    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  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 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.
  • Page 6  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.

  • Page 7: Working Principle

    §2.2 Working Principle The working principle of MM SERIES arc welding machine is shown as the following figure. Single-phase 110V/220V work frequency AC is rectified into DC, then is converted to medium frequency AC by inverter device (IGBT), after reducing voltage by medium transformer (the main transformer) and rectifying by medium frequency rectifier (fast recovery diodes), and is outputted by inductance filtering.
