    SAFETY 1 SAFETY 1.1 Signal Explanation  The above signals mean warning! Notice! Running parts and getting an electric shock or thermal parts will take damage for your body or others. The corresponding notices are as follows. It is quite a safe operation after taking several necessary protection measures.
  • Page 4 SAFETY semiautomatic welding gun 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 5 SAFETY 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-flaSMAWble screening and /or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
  • Page 6 SAFETY cause an explosion even though they have been “cleaned”.  Vent hollow castings or containers before heating, cutting or welding. They may explode.  Sparks and spatter are thrown from the welding arc. Wear oil free protective garments such as leather gloves, heavy shirt, cuff less trousers, high shoes and a cap over your hair.

    3.4 Power supply input connection SANARG 180AP welding machine operates on single-phase 120 - 240VAC primary power. When the power supply voltage is over voltage, there are over voltage and under voltage protection inside the welder, the alarm light will turn on, at the same time, the current output will turn off, If the power supply voltage continually goes beyond the safe work voltage range, it will shorten the welder lifespan.
