Indicates that the helmet must be worn during the step(s) that follow to protect against eye damage and burns due to flash hazard. Indicates that the possibility of toxic gas hazard exists during operation of the step(s) that follow. Indicates that the possibility of being burned by hot slag exists during operation of the step(s) that follow. - Page 5 FIRE OR EXPLOSION CAN CAUSE DEATH, INJURY AND PROPERTY DAMAGE! Fire and explosion can be caused by hot slag, sparks, or the plasma arc. Be sure there is no combustible or flam- mable material in the workplace. Any material that cannot be removed must be protected. Ventilate all flammable or explosive vapors from the workplace.
- Page 6 FUMES, GASSES AND VAPORS CAN CAUSE DISCOMFORT, ILLNESS AND DEATH! 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.

Page 11: Installation And Operation
INSTALLATION AND OPERATION SITE LOCATION CAUTION Select a clean, dry location with good ventilation and adequate working space around all components. Operation without proper air flow will inhibit proper cooling and reduce duty cycle. To prevent entry of cutting or other metal debris, the power supply must not be operated in the horizontal position. Operate the power supply in the vertical position only with the power supply control panel side up. -
