Abstract
Abstract There is disclosed a welding rod holder arrangement including a welding rod receiving member of electrically conductive material and having a welding rod receiving and contacting portion that is externally tapered so as to frictionally receive an electrically conductive loop on the end of a welding electrode or wire. The welding rod receiving member is slotted for air-cooling purposes and a slotted casing means of insulating material surrounds a substantial portion of said welding-rod-receiving member while leaving exposed a sufficient length of said externally tapered offset portion as to provide a large surface area for electrical contact with the electrically conductive loop. There is also disclosed a welding electrode or welding wire having an integrally formed electrically conducting eye or loop at one end thereof that ensures a substantial area of contact with the externally tapered portion of the welding-rod-receiving member.
