Disclosed are a welding rod fixing apparatus including a body portion including a first surface provided in the center thereof with a first hole through which a welding rod is configured to extend, a second surface provided in the center thereof with a second hole through which the welding rod is configured to extend, the second hole located at the position corresponding to the first hole, a third surface which connects the first surface and the second surface, a space portion formed as a result of a part of an outer circumferential surface formed by the third surface being opened, the space portion being formed such that a hollow is formed from a part of the outer circumferential surface to a central part where the first hole and the second hole are connected to each other, and a fourth surface configured to form the space portion, and a coupling portion configured to be insertable into the space portion so as to press the welding rod when the welding rod extends through the first hole and the second hole, and a welding rod fixing method using the same.

The present invention relates to a welding rod fixing device and a welding rod fixing method using the same, comprising: a first surface having a first hole formed in the center thereof so that a welding rod can pass therethrough; a second surface having a second hole formed in the center thereof so that the welding rod can pass therethrough and at a position corresponding to the first hole; a third surface connecting the first surface and the second surface; a space portion formed by an outer circumferential surface formed by the third surface, the space portion being hollow from the outer circumferential surface to a center portion where the first hole and the second hole are connected; and a body portion including a fourth surface forming the space portion; and a coupling portion configured to be inserted into the space portion and to press the welding rod passing through the first hole and the second hole.

An electric welding machine comprises a first base, a handle and a second base, the first base and the second base are connected to the handle, a welding gun barrel, a wire feeder and a wire feeding reel are provided on the first base, the wire feeder is configured to feed a welding wire from the wire feeding reel to the welding gun barrel, and a control mechanism configured to control the electric welding machine to work is provided on the second base. The control mechanism controls the wire feeder to feed the welding wire of the wire feeding reel to the welding gun barrel, and welding under the welding gun barrel.

A tool includes a handle having a proximal end and a distal end, wherein the handle includes a first cylindrical cavity extending into the handle from an opening in the distal end and having a first cylindrical wall. The tool further includes a radial bearing having an inner race, an outer race, and rolling elements, wherein the outer race is secured to the first cylindrical wall of the first cylindrical cavity. Still further, the tool includes a central shaft having proximal and distal sections, wherein the proximal section is secured to the inner race, and wherein the distal section extends from the first cylindrical cavity and includes external screw threads. The tool additional includes a chuck threadably coupled to the external screw threads, wherein the chuck includes self-centering jaws for selectively gripping a tungsten electrode along an axis of rotation established by the radial bearing.
