Abstract
According to an embodiment of the disclosure, a welding rod holder comprises a body, an electrical contact tip, a slider, and a biasing mechanism. The body has a lower end and an upper end. The electrical contact tip is coupled to the body and is configured to electrically contact a welding rod. The slider is configured to allow the welding rod to move with respect to the body. The biasing mechanism is configured to move the welding rod out of a lower end of the body. The hand brake is configured to selectively allow the biasing mechanism to move the welding rod out of a lower end of the body. The movement of the welding rod out of a lower end of the body is configured to allow a substantially similar distance between the body and a welding work as the welding rod is exhausted.
