Provided is a device for preventing tangling of welding wire. The device for preventing tangling of welding wire comprises a wire pressing member mounted on an upper end surface of a welding wire coiling member stacked in a pail pack; a wire guide member positioned in an inner side of the wire pressing member to guide a welding wire W that is being drawn from the welding wire coiling member; and at least two connection members connecting the wire pressing member and the wire guide member so that the wire pressing member and the wire guide member can move independently in relation to each other. By means of reducing the drawing resistance force when drawing the welding wire, the device is capable of drawing the welding wire from a pail pack easily.
