Abstract
The utility model relates to a secondary compression type plasma welding gun. The secondary compression type plasma welding gun comprises a gun cap, wherein the gun cap is connected with a gun body through a fine adjustment centering pipe, and a gun handle is connected to the gun body. The secondary compression type plasma welding gun is characterized in that a circulating water pipe inlet-outlet connector and a protective gas inlet connector are arranged in the gun handle, and an air cylinder is arranged above the gun body. Meanwhile, a tungsten electrode is installed in the middle of the gun body, and compression nozzles are distributed below the gun body and comprise a primary water cooling nozzle. A secondary water cooling nozzle is arranged outside the primary water cooling nozzle, and a plasma gas channel is formed between the primary water cooling nozzle and the secondary water cooling nozzle. Therefore, secondary compression can be carried out on electric arcs through the two compression nozzles formed by the primary water cooling nozzle and the secondary water cooling nozzle, and the electric arcs can be higher in concentration degree and better in stiffness. The energy utilization rate is improved, economic benefits are increased, and the wielding thickness of plasma welding is increased.
