    200 AC/DC 1. SAFETY 1.1 Signal Explanation  Welding may damage your body or others, so please take protection measure in operation.  Only ones who are trained professionally can install, debug, operate, maintain and repair the equipment.  Do not maintain and repair the machine when the machine is connected with power.
  • Page 4 200 AC/DC FUMES AND GASES CAN BE DANGEROUS  Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone.
  • Page 5 200 AC/DC ELECTRIC SHOCK CAN KILL.  Never touch electrical parts.  Wear dry, hole-free gloves and clothes to insulate yourself.  Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.

  • Page 6: The Knowledge Of Electric And Magnetic Fields

    200 AC/DC  Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situation.  When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard.
