Inverter MMA-400D welding machine
The main features of this typeweilding machine:
1. The machine is very light and can be used in anypalce, which is suitable for decoration and maintaince industry.
2. The machine adopt single-tube IGBT invert technology, with the advantages of low power consumption, high frequency, high efficiency, good anti-jaming ability and stable arc diginition, etc.
3. The anti-electric net fluctuation of the machine, can make it adapt to wide current range.
4. This series uses constant power control, and its output current is also very stable.
5. The application of acidic, alkaline and some other type of welding, which can make the machine in full podition welding.
6 As for the application scope, this type welding machine is suitable for various types of carbon steel welding.
7 It has perfect over-voltage, under voltage, over-temperature, over current and overload automatic protect function, which made the machine is safe and reliable.
