MMA-120 is hand inverter welder series which is made by international most advantaged invert technical.
Inverter arc welding power supply is inverter arc welding machine which is sprung up in 1980s in international market. 50Hz/60Hz frequency is inverted to high frequency (frequency is over 100KHz) by IGBT, then steps down voltage and regulates current, inverter arc welding power supply generates powerful DC welding current through PWM technical. Due to the inverter technical of switch power is used, dimension and weight of welding machine has been reduced substantially and efficiency has been increased by 30%. Stability, reliability, lightness, energy-saving and no electromagnetic noise are the advantages of welding machine series. Inverter welding machine developed that has been given praise of revolution in the welding field by specialists.
Arc welding machine has obvious characteristics as following:
1. High quality.
2. Stable arc.
3. Molten bath is easy to control.
4. No-load voltage is higher.
5. Able to be used widely.
6. Suitable for job of high-altitude and outdoor and fitment of inside or outside.
7. Light weight.
8. Simple installing and operation.
