and resolved.
EYE AND BODY PROTECTION
One of the hazards during the cutting process is the emission of electromagnetic waves due to the elec-
tric arc. The length of these waves ranges from infrared to ultraviolet. If these rays hit the eyes, they can
cause various complaints such as conjunctivitis, burns to the retina, deterioration of sight, etc. Moreover
a high concentration of ultraviolet rays can burn the skin. It is, therefore, extremely important that the
operator uses adequate safety equipment and clothing, such as:
1 Split or leather gloves
2 Split or leather aprons
3 Shin-guards
4 Safety shoes
5 Safety mask (or even better helmet) large enough to cover the whole of the face, equipped with safety
lenses able to filter all the radiation and reduce the intensity of the light absorbed by the eye.
