    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 Ensure to install the equipment correctly and ground the work or metal to be welded to a good electrical (earth) ground according the operation manual. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.
  • Page 5 SAFETY degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors to form phosgene, a highly toxic gas, and other irritating products.  Shielded gases used for arc welding can displace air and cause injury or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe.
  • Page 6 SAFETY Do not spill fuel when filling tank. If fuel is spilled, wipe it up and do not start engine until fumes have been eliminated. WELDING SPARKS can cause fire or explosion.  Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire.

    SAFETY Rotating parts may be dangerous.  Use only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition.
  • Page 8 SAFETY  Never coil the power cable around your body.  Make sure welding machine and power cable to be far away from the operator as far as possible according to the actual circumstance.  Connect the work cable to the workpiece as close as possible to the area being welded.

  • Page 10: Working Principle

    OVERVIEW §2.2 Working Principle The working principle of MIG F SERIES arc welding machine is shown as the following figure. Three-phase 380V work frequency AC is rectified into DC（530V）, then is converted to medium frequency AC (about 20KHz) 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.

    OPERATION If transformer is over-heat, the heat relay inside it will open and will output an instruction to circuit board, cut AC relay and the output welding current, and brighten the over-heat pilot lamp in the front panel. At this time, the machine should be relaxed for 15 minutes to cool the fan. When operating the machine again, the welding output current or the duty cycle should be reduced.
