The welding machine adopts the most advanced investor technology. The development of welding equipment with reverse gas protection benefits from the development of the theory and components of the UPS power supply. The armed welding energy source to the inverter uses a high-power IGBT component for transferring 50/60 Hz, then reduces the voltage and switch, and produces a high voltage of power through PWM technology.

Due to the great power of the main weight and volume transformers, efficiency increased by 30%. The appearance of the solder welding equipment is considered a revolution for the welding industry. When the stick and the work piece are shortened, react faster. This means that it is easier to design in a welding machine with different dynamic characteristics and it is even possible to adjust it according to the specialty to make the arc softer or harder.

The MMA welding machine has the following characteristics: Efficiency, energy saving, compact and stable arc, good welding effect, high vacuum voltage, good force compensation and multipurpose. It can weld stainless steel, alloy steel, carbon steel, copper and other colored metals. It can be applied to electrodes of different specifications and materials, including acidity, alkalinity and fibers. It can be applied at high altitude, outdoors and indoors and outdoors. In comparison with the same domestic and foreign products, it is compact, light, easy to install and use.
