Drag-gun™ lt SECTION 1: GENERAL INFORMATION 1.01 Notes, Cautions and Warnings GASES AND FUMES Gases and fumes produced during the plasma cutting process can be dangerous and hazardous to your health. Throughout this manual, notes, cautions, and warnings are used to highlight important information. These highlights are categorized as follows: • Keep all fumes and gases from the breathing area. Keep your head out of the welding fume plume.
Drag-Gun™ lt 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 operator or others in the workplace. NOISE Noise can cause permanent hearing loss. Plasma arc processes can cause noise levels to exceed safe limits. You must protect your ears from loud noise to prevent permanent loss of hearing. • Never touch any parts that are electrically “live” or “hot.
