    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 5 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 6 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. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

    2. SUMMARY This operation manual is suitable for the models of ARC 315 MV (PFC) • 2.1. Brief Introduction ARC 315 MV (PFC) welders are general MMA arc welder which adopts the latest pulse width modulation (PWM) technology and the insulated gate bipolar transistor (IGBT) power module. It can change work frequency to medium frequency so as to replace the traditional hulking work frequency transformer with the cabinet medium frequency transformer.

  • Page 8: Working Principle

    • 2.2. Working Principle The working principle of ARC 315MV (PFC)welder is shown as the following figure. Single phase 110V－ 460V±10% work frequency (50/60 Hz) AC is rectified into DC, three phase 220V－460V±10% work frequency (50/60 Hz) AC is rectified into DC, then by PFC circuit, DC(about 750V) is converted to medium...

  • Page 11: Duty Cycle & Over Heat

    • 3.2. Duty cycle & Over heat The letter “X” stands for duty cycle, which is defined as the proportion of the time that a machine can work continuously within a certain time (10 minutes). The rated duty cycle means the proportion of the time that a machine can work continuously within 10 minutes when it outputs the rated welding current.
