    2 Product 2.1 General MMA series welding machine applies the most advanced inversion technology in the world. The appearance of the invert arc welding machine comes after the invert power theory and components. The principle of the technology is to transform the power frequency of 50Hz/60Hz into direct current and invert it into high frequency (33KHz) through high-power device IGBT, then perform voltage-drop and commutation with the output high-power D.C power supply via full digital Pulse Width Modulation (PWM) control technology.

  • Page 14: Installation

    3 Installation The welding equipment is equipped with power voltage compensation device. It keeps the machine work normally when power voltage fluctuating ±15% of rated voltage. When using long cable, in order to reduce voltage drop, big section cable is suggested. If the cable is too long, it will affect the performance of arcing and other system function, it is suggested to use the recommend length.

  • Page 19: Welding Problems And Resolution

    Keep good ventilation!！ The welding machines work with high welding current. Nature air flow can’t reach the requirement of heat dissipation. So the fans are installed as cooling system to ensure stable performance. Make sure the ventilation windows are not covered or blocked. The distance between the machines and things around should not be less than 0.3m.

  • Page 20: Daily Maintenance And Checking

    5 Daily maintenance and checking  Daily maintenance Remove dust regularly with dry compressed air. If the welding machine is used in surroundings with heavy smoke and polluted air, it is necessary to remove dust at least one time one month. The pressure of compressed air shall fall to required level to prevent damage to small components in the machine.
