    • An electric arc torch includes a torch base, and a cooling conduit having a conduit wall forming a central axial bore and having a plurality of longitudinal cooling channels spaced circumferentially around the bore. The cooling channels extend through the conduit wall from a first end portion to a second end portion of the conduit. The cooling channels include both a plurality of cooling liquid distribution channels and a plurality of cooling liquid return channels alternately arranged within the conduit wall. The conduit includes a circumferential cooling liquid manifold in fluid communication with each of the cooling liquid distribution channels, a circumferential return manifold in fluid communication with each of the cooling liquid return channels, and a circumferential recirculation manifold in fluid communication with each of the cooling liquid distribution and return channels such that the cooling liquid distribution and return channels are in fluid communication through the circumferential recirculation manifold.
    • 电弧焊炬包括炬基座和冷却导管,其具有形成中心轴向孔的导管壁,并且具有围绕所述孔周向间隔开的多个纵向冷却通道。 冷却通道从导管壁延伸通过导管的第一端部到第二端部。 冷却通道包括多个冷却液体分配通道和交替布置在导管壁内的多个冷却液体返回通道。 导管包括与每个冷却液体分配通道流体连通的圆周冷却液歧管,与每个冷却液返回通道流体连通的周向回流歧管以及与每个冷却液体流体连通的周向再循环歧管 分配和返回通道,使得冷却液体分配和返回通道通过圆周再循环歧管流体连通。

    • The invention relates to a plug part (21) for detachably connecting a torch neck (19) of a gas-cooled welding torch (7) to a socket part (34) disposed on a hose package (20), comprising a cylindrical pipe element (22) with a flange (25) and with an axially extending channel (23) for a welding wire (9) and for a protective gas (5) and comprising a union nut (24) which is rotatably disposed on the pipe element (22) and which comprises an inner thread for connection to a corresponding outer thread on the socket part (34). The invention also relates to such a socket part (34). The aim of the invention is to produce an optimal connection between the torch neck (19) and the hose package (20). This is achieved in that a bevel (32) is disposed on the flange (25) of the pipe element (22) of the plug part (21), and the end piece (35) of the socket part (34) has at least one axial slot (39).
    • 本发明涉及一种用于将气冷式焊炬(7)的炬颈(19)可拆卸地连接到设置在软管封装(20)上的插座部分(34)的插头部分(21),包括一个圆柱形管件 (22),其具有法兰(25)和用于焊丝(9)和用于保护气体(5)的轴向延伸的通道(23),并且包括可旋转地设置在管道元件上的联管螺母(24) 22),并且其包括用于连接到所述插座部分(34)上的相应外螺纹的内螺纹。 本发明还涉及这种插座部件(34)。 本发明的目的是在割炬颈(19)和软管封装(20)之间产生最佳的连接。 这是通过在插头部分(21)的管元件(22)的凸缘(25)上设置斜面(32),并且插座部分(34)的端部件(35)至少具有 一个轴向槽(39)。
