| Abstract: |
| In this paper,the working principle,the block diagram and the operating chara-cteristics of a transister power source for the new short cirouting CO2 shielded arc welding are introduced.When this transistor power source is used for the short circui-ting CO2 welding,the metal transfer is controlled and regular,thus featuring uniform particles,low spattering,very good appearance of weld and high productivity. |
