SAFETY RULES AND GENERAL WARNINGS
INTRODUCTION
Your plasma cutting unit is fitted with sophisticated safeguards which block
functioning 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 before 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 operate the plasma cutting
unit. The operator should work in compliance with current standards and abide by all safety
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
electric 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:
