The present invention relates to an automatic welding machine. As driving speed of a driving unit driving around each corner of a welding object including an air conditioning box is more rapid than the driving speed of the driving unit driving on the rest periphery except for the periphery of each corner of the welding object, a welding layer having the even thickness is formed on the welding object including the air conditioning box. Furthermore, the quality of the welding object including the air conditioning box becomes more excellent. |
