Electrode clamping device

An electrode clamping device (3) for mechanically clamping a non-consumable rod-shaped welding electrode (2) in a welding torch (1), the electrode clamping device (3) having a chuck (3A) mounted into the welding torch (1) from the rear into a chuck housing (3B) of the electrode clamping device (3) which surrounds the chuck (3A), wherein the chuck (3A) is arranged so as to be movable relative to a chuck housing (3B) surrounding the chuck along a longitudinal axis of the rod-shaped welding electrode (2) in order to mechanically clamp and release the rod-shaped welding electrode (2). 一种用于在焊炬(1)中机械地夹紧非消耗的杆状焊接电极(2)的电极夹紧装置(3)，其中电极夹紧装置(3)具有从后部进入电极夹紧装置(3)的夹头壳体(3B)中而安装到焊炬(1)中的夹头(3A)，该夹头壳体环绕夹头(3A)，其中夹头(3A)被设置为能相对于环绕夹头的夹头壳体(3B)沿着杆状焊接电极(2)的纵向轴线移动以便机械地夹紧和释放杆状焊接电极(2)。
