    • Disclosed herein is a self controlling contact tip for GMA welding (gas metal arc welding) which supports a wire (30) with constant pressure regardless of deformation of the contact tip, thus making it possible for a welding process to be steadily conducted. The self controlling contact tip includes a body part (10), a connection part (20), which is integrally coupled to the body part (10), and a wire feed hole (11) longitudinally formed through both the body part (10) and the connection part (20). The self controlling contact tip further includes a longitudinal slot (12) which is formed in the body part (10) from a front end of the body part (10) to a pre¬ determined position. The longitudinal slot (12) is enlarged in width from the front end of the body part (10) to a rear end.
    • 本文公开了一种用于GMA焊接(气体金属电弧焊接)的自控式接触尖端,其不管接触尖端的变形如何,都支撑具有恒定压力的线(30),从而可以稳定地进行焊接过程。 所述自我控制的接触尖端包括主体部分(10),与所述主体部分(10)整体联接的连接部分(20)以及通过所述主体部分(10)纵向形成的焊丝进给孔(11) 和连接部(20)。 自我控制接触尖端还包括纵向槽(12),其形成在主体部分(10)中,从主体部分(10)的前端到预定位置。 纵向狭槽(12)从主体部分(10)的前端延伸到后端。
