1.02 Important Safety Precautions

WARNINGS

OPERATION AND MAINTENANCE OF PLASMA ARC EQUIPMENT CAN BE DAN- GEROUS AND HAZARDOUS TO YOUR HEALTH.

Plasma arc cutting produces intense electric and magnetic emissions that may interfere with the proper function of cardiac pacemakers, hearing aids, or other electronic health equipment. Per- sons who work near plasma arc cutting applica- tions should consult their medical health profes- sional and the manufacturer of the health equipment to determine whether a hazard exists.

To prevent possible injury, read, understand and follow all warnings, safety precautions and in- structions before using the equipment. Call 1-603- 298-5711 or your local distributor if you have any questions.

GASES AND FUMES

Gases and fumes produced during the plasma cutting process can be dangerous and hazardous to your health.

•Keep all fumes and gases from the breathing area. Keep your head out of the welding fume plume.

•Use an air-supplied respirator if ventilation is not adequate to remove all fumes and gases.

•The kinds of fumes and gases from the plasma arc depend on the kind of metal being used, coatings on the metal, and the different processes. You must be very careful when cutting or welding any met- als which may contain one or more of the follow- ing:

Antimony	Chromium	Mercury
Arsenic	Cobalt	Nickel
Barium	Copper	Selenium
Beryllium	Lead	Silver
Cadmium	Manganese	Vanadium

•Always read the Material Safety Data Sheets (MSDS) that should be supplied with the material you are using. These MSDSs will give you the information regarding the kind and amount of fumes and gases that may be dangerous to your health.

•For information on how to test for fumes and gases in your workplace, refer to item 1 in Subsection 1.03, Publications in this manual.

•Use special equipment, such as water or down draft cutting tables, to capture fumes and gases.

•Do not use the plasma torch in an area where com- bustible or explosive gases or materials are located.

•Phosgene, a toxic gas, is generated from the vapors of chlorinated solvents and cleansers. Remove all sources of these vapors.

ELECTRIC SHOCK

Electric Shock can injure or kill. The plasma arc process uses and produces high voltage electrical energy. This electric energy can cause severe or fatal shock to the op- erator or others in the workplace.

•Never touch any parts that are electrically “live” or “hot.”

•Wear dry gloves and clothing. Insulate yourself from the work piece or other parts of the welding cir- cuit.

•Repair or replace all worn or damaged parts.

•Extra care must be taken when the workplace is moist or damp.
