Abstract:
1. A closed-jaw welding electrode holder that offers a tighter grip on welding electrodes, offers improved durability and extended life, allows easier replacement of used welding electrodes, and allows easier bending of welding electrodes comprising: a head with a closed end that is made of a metal with high thermal conductivity; at least one insert within said head that is harder than the material of said head and creates a double-V-shaped hole within said head; a jaw that may move back and forth within a slot to bisect said double-V-shaped hole and allow tight gripping of said welding electrode; a body that attaches to said head; a spring fastened between said jaw and said body that governs the relative movement of said jaw with respect to said body; a sleeve that tightly encloses said body of said welding electrode holder, contains an opening to accommodate a welding lead, and improves a user's grip on said welding electrode holder; a lug that attaches said welding lead to said body; a hole in said body that can accommodate a fastener; and, a fastener that fits into said hole in said body and attaches said lug, said welding lead and said body together.
