SECTION 1 – SAFETY PRECAUTIONS – READ BEFORE USING Protect yourself and others from injury—read, follow, and save these important safety precautions and operating instructions. 1-1. Symbol Usage DANGER! – Indicates a hazardous situation which, if not avoided, will result in death or serious injury. The possible hazards are shown in the adjoining symbols or explained in the text.
HOT PARTS can burn. WELDING can cause fire or explosion. � Do not touch hot parts bare handed. � Allow cooling period before working on equipment. Welding on closed containers, such as tanks, drums, or pipes, can cause them to blow up. �...
� Never weld on a pressurized cylinder—explosion will result. CYLINDERS can explode if � Use only correct compressed gas cylinders, regulators, hoses, damaged. and fittings designed for the specific application; maintain them Compressed gas cylinders contain gas under high and associated parts in good condition. pressure.
� To reduce possible interference, keep weld cables as short as ARC WELDING can cause possible, close together, and down low, such as on the floor. interference. � Locate welding operation 100 meters from any sensitive electronic equipment. � Electromagnetic energy can interfere with sensitive electronic equipment such as microprocessors, �...
