The plasma arc welding machine is a welding method using a plasma arc as a heat source. The gas is dissociated by the arc heating and is compressed at high speed through the water-cooled nozzle, increasing the energy density and the degree of dissociation to form a plasma arc.The stability, heat generation, and temperature of china plasma arc welding machine are higher than those of ordinary arcs, and therefore have greater penetration and welding speeds. The gas forming the plasma arc and its surrounding protective gas generally use argon. According to the material properties of various workpieces, there are also mixed gases such as argon and hydrogen.
