11 SAFETY INSTRUCTIONS Arc Welding Hazards The safety information given below is only a summary of the more complete safety information found in the Safety Standards listed in Section 1-5. Read and follow all Safety Standards. Only qualified persons should install, operate, maintain, and repair this unit. During operation, keep everybody, especially children, away. - Page 17 FUMES AND GASES can be hazardous. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. Keep your head out of the fumes. Do not breathe the fumes. If inside, ventilate the area and/or use exhaust at the arc to remove welding fumes and gases. If ventilation is poor, use an approved air-supplied respirator.
- Page 18 HOT PARTS can cause severe burns. Do not touch hot parts bare handed. Allow cooling period before working on gun or torch. MAGNETIC FIELDS can affect pacemakers. Pacemaker wearers keep away. Wearers should consult their doctor before going near arc welding, gouging, or spot welding operations.
- Page 19 MOVING PARTS can cause injury. Keep away from moving parts such as fans. Keep all doors, panels, covers, and guards closed and securely in place. H.F. RADIATION can cause interference. High-frequency (H.F.) can interfere with radio navigation, safety services, computers, and communications equipment.
