Micro Plasma Welding Machine:
In Micro Plasma Welding, a second nozzle is used in addition to shielding gas nozzle. Through this second nozzle, plasma flows, surrounding and constricting the arc, which leads to a high power density and stability. The surrounding gas protects the melt bath of oxidation.
The advantages of plasma arc welding are: - higher welding speed and less distortion as well as a higher insensitivity regarding changes in distance. Due to the stabilizing effect of the plasma it is possible to work even with low currents. This makes micro plasma welding suitable for joining very thin metal sheets.
