• Abrasion in the insulation or contact parts with the electrical current may cause risk of electric shock
and lower the quality of the cut/weld;
• The ground clamp must be directly fastened to the part to be welded. Ensure that there is direct
contact between the clamp and the part to be welded. Therefore, avoid painted or insulated surfaces;
• Stay in a stable position during the cutting/welding process;
• Do not use the equipment in wet or slippery fl oor/ground;
• Never wind the cables of the cutting/welding equipment around its housing;
• Never stay between the cable of the torch and the ground cable. If the torch is on your right, the
ground cable must also be on your right;
• Never use the equipment without the cabinet cover;
• Provide a fi re extinguisher for the work place. For further information about the fi re extinguisher to be
used, contact your local Fire Brigade;
• Avoid direct contact with the plasma arc cutting;
• The voltage of the open circuit between the torch and the ground cable may be dangerous; therefore,
handle the equipment with care. There is risk of electric shock;
• Do not put or use the equipment in humid or wet environments or exposed to rain;
• Never soak the torch in water to cool it and keep it in a place free of humidity;
• Plasma arc cutting produces sparks, splashes and smokes; therefore, remove all fl ammable substan-
ces or materials form the work place and surroundings;
• Connect the ground clamp as close as possible to the part to be cutted/welded, so that the cutting/
welding current can go through the shortest way from the torch and the ground cable.
• Never connect the ground clamp to the cover of the cutting equipment or grounded parts away from the
work piece.
About the operator’s and other people’s safety:
• If any anomalies or unexpected behavior of the cutting/welding equipment occur during operation, imme-
diately disconnect the equipment from power supply and contact an expert in electricity to help you;
• In case of accident, disconnect the equipment immediately from the power supply and look for a doctor. Do
not try to restart the equipment before sending it to an expert in electricity for an analysis;
• It is not recommended the use of this equipment by people with dent pacemaker.
When ON, this equipment may cause interference in the operation of the pacemaker. For further infor-
mation, refer to a doctor;
• Protect the face with a proper welding mask (protection mask), which is in accordance with the appli-
cable local safety law. The welding mask must be used all the time from the opening of the arc to the
end of the job. It protects the face against the radiations emitted by the arc, allowing clear visualization
of the work piece. Do not look at the electric arc without this protection! The ultra-violet radiation is
invisible; however, it causes Burns on the skin and eyes similar to those caused by the sun;
• If the work of welding requires, for instance, working a piece above the head, a helmet is also ne-
cessary;
• Wear gloves, safety shoes and protection clothes free of humidity, oil or grease during the cutting/
weldingjob. The clothing must protect the body from ultra-violet radiation of the electric arc;
• Plasma arc cutting also produces sparks and splashes of the melted material. Therefore, check the
applicable safety Law for proper clothing, shoes and protection gloves for welding jobs. Do not wear
synthetic clothes. The use of protective equipment is imperative to ensure the operator’s safety;
• Due to sparks and splashes of incandescent material, the work piece and other objects nearby remain hot
for some time. Therefore, do not handle any objects near the cutting/welding place without proper protective
