PMA plasma gas welding machine completely replaces traditional brazing equipment. The new generation of brazing equipment without flammable gas adopts IGBT inverter control principle. When welding, the flame is very stable. The whole equipment is light and convenient, suitable for outdoor welding machine operation. Simple, a little understand the welder, no special training, this product does not require flammable and explosive gases such as acetylene, and the safety performance is greatly improved. It only takes electricity, and the advantages of using a plasma brazing machine in some underdeveloped areas (no oxygen or acetylene, gasoline, etc.) are obvious. In the welding process, the gas flux can be directly used instead of the traditional manual addition of borax to improve the wettability and fluidity of the brazing, so as to reduce the generation of pores. Improve the tensile strength of the weld, the surface is not oxidized during the welding process, and does not black. No pickling is required, which greatly improves the efficiency of the bonding.
An arc is generated between the cathode and the inner wall of the nozzle. After the gas is input, the gas is heated by the arc between the cathode and the nozzle and is completely or partially ionized, and then ejected by the nozzle to form a plasma flame, and the external flame temperature is as high as 1500 to 2800 degrees. . It can be directly used for heat treatment instead of brazing or high frequency welding.

The gas protection welding voltage is preset, the manual welding current preset adjustment function, and the welding current and the welding voltage are continuously adjustable, which can meet the needs of different welding standards and is convenient to weld. Gas Welding Machine has automatic compensation of grid fluctuations, small splash, good arc starting, deep molten pool and strong bearing capacity. It is especially suitable for welding low carbon steel and alloy steel. Its three-phase input power supply adopts IGBT technology, the wire feeding speed is stable, the whole machine is light, efficient, energy-saving and has no electromagnetic noise. At the same time, it also has a self-locking function, which reduces the labor intensity of the operator and has the function of slow wire feeding, which improves the success rate of arc striking.
