    1 SAFETY 1.1 Signal Explanation  The above signals mean warning! Notice! Running parts and electric shocks can injure or kill. It is a safe operation after taking several necessary protection measures. 1.2 Arc Welding Damage  The following signals and word explanations relay dangers present during the welding operation. Please be aware and cautious.
  • Page 5 SUMMARY semiautomatic welding torch are also electrically “hot”.  Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should be as close as possible to the area being welded. Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition.
  • Page 6 SUMMARY the arc when welding or observing open arc welding.  Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays.  Protect other nearby personnel with suitable, non-flammable screening and /or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
  • Page 7 SUMMARY SELF-PROTECTION  Keep all equipment safety guards, covers and devices in position and in good repair. Keep hands, hair, clothing and tools away from V-belts, gears, fans and all other moving parts when starting, operating or repairing equipment.  Do not put your hands near the engine fan. Do not attempt to override the governor or idler by pushing on the throttle control rods while the engine is running.

    SUMMARY area.  Connect the work cable to the work as close to the welding area as practical. Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding current passing through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains or cables until they fail.
