A welding electrode apparatus has a base member and a locking ring for clamping a consumable electrode tip to the electrode base. The base and the tip are predominantly made of copper, or a copper alloy. The base member has a first end that is threaded to fit a welding head that supplies electric current; and an electrically conductive second end to which the electrode tip is mounted. The second portion has an externally facing, axially extending cylindrical wall. A circumferential groove is formed in the wall. The locking ring has a quick-disconnect feature in the form of an array of spring-loaded detents that deflect to release the cylindrical wall of the first member, and that spring inwardly to seat in the circumferential groove.

Welding apparatus

A welding ground apparatus comprising at least two members, the at least two members engaged and having at least one angular degree of freedom between them, the grounding apparatus including a biasing member for applying a force to at least one of the at least two members when compressed, the line of action of the force traversing a contact footprint, the contact footprint having a footprint periphery and defined by one of the at least two members.
